Methods: Between March and August 2012, we mailed a survey to 3,000 individuals who had purchased Colorado fishing licenses in 2011. Half were residents (5% senior, 12% combination, 50% annual and 33% 1-day licenses) and half were non-residents (76% annual and 24% 1- or 5-day licenses). We had a valid sample of 2,577 anglers and received a total of 1,404 responses to the survey (54% adjusted response rate; 56% of residents and 44% of non-residents). Highlights of results: Key findings of this survey were:  Among anglers of all types, the 3 most commonly targeted species were rainbow trout, brown trout and cutthroat trout. All anglers desired an increase in opportunity for these species over other species.  Frequent and moderate anglers were more satisfied with their fishing experience in Colorado than infrequent anglers. Moderate and frequent anglers were very satisfied with the variety of fish and waters they could fish in Colorado. Infrequent anglers were not satisfied with the number and size of fish they caught and the complexity of the fishing regulations in Colorado.  Annual, resident license purchasers fished for an average of 24 days in 2011; annual, non-resident license purchasers fished for an average of 17 days. Senior license purchasers fished for an average of 13 days and combination license purchasers fished for an average of 15 days.  Resident anglers were very satisfied with the variety of fish and water available to them to fish, and their ability to eat the fish they caught. Residents reported the highest level of dissatisfaction with the number and size of fish they caught and the availability of wild fish.  Non-residents were satisfied with the variety of fish and water available to them, and their ability to eat fish they caught. Non-residents were more satisfied with all aspects of fishing than residents.  Colorado anglers spent the highest mean number of days fishing for carp, wiper and striped bass, and bluegill, but these were the least commonly targeted species. The three most commonly targeted species (brown trout, cutthroat trout and rainbow trout) averaged the fewest days fished.  The Colorado population between 51 and 70 years old will decrease over the next 30 years and the population between 71 and 90 years old will increase. This change will not likely affect demand for species or types of access, but may increase participating in fly angling and demand for trout species.  Demographers predict that the white, non-Hispanic population in Colorado will decrease, while the Hispanic population will increase in the next 30 years. White and Hispanic anglers prefer similar species to target and locations in which to fish, but Hispanic anglers are much more likely to keep their catch, which may lead to increased harvest pressure on trout stocks in Colorado in the future.  Colorado is predicted to attract immigrants from California, Texas and Arizona in the next 10 to 20 years. This type of in-migration is unlikely to change demand for species or access in an appreciable way. There may be a slight increase in demand for warm-water game fish such as walleye, but this is likely to be overshadowed by desire for cold-water species found more commonly in Colorado.

Colorado Parks and Wildlife coordinates a broad multijurisdictional watercraft inspection and decontamination network to protect waters from invasive zebra and quagga mussels and other invasive species. Recreational watercraft is the main vector of introduction for this harmful invader. Colorado is a headwater state and there are no mussels upstream. State certified inspectors repeatedly intercept watercraft infested with mussels. A total of 281 boats with attached adult zebra or quagga mussels have been intercepted coming into Colorado’s waters from out of state at watercraft inspection and decontamination stations. The infested watercraft were intercepted at Barr Lake, Blue Mesa, Boulder Marine, Boulder Reservoir, Boyd Lake, Canon Marine, Carter, Cherry Creek, Chatfield, Clear Creek, Crawford, Denver CPW Office, Dillon, Electra Lake, Eleven Mile, Frisco Bay Marina, Granby, Grand Lake, Grand Junction CPW Office, Great Lakes Marine, Green Mountain, Highline, Horsetooth, Jackson, John Martin, Lathrop, McPhee, Navajo, North Sterling, Pueblo, Ridgway, Rifle Gap, Roadside (SW Colorado), Ruedi, Shadow Mountain, Spinney Mountain, Stagecoach, Steamboat Lake, Strontia Springs, Sweitzer, Taylor Park, Trinidad, Turquoise, Vallecito and Williams Fork. Zebra and Quagga Mussel Positive Interdiction Sites in Colorado cpw.state.co.us �ZEBRA MUSSELS Where are the infested mussel boats coming from? It is often difficult to determine the exact location of infestation due to the frequency of boating use. Also, numerous interceptions are used boat purchases in which the previous boating history is not known. For these reasons, the source of infestation for more than twenty interdicted watercraft is unknown. The remainder of the infested vessels were coming from Arizona, Arkansas, California, Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Mississippi, Missouri, New York, Nevada (Lake Mead), Oklahoma, Ohio, Pennsylvania, Texas, Utah (Lake Powell), Wisconsin, and the Great Lakes.

The Act defines ANS as exotic or nonnative aquatic wildlife or any plant species that have been determined to pose a significant threat to the aquatic resources or water infrastructure of the state. The Parks Board passed regulations required by the Act on February 20, 2009 and updated them since that time. The regulations require mandatory watercraft inspection, and if necessary, decontamination of all boats coming from out of state, leaving waters with known ANS and boats entering high-risk waters where inspections are required by the managing entity. The focus of the program is to prevent zebra and quagga mussels and other ANS from infesting Colorado’s water resources and threatening our water storage and distribution systems for municipal, industrial and agricultural use. The Colorado ANS Program is highly effective and a model which other states across the nation are learning from. Program Goal and Successes The goal of the program is to protect the state’s natural resources, outdoor recreation and water supply infrastructure through the prevention of new introductions of costly invasive species, such as zebra or quagga mussels, in Colorado. Western states such as Arizona, Kansas, Nebraska, Oklahoma, South Dakota, and Texas, do not have mandatory ANS prevention programs and continue to become infested with zebra or quagga mussels. Colorado has prevented the introduction of these awful invasive species due to the diligent efforts of watercraft inspection and decontamination staff, as well as monitoring, education and enforcement actions. There has never been an adult zebra or quagga mussel found in Colorado. Pueblo Reservoir was de-listed in January 2017 following 5 years of negative detections. All other reservoirs that initially tested positive in 2008 were de-listed in 2014 after 5 years of negative testing. CPW’s ANS Program has worked to stop the continued inoculation of our waters to invasive mussels being introduced by recreational watercraft. Sampling and Monitoring Sampling and monitoring is a key component to the success of the ANS Program. CPW has sampled 584 “at-risk” waters over the last decade and it was through this sampling program that invasive mussel larvae were first detected in Colorado. While CPW ANS staff monitors the state’s public waters for numerous invasive plant and animal species, the focus of sampling is on early detection of zebra and quagga mussels. There are three sampling protocols that target the three life cycles of mussels. CPW also documents native aquatic plants, mollusks and crayfish while performing monitoring activities for invasive species. Colora d o Pa r ks & Wi ldli Protect Colorad o’s Lands and Wate rs Learn How You Can Stop InvaSIve fe SpeCIeS Information and Outreach CPW and its partner agencies have implemented a comprehensive, multifaceted invasive species public education campaign. Accomplishments include distribution of tens of thousands of printed rack cards, brochures, handouts, DVDs and posted signage at offices, boat ramps and other public access points. Additionally, a media relations campaign has been launched using web, radio, print and television. www.cpw.state.co.u s Working Together: Watercraft Inspection and Decontamination (WID) Watercraft inspection and decontamination is a requirement of the ANS Act and continues to be a key component in preventing the spread of ANS into and within Colorado. CPW coordinates the vast network of WID stations that are operated by CPW, the National Park Service, Larimer County, various municipalities and private industry locations. In total, the state has collectively performed over 4.9 million inspections and 119,814 decontaminations since 2008. cpw.state.co.us �2018 Water Resources Development Act The 2018 Water Resources Development Act (S. 3021) was passed by the 115th Congress and signed into law last October. Section 1170 includes a provision which directs the U.S. Army Corps of Engineers to establish, operate, and maintain new or existing watercraft inspection stations to prevent the spread of aquatic invasive species in the Columbia, Upper Missouri, Upper Colorado, South Platte and Arizona (should be Arkansas) River Basins. The provision also authorizes the Army Corps to assist states with monitoring and rapid response efforts in the case of an infestation of quagga or zebra mussels. Green Mountain Reservoir In August 2017, the U.S. Bureau of Reclamation (BOR) detected quagga mussels in Green Mountain Reservoir. The specimen were genetically confirmed to be quaggas by an independent lab for CPW. Rapid Response was initiated by CPW and began immediately among the multi-jurisdictional partnership. Green Mountain is now listed as “suspect” for quagga mussels and containment is ongoing. Resources are needed for infrastructure, security and staffing to prevent the spread through watercraft. Green Mountain Reservoir within Summit County is owned by the BOR as part of the Upper Colorado River Collection System, and is managed for recreation by the White River National Forest. There were no detections in either 2018 or 2019. If there are no detections in 2020, the reservoir will be de-listed in 2021 per regional standards. Mussel Boat Interceptions Infested mussel boat interceptions continue to skyrocket each year. In total there have been 281 watercraft intercepted with adult zebra or quagga mussels attached since the ANS program began. In 2019, CPW intercepted 86 watercraft infested with zebra or quagga mussels coming in from out of state. In 2018, the state intercepted 51 and in 2017 the state intercepted 26 infested watercraft. This exponential growth in infested boat interceptions is directly related to the growing threat invasive species pose to water infrastructure, natural resources and outdoor recreation. The majority of the intercepted vessels were coming from Lake Powell, the State of Arizona or the Great Lakes. All boats were decontaminated to ensure all mussels were dead, and no mussels were visibly attached. An administrative solution in both the House and Senate is needed to correct the typo is Section 1170 from the nonexistent Arizona River Basin to the Senate’s intent of providing resources to the Arizona River Basin with its headwaters in Colorado. Urge the Army Corp to not delay appropriations or planning in the Upper Colorado or South Platte Basins while the Arizona/Arkansas Basin typo is corrected. Support is needed to gain the fiscal appropriations as authorized in the bill. The Stop the Spread of Invasive Mussels Act of 2019 Senator Bennet, along with Senator Daines and Senator Tester from Montana, introduced the Stop the Spread of Invasive Mussels Act of 2019. The bill authorizes the Secretary of Interior through the Commissioner of Reclamation to provide financial assistance to states or local governments for WID. The bill adds several federal agencies, such as the National Park Service, as a member of the ANS Task Force and provides authorization for all members of the ANS Task Force to conduct WID into and out of federal waters. The bill requires the ANS Task Force to report back on any regulatory changes necessary to implement WID prevention or containment. Finally, the bill corrects the typo in Section 1170 of S.3021 to authorize the Arkansas River Basin. Sponsorship and support is needed to pass this bill. The threat of invasion from zebra and quagga mussels is greater than ever due to numerous new infestations in surrounding states such as Arizona, Kansas, Nebraska, North Dakota, Oklahoma, South Dakota, Texas and Utah. Operating and Financials The Supreme Court ruling in case 13SC996 significantly reduced the source fund for the ANS Program (Tier II Severance Tax) as appropriated in the ANS Act. A broad stakeholder effort was called upon to raise funds and determine long term solutions. CPW redirected agency cash and a USFWS Motorboat Colorado Grant to pay for the 2017 boating season, along with over $1M of partnership funds. The Colorado General Assembly provided funding to the ANS Program through SB17-259 and HB18-1338 to be leveraged with federal dollars and other sources to maintain the program over the 2018–2019 boating seasons. In 2018, the Colorado General Assembly passed the Mussel Free Colorado Act (HB18-1008) to provide a new stable funding source through the creation of an ANS stamp for motorized boats and sailboats—$25 for in state residents and $50 for out of state visitors. The ANS Stamp will provide approximately $2.4M (50% of the need) annual funding to the ANS Program. The bill also increases fines for violations and allows CPW to recoup costs for decontamination of quarantined and impounded vessels. Similar to the 2017 joint resolution on ANS which passed the State Legislature unanimously, the Mussel Free Colorado Act continues to encourage federal governments, specifically the Bureau of Reclamation, U.S. Forest Service and Army Corp of Engineers, to provide the other half of the needed funds for the ANS Program since many of the highest risk waters are federally owned or managed reservoirs. How You Can Help • Contact U.S. Senators and Representatives, and the U.S. Army Corp of Engineers, and encourage them to secure an administrative solution to correct the typo in Section 1170 of S. 3021 (WRDA-2018) changing Arizona River Basin, which does not exist, to Arkansas River Basin, which was the intent of the Senate. • Encourage Congressional delegates and the Army Corp of Engineers to provide fiscal appropriations under Section 1170 of S. 3021 for the Upper Colorado, South Platte and Arkansas River Basins. This funding will be used to provide cost share for WID staff, operations, infrastructure improvements, monitoring and rapid response. • Support the passage of The Stop the Spread of Invasive Mussels Act of 2019. • Urge the U.S. Bureau of Reclamation and the U.S. Forest Service to provide funding to CPW for WID staff, operations and improved infrastructure on waters under their ownership or recreational management. • Inform municipal government, county commissioners, state legislators and federal congressional delegates of the potential economic and social impacts that could occur without ANS preventative measures.

ADAMAS, which is updated throughout the year, contains information on over 13,000 lakes and stream segments, and all fish managed by CPW for anglers. The objective was to create a single, quick, reliable and easy-to-access database to help CPW managers enhance angling opportunities and provide information for aquatic scientists and other government agencies researching topics that could benefit Colorado anglers across the state. The actual database is housed on a server in Denver. However the majority of work on the database is conducted by the data analyst within the Aquatic Research Unit at the CPW Fort Collins Research Center. CPW fish biologists and other fishery professionals - including federal agencies, academics and consultants – continually contribute data to ADAMAS. The database holds all the raw data collected annually from surveys across the state and allows CPW biologists, fishery managers and researchers to monitor changes to effectively manage Colorado’s fish resources for anglers. ADAMAS History In the 1980’s, CPW began to standardize survey and data collection methods, allowing for data from all over the state to be stored together. A database would replace paper files, which typically were lost when biologists retired. CPW leadership decided that a statewide, centralized depository for the entire database would benefit everyone. The first rendition of the database, called the Stream and lake Databank, was comprised of only related tables. It has continued to evolve and develop into its present form. The database, now residing on a centralized installation of Microsoft SQL DBMS, is made up of hundreds of related tables. While new data is constantly being added and older data is corrected, the actual database design and structure are also constantly evolving to accommodate new data and assessment techniques. The database currently houses information on over 36,000 individual survey records and over 6 million individual fish, going back all the way to 1875.

Kokanee fry survival has declined since lake trout began naturally reproducing within Blue Mesa Reservoir beginning in the early 1990's. This decline was due to higher predation from the expanding and now larger population of predatory-sized lake trout (Figure 1). Anglers value opportunities to fish for both kokanee and lake trout. Kokanee provide the greatest draw for overall catch and harvest while lake trout provide the greatest draw for their trophy potential. Lake trout over 50 pounds and 44 inches in length have been caught. However, lake trout require plentiful kokanee as prey to achieve such large size (Figure 2). Improving kokanee fry survival by reducing predation from small lake trout is necessary for maintaining abundant kokanee and associated benefits to anglers seeking to catch and eat kokanee or seeking trophy lake trout. Recent study: managing for coexistence of kokanee and trophy lake trout Unsustainable levels of predation by lake trout can lead to rapid declines in kokanee abundance and in lake trout growth and body condition. Immediately following a 90% decline in kokanee abundance during the 2000’s, CPW initiated fall netting efforts for lake trout in 2009 to recover kokanee while still providing for a trophy lake trout fishery. Additional harvest of lake trout is needed to achieve these management objectives. Recent research demonstrated that increased removal of primarily small, young lake trout could improve kokanee fry survival, the overall abundance of kokanee, and produce more trophy lake trout. It is possible that this increased harvest could be achieved through a lake trout harvest incentive program, but may require additional netting if angler harvest is not sufficient. Figure 1. Reconstructed population trajectory of predatorysized lake trout over time (years) based on abundance estimates from netting (SPIN) and mark-recapture surveys. A harvest incentive tournament can lead to improved angler involvement and efficient fisheries management: Fall netting by CPW supplemented angler harvest by removing ~1,200 lake trout annually from 2009 through 2017 while returning trophy-sized lake trout to the water. Angler harvest averaged ~6,000 lake trout annually over this period (Figure 3). As a result of these joint efforts, the abundance of predatory-sized lake trout has decreased recently (Figure 1) and kokanee survival and abundance has improved. However, recent lake trout monitoring surveys indicate that numerous small lake trout are now growing larger and expected to switch to preying on fish. CPW feels there is an opportunity to further encourage angler harvest through a lake trout harvest incentive program which could more efficiently remove enough small lake trout such that netting would not be required. Ninety-six percent of lake trout harvested by anglers and netted by CPW were smaller than 24 inches in length. Figure 2. Average number of kokanee (KOK) per predatory-sized lake trout (MAC) present in Blue Mesa Reservoir over time (years) in relation to when state-record fish were caught.

Across their native and introduced ranges, Brown Trout show a large diversity in life-history traits. For example, some Brown Trout stay within a small section of stream their entire life. Some populations consist of fish that spawn only once, while in other populations, fish spawn multiple times over their lifetimes. There are also populations that are anadromous, where fish move up freshwater rivers from the ocean to spawn, as well as adfluvial populations, where fish migrate between rivers and lakes. Along with these differences in life history, the physical appearance of Brown Trout varies greatly, which could be related to genetics, habitat use, diet, and fish age, among other factors. However, the connection between life-history traits, factors affecting physical appearance, and management in North America is not well studied. Black (top), intermediate (middle), and red (bottom) spotting patterns of Brown Trout from the Middle fork of the South Platte River. Brown Trout were first introduced to the United States in 1883, and subsequently introduced into Colorado in 1890. Different source populations were used to establish these wild Brown Trout fisheries, including lake populations from Scotland and river populations from Germany. Brown trout populations in Colorado are generally considered a mix of these two, and exhibit physical and behavioral characteristics of both as part of their life histories. Understanding Brown Trout life history is an important aspect of managing these populations throughout the state. Brown Trout in the South Platte River The Brown Trout population in the Middle Fork of the South Platte River near Hartsel is of interest to both anglers and mangers due to the unique angling opportunities provided by both Spinney Mountain Reservoir and the state wildlife areas along the South Platte River. Between 2006 and 2011, a stream restoration project was completed in a small section of the Middle Fork of the South Platte to create deeper pools for overwinter habitat and to hold big fish throughout the rest of the year. Between 2013 and 2016, CPW biologists and researchers conducted a tagging study to investigate habitat use by Brown Trout throughout the river. Fish were tagged with passive integrated transponder (PIT) tags containing a unique identification number that can be used to track the location of fish through physical recaptures and scanning during population estimate, and by river-spanning COLORADO PARKS & WILDLIFE • 317 West Prospect Road, Fort Collins, CO 80526 • (970) 472-4436 • cpw.state.co.us �antennas placed in the river that can detect the tags when the fish move past their location. These antennas record the date and time when movements are made year-round. Over the course of the study, three Brown Trout spotting patterns were identified: those with only black spots, those with red spots, and an intermediate spotting pattern between the two. To determine if spotting pattern explained observed movement patterns or the life history of the Brown Trout population in the Middle Fork of the South Platte River, additional data was collected in 2016, including stable isotopes, a technique used to identify chemical signatures in the fish tissue and characterize their diets and where feeding occurred, scales for aging fish, and genetic samples. South Platte River Brown Trout Population Structure and Life History A total of 1,259 Brown Trout were PIT-tagged over the three year study. Brown Trout with typically black spots and larger sizes moved longer distances, crossing all four of the stationary antennae at least once during the study. Although some PIT-tagged fish made long-distance movements, most moved less than 9 miles, with the majority of the fish moving 1 mile or less, suggesting many were river residents. Larger movements were made in the fall (September through October) as well as the spring (March through May). Fall movements occurred during the Brown Trout spawning period, whereas spring movements occurred when the ice was melting. Brown Trout primarily used the section of river at the upstream end of the study area, and Spinney Mountain Reservoir. When Brown Trout chose to move, they generally moved between these two locations fairly quickly, bypassing the habitat in between, including the deep pools in the restoration section, to reach favorable spawning areas or overwinter habitat in the reservoir. Brown Trout with black spots were older than Brown Trout with red spots, and fish with an intermediate spotting pattern fell between the two, suggesting spotting pattern changed as fish got older. Isotope data indicated that black spotted fish and red spotted fish each eat different foods and reside in different parts of the system. Black spotted fish spend most of their time within the reservoir, entering the river to spawn in the fall, and the red spotted fish live primarily within the river. Fish with an intermediate spotting pattern are likely transitioning from life in the river to life in the reservoir as they get older. Genetic testing indicated that the Brown Trout with black spots, red spots, and the intermediate spotting Average age (95% confidence intervals) of Brown Trout with pattern were related and form one adfluvial Brown black, intermediate, and red spotting patterns from the Middle Fork of the South Platte River. Trout population. Brown Trout in the Middle Fork of the South Platte River rely on both the river and the reservoir to complete parts of their life history (e.g., spawning and juvenile rearing versus overwinter habitat and growth), and change spotting patterns as the fish age and use these different habitats. Management of Brown Trout This study allowed biologists to better understand the life history of Brown Trout in the South Platte River. Based on the suite of data collected, these Brown Trout represent one population with an adfluvial life history incorporating characteristics of lake and river source populations historically used to establish Brown Trout in Colorado and North America. The connection between the reservoir and the upstream spawning habitat is important to the life history of the Brown Trout in this system, providing habitats needed to complete different parts of their life cycle. This information will help inform management of the fish in both the Middle Fork of the South Platte River and Spinney Mountain Reservoir, promoting their persistence, and ultimately providing more angling opportunities in both systems. Additionally, knowledge of the life history can be used to guide future river restoration activities in this and other rivers around the state to maximize their success.

Found worldwide, BCWD causes significant complications and death in hatchery trout populations. Outbreaks typically occur at temperatures between 39 and 50F. Infected fish show a broad range of clinical disease signs including lesions, spiral swimming, “black tail”, spinal deformities, and pale or necrotic gills. Mortality can be high if left untreated, and antibiotics are commonly used to treat BCWD. As an alternative, the USDA National Center for Cool and Cold Water Aquaculture (NCCWA) developed a Rainbow Trout strain that is resistant to F. psychrophilum. With the help of Utah Division of Wildlife Resources, psychrophilum-resistant Rainbow Trout (PRR) were incorporated into the CPW hatchery system to help manage BCWD outbreaks. Lesion caused by F. psychrophilum infection Whirling Disease (WD) Whirling disease (WD) is caused by the parasite Myxobolus cerebralis. Spinal deformity, M. cerebralis infection Signs of infection include skeletal deformities, “black tail”, and “whirling” or spiral swimming. WD cannot be treated, and susceptible fish typically die within their first year. M. cerebralis has a complex multi-stage life cycle, making it extremely difficult to remove from aquatic environments. One option for management is to use M. cerebralis-resistant fish. The Hofer strain is genetically resistant to M. cerebralis, however, it is domesticated and shows reduced survival in the wild. To increase survival, CPW crossed the Hofer with wild Rainbow Trout strains. The resulting crosses (HxC, Hofer by Colorado River Rainbow; HxH, Hofer by Harrison Lake Rainbow) are resistant to M. cerebralis, and survive and reproduce in the wild. Stocking M. cerebralis-resistant Rainbow Trout has helped reduce WD in aquatic systems throughout Colorado. Evaluating Dual Resistance via Dual Exposure to BCWD and WD CPW uses the PRR to reduce mortality in the hatchery due to F. psychrophilum outbreaks. However, it is unknown if the PRR are resistant to M. cerebralis. Stocking PRRs with no resistance to M. cerebralis could result in high losses from WD, as well as increased M. cerebralis prevalence. Conversely, although resistant to M. cerebralis, the HxH shows increased mortality in the hatchery during BCWD outbreaks. This study examined if crossing the PRR with the HxH resulted in fish that are genetically resistant to both F. psychrophilum and M. cerebralis.

To test genetic resistance to both pathogens, fish were exposed to F. psychrophilum, M. cerebralis, or both. Fish were exposed to F. psychrophilum using injections under the skin, and to M. cerebralis using bath exposure to triactinomyxons, the waterborne infectious stage of the parasite. Mortality from F. psychrophilum occurs within 28 days of exposure, and was the first measureable endpoint of the experiment. Fish were then reared for six months to allow development of myxospores, the countable form of M. cerebralis in fish, and disease signs and myxospore counts were obtained from the fish remaining at the end of the experiment. The PRR experienced the lowest cumulative mortality when exposed to F. psychrophilum, showing that it was more resistant to F. psychrophilum than either the HxH or HHP. However, with higher myxospore counts than either the HxH or HHP, the PRR did not show any resistance to M. cerebralis. The HxH had much lower myxospore counts and was more resistant to M. cerebralis than the PRR. However, as had been observed in the hatchery, the HxH did not exhibit any resistance to F. psychrophilum. The myxospore counts for the HHP were intermediate to those of the HxH and PRR, and the HHP experienced high cumulative mortality when exposed to F. psychrophilum, showing that it had not gained resistance to F. psychrophilum from the PRR. Coinfection with F. psychrophilum and M. cerebralis increased mortality in the PRR, HxH, and HHP compared to single-pathogen exposure. Left: Cumulative percent mortality (CPM) for the HHP, HxH, and PRR across six treatments, 1) control (no pathogen exposure), 2) F. psychrohilum only (Fp), 3) exposure to F. psychrohilum followed by exposure to M. cerebralis (Fp Mc), 4) M. cerebralis only (Mc), 5) exposure to M. cerebralis followed by exposure to F. psychrophilum (Mc Fp), and 6) mock injection with TYES media (TYES). Right: Myxospores per fish head as a measure of M. cerebralis infection for the HHP, HxH, and PRR in each of the six treatments at the end of the experiment. Management Implications The results of this experiment suggest that it was not possible to create fish that are resistant to both F. psychrophilum and M. cerebralis using the HxH and PRR. In a follow up experiment, we exposed pure strains and their crosses to F. psychrophilum and found that the first generation cross between the Harrison Lake Rainbow Trout and the PRR showed reduced mortality and resistance to F. psychrophilum. Therefore, it may be possible to produce Rainbow Trout that are resistant to both pathogens, though their resistance to M. cerebralis still needs to be evaluated. More research is needed to determine if other strains not included in these experiments can be used to create fish resistant to both pathogens. Until then, hatchery outbreaks of BCWD in susceptible fish such as the HxH can be reduced by maintaining high water quality, flows, and reduced densities to prevent stressful rearing conditions. Using PRRs in hatcheries where F. psychrophilum outbreaks are common will help reduce mortality from BCWD on the unit, but due to their susceptibility to WD, these fish should not be stocked in aquatic systems in which M. cerebralis is established.

Fish loss in irrigation canals is known to be a large problem in the western U.S. but the impact on fish populations in Colorado is unknown. The South Canal is an irrigation ditch near Montrose, Colorado that diverts an average of 857 cubic feet per second from March to November from the Gunnison River for agriculture. The construction of a hydropower plant was expected to increase mortality of fish in the canal so an electric fish barrier was installed at the diversion structure in 2012. Research Objectives The objective of this work is to evaluate if electric fish barrier technology can reduce the loss of sport fish in irrigation canals in Colorado by monitoring fish populations in the South Canal and documenting tagged fish that cross the barrier. Electric Fish Barrier The fish barrier was operational before the 2013 irrigation season. It consists of a series of vertically suspended electrodes across the east portal of the Gunnison Tunnel. The system uses pulsed direct current (DC) to deter fish. DC is the safest type of electrical current for fish and has been shown to repel fish without injuring them. The barrier was designed to exclude broodstock rainbow and brown trout with a field strength of 1 volt per inch, a relatively low power setting for electric fish barrier designs in the United States. Pulsed DC current is size-selective; it affects larger fish more than smaller fish. Approach A total of 23,031 fish from 3 to 29 inches in length were tagged and released in the Gunnison River above the barrier. Fish were removed from the canal before the barrier was operational and annual electrofishing surveys were used to estimate fish populations and look for tagged fish.

Fish bioenergetics is the study of how factors such as metabolism, water temperature, and quality of prey regulate the ability of fish to convert energy from food into body mass or growth in weight. Much effort has been devoted to developing models that describe the bioenergetic characteristics of different species of sport fish found in Colorado’s lakes and reservoirs and elsewhere. These models help biologists address a number of critical fisheries management questions and guide efforts to improve growth within fish populations and ultimately fishery quality. For example, fish bioenergetics is useful for answering: o What limits fish growth the most: temperature, prey availability, or the quality of prey? o How much prey do predators eat? Is it too much, or can prey populations handle higher levels of predation? o What is the optimal number of fish to stock based on the available food supply in a lake or reservoir? Caloric content of fish: the currency of bioenergetics Knowing the “energy richness” of fish is important because it is an indicator of fish health, prey quality, and because energy is the common currency used to convert the amount of food eaten by a fish into weight gain or loss in bioenergetics models; this approach is similar to counting calories in the foods we eat and tracking the fate of those calories once ingested. Many factors influence the caloric content of fish, and it is possible for the same species to differ among lakes. In this study, we estimated the caloric content (number of calories in one gram of fish tissue) of key predator and prey fish found in Colorado’s coldwater reservoirs to improve the applicability of bioenergetics models to CPW’s management of these species. The average caloric content of different species examined is shown in the figure below: The most striking observation was the high caloric content of kokanee salmon, which was 2-fold or more greater on average than the other species of prey fish available to predators. For example, a lake trout in Blue Mesa Reservoir would need to eat two or three rainbow trout, white suckers, or yellow perch to obtain the same amount of energy gained from eating a single kokanee of equal size. This observation also indicates that kokanee are more efficient consumers of zooplankton, a primary food source for prey fish in our fluctuating coldwater reservoirs. Thus, kokanee help maximize fishery productivity. Overall, this research highlights the irreplaceable role kokanee play as a sport fish for anglers and as energy rich prey fish for predators in Colorado’s reservoir food webs. Managing for populations of healthy, abundant kokanee ensures the long-term maintenance of CPW’s kokanee stocking program and benefits therein to anglers seeking to catch and eat kokanee or seeking to catch predatory sport fish like lake trout that rely on plentiful kokanee for supporting high feeding and growth.

Many rivers in Colorado contain man-made structures that create partial (obstacles) or complete barriers depending on the fish species and life stage. Habitat fragmentation associated with instream barriers is a serious threat to Colorado’s Species of Greatest Conservation Need (SGCN) and sport fisheries. Therefore, it is important that fisheries managers (A) identify and evaluate the influence of instream structures on fish populations. Fish Passage Research Objectives The primary goal of fish passage research is to restore connectivity in fragmented river systems by: (1) evaluating the effectiveness of existing fishways; (2) evaluating the barrierpotential of common river structures; and (3) establishing fish swim performance criteria for native and sport fishes. Current Fish Passage Research Projects Active fish passage research projects include: (1) evaluation of native fish passage at existing fishways located on Front Range transition zone streams; (2) evaluation of fish passage at instream whitewater park structures; (3) laboratory studies to develop fish swim and jump performance criteria for Colorado fishes where data is lacking; and (4) development of new techniques and technologies for investigating fish movement and passage in rivers. (B) Fishway Design Fishways, or “fish ladders”, are engineered structures designed to facilitate passage around an obstacle or barrier. Fishways attempt to incorporate species- and life stagespecific swimming and jumping abilities into designs. Common elements of successful fishways include: (1) low velocity pathways that do not exceed burst speeds or endurance capabilities for target species (Figure A); (2) water depths that do not limit swimming performance (Figure B); (3) vertical drops that do not exceed the jumping ability for target species - note that many species native to Colorado do not exhibit jumping behaviors (Figure C); (4) sufficient attraction flow, or the flow that emanates from a fishway entrance, to ensure that fish can locate the fishway; and (5) maintenance of the above design elements over the expected range of streamflows.

Native Colorado fishes have unique morphological characteristics that are adapted to the natural conditions found in each aquatic habitat type. These adaptations affect the swimming abilities of fish, influencing how they move through and use diverse habitats.

These parasites have the potential to negatively influence salmonid fisheries throughout Colorado because they can impair fish growth, behavior and survival. To date, only one species of gill lice has been identified in Colorado, Salmincola californiensis. This species of gill lice is known to infect kokanee salmon, cutthroat trout, and rainbow trout throughout the state. No infection of gill lice has been confirmed on any other species of fish in Colorado. CPW continues to work on potential management actions or other approaches to minimize the negative impacts of gill lice on Colorado’s valuable native and sport fisheries. Specifically, CPW is attempting to: • Assess the current infection presence and intensity of gill lice. • Determine the extent of negative effects on fish populations throughout the state. • Identify conditions leading to high levels of gill lice. • Identify potential management actions and approaches to reduce negative impacts on fisheries. Gill Lice Background Gill lice (of the genus Salmincola), are a parasitic zooplankton that generally attach to the gills, mouths and fins of salmonid fishes (e.g., salmon, trout). Since the initiation of the gill lice project in Colorado in 2012, gill lice have been identified on cutthroat trout, rainbow trout and kokanee salmon. It is important to note that gill lice infestation does not make fish unsafe for consumption. Heavy gill lice infections can prevent fish from breathing normally, inhibiting oxygen uptake through damaged gill filaments. Gill lice infestations can also negatively affect fish behavior, immune system function, growth, warm water tolerance and ultimately survival. Gill lice were first reported in Colorado in the early 1900’s. Until relatively recently, the negative effects associated with gill lice on fish were limited to infestations in hatcheries, though the presence of gill lice in some Colorado water bodies outside of hatcheries was known. However, more recently, anecdotal evidence has linked declines in fish populations with the occurrence of gill lice, and it is important to understand these more recent observations. Specifically, kokanee salmon populations in many lakes throughout the west have completely collapsed after becoming infected with gill lice. COLORADO PARKS & WILDLIFE • 1313 Sherman, Suite 618, Denver, CO 80203 • (303) 866-3437 • cpw.state.co.us �Kokanee salmon and native cutthroat trout are ecologically and economically important fish species in Colorado that have experienced recent population declines. These populations are especially important to conserve, preserve and protect. Gill lice research is focused on identifying and developing options for limiting the spread of gill lice to these populations as well as minimizing negative effects from gill lice in native fish populations where gill lice are already present. This research will help maintain and potentially enhance these valuable fisheries and the ecologically and economically important fish species that support them. CPW research on gill lice is especially important because controlling or eliminating the parasite in wild fish populations is currently diffic ult or impossible, and this project is aimed at gaining an understanding of gill lice to address this challenge and present viable management options to reduce negative impacts associated with gill lice spread.

Lake trout are top predators, reproduce naturally, and are important sport and food fish for anglers in Colorado’s lakes and reservoirs. Keeping close tabs on their abundance and size structure is necessary for assessing the appropriateness of harvest regulations, ensuring lake trout remain in balance with prey fish populations, and determining whether management goals are achieved. However, estimating the abundance of lake trout in our large coldwater reservoirs at the frequency needed to inform management using conventional methods such as mark-recapture is impractical. Thus, CPW researchers and biologists evaluated the utility of “Summer Profundal Index Netting” (SPIN) for application to lake trout in Colorado beginning in 2011. Developed by the Ontario Ministry of Natural Resources, SPIN is a standardized gill netting method for estimating the density of lake trout ≥12 inches over a 1-2 week period. Colorado has since adopted SPIN for monitoring lake trout populations in Blue Mesa Reservoir, Grand Lake, Lake Granby, and Taylor Park Reservoir. Survey design, implementation, and results: Standard gill nets specific to this protocol are set for two hours during daylight along the bottom in random orientation when surface temperatures exceed 64°F. You may see these nets being set or pulled at these lakes by CPW personnel during the summer months. The number of sets depends on the surface area of the lake or reservoir. Set locations cover depth intervals of 6-32 ft, 32-64 ft, 64-96 ft, 96-128 ft, 128-192 ft, 192-256 ft, and >256 ft. Sampling is also conducted in different portions of the lake or reservoir if necessary to account for differences in lake trout habitat. Catch rates of lake trout in the gill nets set in Colorado systems are compared to catch rates of lake trout in the same type of gill nets in other water bodies where estimates of lake trout density were available. The advantage of this method is the use of data from numerous other systems as a calibration tool to quantify lake trout densities and abundances in Colorado. Please see Lepak (2011) and Hansen (2018) for additional information. Management implications: Results from each SPIN survey conducted to date shows that lake trout density varies 7-fold across study systems. This indicates that processes governing the productivity of lake trout vary or operate differently in each lake or reservoir. Thus, management plans and corresponding harvest regulations must be tailored to each individual lake trout population in order to achieve desired goals for the fishery.

Although fish are an excellent source of protein, integration of mercury into lake and stream food webs results in traces of mercury being present in fish, sometimes at levels that present health concerns to people who consume fish regularly. Because mercury levels increase as you move up the food chain (i.e., ‘bioaccumulate’), concentrations are highest in top predators such as walleye. Through monitoring and research, both the Colorado Department of Public Health and Environment and Colorado Parks and Wildlife (CPW) work to help anglers maximize the benefits of consuming fish while protecting themselves and their families from mercury in the environment. How does mercury get here? Mercury is released into the atmosphere through a variety of natural (e.g., forest fires) and human-caused (e.g., burning fossil fuels) pathways. Mercury can then disperse far from its source before being deposited into lakes and streams, making it difficult to control. While national and global actions to reduce mercury pollution are essential, strategies at the local scale are needed to protect the health of Colorado’s anglers. A recent study on Narraguinnep Reservoir (southwest Colorado) conducted by CPW and researchers from Colorado State University found that ‘triploid’ walleye (have a third set of chromosomes and cannot reproduce naturally) stocked by CPW had 22-24% lower mercury concentrations on average than their naturally-reproducing ‘diploid’ counterparts (have a normal number of chromosomes). This study revealed that stocking triploid fish alone or in tandem with other mitigation strategies can lead to safer fish for anglers to eat. Map of Colorado showing waters with a current fish consumption advisory (red balloons) versus those without (green). Interactive map accessible here: https://cdphe.colorado.gov/waterquality/clean-water/rivers-lakes-andstreams/fish-consumption Why do triploid walleye bioaccumulate less mercury? The answer begins with how and why triploid walleye are produced by CPW. Every spring CPW collects eggs from wild populations of walleye to raise in the hatchery and stock fry into reservoirs that support high angling pressure. Some of these eggs are specially treated to produce triploids. Triploidy is induced by placing fertilized eggs into a hydrostatic pressure chamber for a defined period (see images to right). As a result, the fry that hatch retain an extra set of chromosomes, rendering them incapable of naturally-reproducing over their lifespan. Because triploid walleye are sterile, they can be stocked to support sport fisheries in strategic locations where natural reproduction is not wanted. As this new research discovered, the inability of triploid walleye to reproduce also affects their mercury levels. Spawning is energetically costly, particularly for female fish that need to develop eggs. As a result, diploid walleye need to eat more food to grow and successfully spawn every year when compared to triploid walleye. Since most (>95%) of the mercury present in predatory fish comes from their prey, eating less food to grow the same amount means triploid fish are exposed to less mercury, and have lower mercury concentrations.

The goal of that study was to establish what the native range of these fish was prior to European settlement. While these trout look similar to each other in outward appearance, inspection of their DNA revealed that six discrete lineages historically called Colorado home – essentially one in each major drainage basin. Four lineages are still found on the landscape today: two that comprise Colorado River Cutthroat Trout west of the Continental Divide, Greenback Cutthroat Trout in the South Platte River drainage, and Rio Grande Cutthroat Trout in their namesake river basin. The authors ©KEVIN ROGERS/CPW Distinct lineages of Cutthroat Trout evolved in six major drainage basins in Colorado Specimen collected from the San Juan River by C. E. Aiken in 1874 (now at the National Museum of Natural History in Washington D. C.) reported that the remaining two lineages were thought to be extinct: the Yellowfin Cutthroat Trout historically found in the headwaters of the Arkansas River, and one native to the San Juan River that was only known from two specimens collected near Pagosa Springs during the Wheeler Survey in 1874 while mapping the territories in what is now the American southwest. After learning that a previously unknown lineage of Cutthroat Trout was native to the San Juan basin, we launched an intensive search to determine if any relict populations remained tucked away in the corners of the rugged San Juan Mountains of southwest Colorado.

All fish are vulnerable to predation by larger fish during some phase of life. If predation is high and persistent, stocked fish may not survive long enough to grow to a size that can be caught and harvested in the numbers desired by anglers. In these situations, management actions such as stocking larger fish or adjusting harvest regulations on predators could boost survival. Determining whether different species pose a significant predatory threat to stocked sport fish, and if so, how to best manage the situation, first requires an examination of the interactions among suspected predators and stocked fish. Recent study: threat of yellow perch to stocked kokanee salmon fry Yellow perch were first detected by CPW in Blue Mesa Reservoir, Colorado’s premier kokanee salmon fishery, in 2001. Yellow perch feed on Daphnia (food for kokanee), other invertebrates, but also small fish. There was growing concern and perception from the public and some angler groups that yellow perch were having a detrimental effect on the stocked kokanee fry that maintain this phenomenal fishery. CPW determined that it was important to address these concerns objectively by conducting a focused study on the subject. During 2016, researchers estimated the seasonal diet and habitat use of yellow perch and compared these to brown trout and to the habitat use and growth of kokanee fry. Brown trout have been present since the reservoir was filled in 1965 so they were a good reference species for gauging the predatory threat of yellow perch. Key results and management implications: Contrary to perceptions, yellow perch showed a limited predatory threat to kokanee fry. Yellow perch behaved similarly to brown trout by occupying nearshore areas away from offshore kokanee and eating mostly crayfish and insects throughout the year. Predation by yellow perch and brown trout on kokanee was brief and confined to the inlet during spring when fry stocked upstream entered the reservoir. The pie charts below show how quickly kokanee fry disappeared from the diet of each predator. Kokanee were 50% of stomach contents for each species the morning fry entered the reservoir, but dropped to 0% one week later. Because brown trout were more abundant and consumed more individual fry, their predation on kokanee in the inlet was 39-times greater than yellow perch. Kokanee fry outgrew 58% of adult yellow perch by June and 95% by October, further limiting predation. Yellow perch did not measurably affect the amount of Daphnia available to kokanee. This research highlights the importance of addressing uncertainties with appropriately designed studies relevant to the species and reservoir in question to guide informed management decisions.

The German Rainbow (GR), or Hofer, a resistant but domesticated Rainbow Trout strain, has been crossed with other Rainbow Trout strains to maintain both whirling disease resistance and wild survival characteristics. Crosses of the GR with other wild strains, such as the Colorado River Rainbow and Harrison Lake Rainbow Trout, are used for stocking various locations, for instance in rivers versus lakes, dependent upon life history characteristics of the wild strain and the management objectives for each body of water. Since these crosses are a relatively new addition to Colorado’s stocking program, the effects of fish size at stocking and variety were evaluated to determine which stocking methods result in increased post-stocking survival and recruitment in newly-established whirling disease resistant Rainbow Trout populations. Rainbow Trout Stocking Evaluations in the upper Colorado River Subcatchable Stocking Evaluations A stocking strategy that was adopted in the years after whirling disease became established in Colorado, prior to the advent of resistant strains, was the use of large (> 6 inches) subcatchable fish. This was done because larger fish were less susceptible to whirling disease infection and predation. Whirling disease resistant Rainbow Trout, a cross between the GR and the Colorado River Rainbow Trout strains (H×C), were first stocked into the upper Colorado River below Windy Gap Reservoir in 2006, with additional stocking events in 2009 and 2010. These resistantStocking Floy-tagged H×C in Colorado River strain stocking events were also conducted with large subcatchable fish, similar to previous stocking events with susceptible strains. Prior to being stocked, all fish were individually tagged using external Floy tags to identify individuals upon recapture during annual population estimates. Although some natural reproduction took place in the upper Colorado River during this time, wild fry numbers remained low and little recruitment to the adult population occurred. As a result of both the low post-stocking survival of the stocked subcatchable fish and the low numbers of fry produced by these fish, the adult Rainbow Trout population continued to decline from 91 fish per mile in 2008 to 6 fish per mile in 2011 (Figure A; Fetherman et al. 2014).

Subcatchables are often held in the hatchery for six months or more to get the fish to larger sizes for stocking, whereas fry are stocked 1.5 months after hatching, reducing the amount of time spent in the hatchery and the potential influence of the hatchery environment on post-stocking survival. Use of larger subcatchables was no longer necessary due to the inherent resistance of the new strains. H×C were first stocked as fry in the upper Colorado River in 2013, with H×C fry continuing to be stocked annually through 2016. Fry were distributed by raft in appropriate fry habitat throughout the upper Colorado River. Electrofishing estimates conducted throughout the study section showed that the H×C fry persisted as well as naturally-produced brown trout fry in the same reaches. Additionally, the number of adult Rainbow Trout per mile increased each year following the commencement of fry stocking (Figure B), suggesting that the H×C fry were recruiting to the adult population. As such, stocking H×C fry versus subcatchables appeared to be the best stocking strategy for the Colorado River, and similar rivers across the state. Stocking H×C fry in the Colorado River German Rainbow (GR) versus H×C Fry Stocking Electrofishing for stocked rainbow trout fry The observed survival of the H×C fry was promising. However, studies had shown that eventual dilution of resistance of these stocks could be a concern (Fetherman et al. 2012). Reduced resistance in future generations would be much less likely when stocking pure GR fish. Therefore, stocking pure GR as fry could be an option for establishing whirling disease resistant Rainbow Trout populations in certain situations. Comparative Survival of GR and H×C Fry In a recent collaborative study with Colorado State University, a laboratory and field experiment were undertaken to compare the post-stocking survival of GR and H×C fry. The field experiment was conducted in one mile reaches of nine Colorado streams, selected for consistency in size and physical habitat characteristics. Each stream was stocked with 5,000 GR and 5,000 H×C fry, and survival was assessed at two months, six months, and one year post stocking. After one year in the streams, the strains survived equally well. In the laboratory experiment, equal numbers of GR and H×C were stocked into tanks with brown trout as predators and held for 24 hours. Again, survival did not differ between the strains. The results of this study indicated that stocking the GR as fry may be a viable option in some streams where whirling disease is enzootic (Avila et al. In review). To test this in a larger river system, GR fry were stocked in place of H×C fry in the Colorado River in 2016, and continue to be evaluated annually for survival and recruitment to the adult population. Fry stocking and recruitment evaluations will continue in the upper Colorado River through 2022. GR fry two months post-stocking References Avila, B. A., D. L. Winkelman, and E. R. Fetherman.

CPW stream reconstruction specialists and engineers are available to share conceptual designs for structures successfully used throughout Colorado on all sizes of streams. These designs ensure that water users can fully divert under their decreed water rights while allowing fish access to the entire reach of stream, at little to no additional costs. Designs range from the traditional concrete diversion structure with associated rock ramps to stand-alone boulder cross-vanes, or a combination of concrete diversion structures and boulder cross-vanes. TRADITIONAL DIVERSION WITH ROCK RAMP BOULDER CROSS-VANE DIVERSION TRADITIONAL DIVERSION WITH ROCK RAMP BOULDER CROSS-VANE DIVERSION �Potential benefits of these types of diversion structures include: • • • • • • Allowing full diversion of decreed water rights while facilitating fish and boat passage Increasing habitat connectivity for fish Improving recreational potential and reducing hazards Withstanding high flows (boulder cross-vane diversions on Boulder and South Boulder Creek survived the recent flooding, minus a few boulders) Serving as a temporary diversion structure during this period of high construction costs, or while the owner pursues additional financial assistance Enhancing stream health without impacting ability to fully divert and use water If you are interested in exploring this approach to rebuilding, please contact: Ken Kehmeier, Colorado Parks and Wildlife 317 W.

Highest detections occur in the Pacific Northwest and Midwest. Renibacterium salmoninarum, the bacterium that causes bacterial kidney disease (BKD), was first described in Scotland in 1930, and first detected in the US in 1934. BKD is now found in trout and salmon throughout the US and worldwide, and can cause significant mortality in infected populations. In the US, the bacterium is most commonly detected in Coho and Chinook Salmon in the Pacific Northwest, and Brook Trout and Brown Trout in the Midwest. The transfer of infected eggs and the practice of pasteurizing fish by-products for fish feed (now discontinued) are suspected to have contributed to the worldwide spread of the pathogen. R. salmoninarum can be transmitted in two ways, presenting challenges for prevention and management. Horizontal transmission of the bacteria is not completely understood. However, fish may become infected through direct contact with another infected fish, ingestion of contaminated fecal matter, or contact with a contaminated water source from which the bacteria enters through the gills, eyes, gut, and external injuries of the fish. Vertical transmission occurs during the spawn. Bacteria in the female find their way into the eggs during egg development. There is no method for safely disinfecting the inside of the eggs, and using iodine to disinfect the egg surface during hatchery spawns is not effective for preventing vertical transmission. Horizontal and vertical transmission of R. salmoninarum. R. salmoninarum is a regulated pathogen in Colorado. Current regulations prevent the transfer or stocking of infected fish. While infrequently found in Colorado since the 1960’s, it has recently been detected in six state and federal hatcheries. In 2015, R. salmoninarum was detected in the CPW Glenwood Springs Hatchery. To eradicate the pathogen and prevent stocking infected fish, the hatchery was temporarily depopulated. R. salmoninarum was also detected in other CPW hatcheries rearing valuable brood stocks of whirling disease-resistant Rainbow Trout and Native Greenback Cutthroat Trout, and depopulation of these hatcheries was not an option. Recent management options have focused on methods to prevent vertical transmission during fish spawning, although other approaches are also being examined. Management Options for Controlling Bacteria Transmission Lethal spawning has been evaluated in Rainbow Trout and Cutthroat Trout brood stocks at the CPW Poudre Rearing Unit (PRU) and Fish Research Hatchery (FRH). Eggs are fertilized and collected as normal from brood fish during the spawn. After being spawned, adult fish are euthanized and tested for R. salmoninarum. Eggs from positive parents are then culled so that only eggs from negative parents are retained on the unit for stocking and management purposes. This technique has shown promise in preventing vertical transmission. However, more research was needed to understand the transmission rates of R. salmoninarum, develop management and regulatory protocols to decrease the prevalence of the pathogen within hatchery brood stocks, and limit the dissemination of positive progeny to other waters and hatcheries in Colorado. COLORADO PARKS & WILDLIFE • 317 West Prospect Road, Fort Collins, CO 80526 • (970) 472-4436 • cpw.state.co.us �Treatment Adults Progeny Antibiotics administered orally or by injection have been shown to reduce bacterial Control 10 Tanks 67 Families concentrations in fish.

Negative Positive salmoninarum were produced by both treated and control fish that had tested negative for the bacteria. Additionally, positive control adults produced negative progeny. Results also indicated that the male may play a role in vertical transmission in inland trout, a significant finding as only females were previously known to contribute to vertical transmission of the bacteria. This study revealed several unknowns regarding pathogen transmission that needed to be answered for effective management in Cutthroat Trout. CPW and Colorado State University are currently conducting two studies to better understand transmission rates in Native Greenback Cutthroat Trout. Transmission Studies in Native Greenback Cutthroat Trout Horizontal Transmission Horizontal transmission of R. salmoninarum within a hatchery may pose a risk to fish throughout the unit, as well as feral fish in the river below a unit if the bacteria are present in the hatchery effluent. In summer 2019, two sentinel cages were deployed in six locations at PRU and at three time periods encompassing a range of optimal temperatures for bacterial growth (10-18°C). Each cage housed 10 Cutthroat Trout. After 30 days, fish were collected and tested for R. salmoninarum. Only one fish out of a total of 360 tested positive. The cage containing the positive fish had been deployed near highly-positive Rainbow Trout. These results suggest the rate of horizontal transmission to fish both on, and in the river below a positive unit may be insignificant, even when conditions are optimal for the bacteria to persist. Vertical Transmission Eggs from unique male-female pairs of Cutthroat Trout were collected during the spawn at PRU in May 2019. Adult fish were tested for R. salmoninarum after being spawned to determine the potential infection status of the progeny created from these spawns. Thirty-two tanks of progeny are being reared at the FRH: one containing progeny from a male negative × female negative pair, six from a male positive × female negative pair, four from a male negative × female positive pair, and 21 from a Progeny collected from positive adults male positive × female positive pair. Progeny from each tank will be tested for R. salmoninarum and associated antibodies, indicating that the progeny had mounted an immune response to the bacteria at some point prior to the testing, at six months and one year of age. The results will be used to understand vertical transmission rates, male and female contributions to vertical transmission, and the bacterial load at which transmission occurs from parent to offspring. Overall, the results from the transmission studies will be used to inform future management options. Results from these transmission studies will be available in 2021.

Today, the three species occupy only 50 percent of their native range in the state. Colorado wildlife managers are concerned about the range contraction and the invasion of non-native suckers, which hybridize with the native suckers. Dam construction that obstructed fish movement, increased water diversions and reservoirs replacing free flowing streams as habitat may have influenced the range contraction. The remaining free-flowing water habitat below reservoirs has also changed - colder temperatures, less fluctuation in water levels and reduced sediment. Four related native fish - the bonytail chub, the razorback sucker, the humpback chub and the Colorado pikeminnow - experienced greater range reductions and are federally listed endangered species. Colorado wildlife researchers want to prevent additional federal Listings. Three Species Research Objectives To prevent a federal endangered species listing for these three native fish species and the resulting restrictions on state management options, Colorado Parks and Wildlife (CPW) will create a conservation plan to protect and enhance the remaining populations. Under that plan, CPW could expand and repatriate tJ1e three species, using hatchery produced offspring from captive broodstock. CPW has several research projects underway. CurrentThree Species Research Projects Field work to address the various objectives was initiated in 2012. Scores of randomly chosen sites witJ1in tJ1e historic range have been visited in 2012 and 2013 lo determine whether three species fishes are present. H undreds of genetic tissue samples an d hundreds of fin ray bones have been collected and are undergoing analysis.

Flannel.mouth sucker genetic analyses also revealed populations that exchange genetic material and tl1at exhibit considerable genetic diversity at the individual population level. One broodstock from tl1e Northwest Region has been acquired. Another will likely be obtained for tl1e Soutl1west Region in tl1e future. Additional genetic analyses are underway using a second method to confirm the results of prior research. Roundtail chub broodstocks have been held at CPW's NASRF facility for a number of years preceding the current research effort. Offspring from tl1e broodstocks are stocked in soutl1western Colorado and on tl1e Jicarilla Apache Indian Reservation in New Mexico. Cutting fin ray bone All of the three species are considered to be relatively longlived, witl1 specimens exceeding 20 years of age known for each species. Large, mature flrumelrnouth suckers tagged using passive integrated transponders (PIT) in the Colorado River in 2003 have been detected eight to ten years later as tl1ey passed over stationary PIT tag antenna between 2011 and 20 13. Fin rays are known to be suitable structures for aging these longlived fish, comparable to using otolitl1s - the bone from the inner ear - which require lethal srunpling. Models to predict native sucker biomass from two-dimensional strerun hydraulic modeling were developed for western Colorado rivers in the 2000s. In the srune study, bluehead sucker abundance was found to be a reliable indicator ofbaseflows adequate to sustain the entire native fish assemblage.

Many of Colorado’s coldwater lakes contain fish species, such as suckers and minnows, which provide little value to anglers, compete with managed sport fish, and have the potential to reduce water quality. However, these undesirable fish may be valuable prey items. Sterile fish that have the ability to grow to predatory size quickly and eat the unwanted fish could act as a biological control agent and provide a unique fishing opportunity. Being unable to reproduce, sterile fish can be closely managed through stocking and harvest regulations. Tiger trout, a sterile hybrid between male brook trout and female brown trout, have the potential to fill this role. Tiger trout have already been stocked in some Colorado lakes. Our understanding of what tiger trout eat and how well they grow and survive in lakes with different species of undesirable fish remains limited, and should be fully investigated as a management tool. Fine-mesh net full of fathead minnows. Flushing the stomach of a young tiger trout to evaluate diet (this fish was eating insect larvae). Three-year-old, 5 ½ lb tiger trout from a lake containing fathead minnows. Study objectives Factors such as number of tiger trout stocked per acre of lake and the presence of small-bodied minnows versus largerbodied suckers may affect the ability of tiger trout to grow quickly enough and survive long enough to eat and suppress the population of undesirable fish. The objective of this research is to quantify the feeding, growth and survival of tiger trout stocked into lakes with different species of undesirable fish. Results will help CPW prioritize which lakes receive tiger trout, inform appropriate numbers to stock, and calibrate expectations on the effectiveness of tiger trout as a biological control agent. Informed stocking translates into (1) efficient use of the limited number of tiger trout produced by our hatchery system, (2) a greater chance tiger trout will perform well at the onset of stocking, and (3) more rapid development of a quality fishing opportunity for anglers. Early results Preliminary observations suggest that tiger trout grow well and can suppress populations of undesirable fish in lakes containing small-bodied minnows. For example, based on catch rates in nets (number of fish captured per hour of soak time), fathead minnows were much more numerous in three lakes where tiger trout were either absent or only present for one year (blue bar in figure to right) compared with two lakes where tiger trout were present for 2-3 years (red bar). In addition, tiger trout grew from an average of 4.0 inches at time of stocking to 19.2 inches after just 3 years in one of the lakes. Continued study and monitoring is needed to validate this apparent strong influence of tiger trout. COLORADO PARKS & WILDLIFE • 317 W.

The “toe” is the region at the base of the bank most prone to erosion where it transitions from a vertical to horizontal plane. Using large wood to restore streams is not a new concept. Toe wood evolved from the use of root wads to stabilize streambanks and was originally called “root rap,” derived from the term “riprap,” with the earliest applications from the 1960s (Rosgen 2019). Toe wood is useful for temporarily stabilizing banks until riparian vegetation becomes established, creating a “living,” vegetated streambank for long-term stability. CPW research has documented the direct benefits of toe wood functioning as fish habitat by improving habitat complexity, increasing fish population abundance and biomass, and enhancing pool depths. Specifically, toe wood-treated pools were deeper (Figure B; average difference = 1.5 ft), held more quality (>14“) adult Brown Trout (× 19), higher Rainbow Trout biomass (Figure C; × 8.1), and higher total Brown Trout abundance (× 2) than pools without large wood. In addition, total fish population abundance (× 1.5) and biomass (Figure D) were highest in toe wood pools (Kondratieff and Richer 2022). Our research has demonstrated the effectiveness of toe wood as a bank stabilizing technique and for riparian vegetation establishment, providing increased shading, overhead cover, and terrestrial insect habitat, thereby indirectly benefitting fish populations (Figure E). (A) (B) (C) (D) �Why Toe Wood? Human activities have led to an overall reduction in the amount, size, and sources of wood found in natural channels. Many studies have demonstrated the value of large wood for fish habitat in streams. Wood deposited on outside channel bends or within pools can induce scour, enhancing pool depths in streams. In contrast, wood deposited in the middle of stream channels in riffles or glides can induce deposition leading to island formation and development of complex side channels. Wood deposited on floodplains creates roughness that traps and promotes deposition of rich, nutrient-laden fine soils that benefit riparian plant species. Toe wood can be used to improve physical habitat conditions and increase carrying capacity for fish if it addresses limiting factors such as a lack of low flow refugia (i.e., deep pools), undercut banks, or habitat complexity. A major benefit of using toe wood as an alternative to other toe-stabilizing techniques like rock or boulder materials is that wood is a natural, biodegradable material. Over time, wood decomposes providing food, nutrients, carbon inputs, and other ecological benefits back to the stream and riparian ecosystem that boulders, rock, or concrete riprap materials do not provide. Toe wood installations can be done using completely natural and native materials without the use of steel bolts, cables, anchors, or large ballast boulders. This serves as an economic advantage of toe wood for use in trout streams found within the Rocky Mountain region as sources of woody materials are readily available in close in proximity to project sites, reducing processing, transporting, and hauling costs. Limitations Toe wood is not recommended for use in every river setting in the same way that naturally occurring large wood is not found in every stream. Some places where toe wood is not recommended include deep canyons or other places where floodplains are non-existent, including highly-confined river channels. Toe wood should not be installed immediately upstream of bridges, culverts, and other locations where dislodged wood pieces can hang up on structures downstream causing blockages or obstructing river flows. River locations where there are multiple user groups such as kayakers and rafters might not be good candidates for installing toe wood for human safely reasons since wood in streams can form dangerous hydraulic conditions that can increase drowning risk. Other design considerations that might limit the use of toe wood in certain river settings include consideration of the buoyancy, quality, and type of wood materials available. Toe wood installed in locations that are subject to high levels of angler or cattle foot traffic should include fencing or other exclusionary devices to limit disturbance to erosion-prone outside banks and protect riparian plantings.

When whirling disease first appeared in the state in the 1980s, CPW researchers started exhaustive projects to control the spread of whirling disease, limit the damage to fisheries and develop other solutions. The CPW work also includes cooperative investigations with researchers in other states to coordinate resources. Whirling Disease Background Whirling disease is caused by a microscopic parasite that infects trout and salmon, resulting in severe deformities and death in young fish. The disease gets its name from the abnormal whirling or erratic tail chasing movements of some infected fish. Symptoms also may include a black tail in young fish and a deformed skull or spinal column in adult fish. There is no known cure for fish infected with the parasite. Impacts of Whirling Disease in Colorado A shipment of trout from a private, out-of-state hatchery accidently brought the parasite to Colorado in the 1980s. By the mid-1990s, whirling disease had spread throughout most of the state’s major river drainages. Whirling disease has impacted rainbow, brook and cutthroat trout populations throughout Colorado, and is known to occur in high mountain lakes above 12,000 feet. The parasite also infected most of the state’s coldwater hatcheries, reducing production and fishing opportunities for anglers. Whirling disease doesn’t infect humans and eating an infected fish isn’t harmful. CPW Whirling Disease Studies The cooperative investigations initiated by CPW have led to the development of several effective control strategies in CPW hatcheries, which stopped the spread of whirling disease through stocking operations. Research continues into protecting uninfected waterways and providing excellent fishing opportunities. These current CPW research projects have shown a great deal of promise: Trout Studies CPW researchers developed rainbow trout strains that are resistant to whirling disease and are evaluating their uses in stocking operations. These strains of fish are able to survive exposure to the parasite. Some of these strains are now produced in CPW hatcheries for stocking. Current evaluations are focused on determining which varieties have the best growth, survival and value for anglers. There is ongoing work to optimize the production of these rainbow trout strains in our state hatcheries. Other disease resistant varieties of rainbow trout are being tested for their ability to reproduce and survive in the wild to re-establish and maintain natural self-sustaining populations. Several locations that were stocked with resistant strains already show evidence of natural reproduction and survival in rivers, including the Gunnison, Arkansas and Colorado. Additional sites are being stocked in coordination with further research and management activities. COLORADO PARKS & WILDLIFE • 6060 Broadway, Denver, CO 80216 • (303) 297-1192 • cpw.state.co.us �Resistant Worm Studies The complex life cycle of whirling disease poses challenges to controlling the spread. The parasite, Myxobolus cerebralis, starts life as a water-borne spore on the bottom of waterways. Small worms, Tubifex tubifex, eat the parasite spores and become infected. The parasite multiplies within the worms. the offspring are released into the water in a microscopic free-floating stage that attaches to fish, infecting them. Recent findings: • Various lineages of worms have differences in susceptibility to whirling disease. Some of these worms are able to eat the whirling disease parasite without becoming infected. Transplanting resistant strains of worms to areas where the susceptible varieties exist may help reduce the level of infection in those areas. • Studies in the Upper Colorado River Basin and Windy Gap Reservoir dating back to 1997 found four lineages of T. tubifex, including three with lesser or no susceptibility to the disease. Ongoing research found that those three lineages have become the dominant varieties in the reservoir while the most susceptible worm lineage has declined to less than 15 percent of the population. There’s no known cause for the shift, but CPW researchers are continuing their work. Whirling Disease Life Cycle Myxobolus cerebralis Young rainbow trout Infected adult brown trout Ongoing Prevention Strategies CPW researchers worked with wildlife managers and other agencies to develop prevention strategies that are used successfully throughout Colorado to control the spread of whirling disease into additional waterways: • Protocols to keep hatcheries disease free, including periodic testing and installation of ultraviolet lights at one hatchery to kill whirling disease spores. • Policies to protect uninfected streams and rivers from receiving stocking fish from infected hatcheries.

Although WWPs provide economic and recreational benefits for local communities (Hagenstad et al. 2000; Loomis and McTernan 2011), they may have unintended impacts on instream biota and stream functions, particularly when the hydraulic conditions formed by the WWP are different from those naturally found in the surrounding river. The impact of WWPs on habitat connectivity and instream habitat quality have been the focus of several recent studies. Although these studies have primarily focused on fish passage and habitat, impacts to aquatic insects and sediment transport may also occur at WWPs. Fish Passage Impacts The elements that create a desirable surf wave (increased velocity, decreased depth, a hydraulic jump, and a stable, often grouted stream channel) create conditions that can impede fish movement. Swimming speeds and jumping ability vary greatly between fish species. Suppression of upstream trout movement has been documented at WWP structures, but the degree of impact varied by fish size and characteristics of the individual structure (Stephens et al. 2015; Fox et al. 2016). As trout are among the strongest swimming and jumping fish species in Colorado, small-bodied and weaker-swimming fish native to Colorado streams are even more susceptible to habitat fragmentation associated with WWP development. Brown Trout Mottled Sculpin Fish Habitat Impacts Although WWPs create deep pools, observed fish densities were significantly higher in natural pools than in WWP pools (Kolden et al. 2015; Kondratieff et al. in preparation). Habitat degradation in WWPs was associated with the unnatural hydraulics created by the recreational features and conversion of riffle habitat to drops over the wave structures. Design Guidelines CPW recommends that adequate environmental safeguards be included in the design and construction of WWPs to ensure that stream functions, fisheries, and recreational fishing are not adversely impacted. Each structure must be examined on a case-by-case basis, and monitoring and adaptive management should be included in the proposed project budget. COLORADO PARKS & WILDLIFE • 1313 Sherman St., Denver, CO 80203 • (303) 297-1192 • cpw.state.co.us �Site Selection   Design and construction of WWPs should preserve the natural aesthetic qualities of the river. WWPs should be located in degraded reaches when possible and should aim to improve the natural functions of the reach rather than maintain degraded conditions. WWPs should not be constructed in natural, un-modified river channels (American Whitewater 2007). WWP sites should be selected to minimize recreational conflicts with anglers. There is increased potential for boaters to displace anglers at WWP sites, especially during the summer months. If WWP construction affects a popular fishing location, mitigation such as new fishing access or habitat improvements should be considered. Ecological Design Considerations       WWP structures must be designed to allow upstream fish passage for all life stages of native and sport fishes present throughout the annual hydrologic cycle. Fish passage is dependent on water velocity, water depth, vertical height of structures, linear distance of the passage corridor, surface roughness, and attraction flow. Hydraulic characteristics at WWP features generally conflict with ideal conditions for fish passage. Therefore, a fish passage channel separate from the WWP structure may be necessary. The passage channel should meet hydraulic design criteria for target species across a range of flows. Hydraulic modeling of the proposed structure should be conducted during the initial design phase to evaluate potential impacts to fish passage and habitat. Streambed and bank disturbance due to construction activities should be scheduled for a time of year when egg incubation is not occurring. An increase in fine sediment to the stream during incubation can suffocate developing embryos. Erosion control and revegetation plans utilizing native riparian species should be required for each project. WWP structures should not cause sediment deposition upstream or downstream of the structure. Sediment deposition can eliminate fish and benthic macroinvertebrate habitats, create favorable conditions for the spread of whirling disease in trout, and increase flooding risk if sediment deposition decreases channel capacity. Recreational In-channel Diversion (RICD) water rights can be acquired for WWPs to provide recreational experiences in and on the water. These protected flows should be managed to benefit boating recreation as well as conservation and management of native and sport fish. Flows deviating from the natural flow regime, such as water calls during spawning periods, could have adverse impacts on stream ecology (Poff et al. 1997). References American Whitewater, 2007.

Construction of the CRCC around Windy Gap Reservoir will allow fish movement and provide access to favorable habitats, such as optimal spawning locations, that have been previously unavailable to populations upstream and downstream of the reservoir. The primary objectives of the study are to evaluate fish movement patterns prior to the construction of the CRCC, and that the CRCC is being used for fish passage after construction. Evaluations are taking place on Northern Water, City of Granby, and private properties above and below Windy Gap Reservoir. To accomplish this, the fish movement study involves collaboration between these entities, as well as CPW aquatic researchers and biologists, Trout Unlimited, and Grand County Learning by Doing. Population Estimates and PIT Tagging Population estimates conducted in 2020-2022 provide baseline data on fish populations, and allow researchers to monitor and compare changes in these populations before and after construction of the CRCC. These estimates also allow opportunities to tag fish with Passive Integrated Transponder (PIT) tags used to evaluate fish movements. PIT tags use the same technology as those commonly used to identify pets, providing a unique ID for every fish that is detected by an antenna. PIT-tagged fish were released annually in the fall at two sites in the Colorado River and two sites in the Fraser River above Windy Gap Reservoir. Additionally, PIT-tagged fish were released in the spring throughout a four-mile stretch of the Colorado River below Windy Gap Reservoir. Since the study began in 2020, 4,234 fish have been PIT tagged in the Colorado and Fraser rivers, including 3,138 Brown Trout, 611 Rainbow Trout, 6 Cutbows (hybrids of Cutthroat Trout and Rainbow Trout), and 479 Mottled Sculpin. Mottled Sculpin are currently absent downstream of Windy Gap Reservoir. The CRCC is intended to facilitate sculpin distribution, increasing the diversity of the Colorado River downstream of the reservoir. Left to right: 32-mm PIT tag for evaluating Brown Trout and Rainbow Trout movements in the Colorado and Fraser rivers; 12-mm PIT tag being inserted into a Mottled Sculpin; paired stationary antennas installed on the bottom of the river used to evaluate directionality of movement; antenna station containing readers for recording tags as they pass stationary antennas; mobile antennas deployed in the Fraser River. COLORADO PARKS & WILDLIFE • 317 West Prospect Road, Fort Collins, CO 80526 • (970) 472-4436 • cpw.state.co.us �Monitoring Movement with Stationary and Mobile Antennas Movements of PIT-tagged fish are passively monitored using two stationary antenna sites in the Colorado River below Windy Gap Reservoir and one stationary antenna site at the confluence of the Colorado and Fraser rivers above Windy Gap Reservoir. Paired antennas were installed on the bottom of the river to allow researchers to determine direction of movement, depending upon which of the two antennas a fish passes first. The antennas are connected to readers that store the date and time for every tag detected and are operated continuously 24 hours a day, 365 days a year. Antennas constructed in the bottom of rafts use GPS sensors to actively locate PIT-tagged fish in the Colorado and Fraser rivers in April, July, and October. These mobile antennas allow researchers to determine the location of sedentary fish such as Mottled Sculpin or certain age classes of Brown Trout and Rainbow Trout that move shorter distances, making it less likely that they would be detected as a stationary antenna site. Data collected by the stationary antennas have provided some valuable insights into fish movement within the study area. Generally, fish move more often at night than during the day, especially Brown Trout, likely to avoid predators. Brown Trout and Rainbow Trout exhibit seasonal movements concurrent with their spawning seasons, Brown Trout in the fall and Rainbow Trout in the spring. Movement distance and timing is also dependent on fish size. Mottled sculpin do not exhibit seasonal movements, but rather move sporadically throughout the year. Visualizing the Data Maps such as this one depicting tagged fish release sites in colored stars and the location of fish from those release sites in the same colored circles allow researchers to draw conclusions about the distances fish have moved and overall movement patterns of the populations as a whole. Using data obtained from the mobile antenna surveys, we have seen that, upstream of Windy Gap Reservoir, some fish released in the Fraser River moved into the Colorado River, and vice versa, and that long distance movements are made in the Colorado River below Windy Gap Reservoir during certain times of year. Data collected from the stationary antenna sites, mobile antenna surveys, and recaptures of tagged fish during the population estimates will be used to obtain estimates of detection, survival, and movement probabilities, by species and fish size, before and after construction of the CRCC.

While most activities focus on hunting, fishing and wildlife viewing, each SWA has different permitted activities, based on location and available resources. These parcels of SWA land are paid for primarily by sportsmen and managed for the benefit of wildlife. CPW manages about 769,000 acres of land within 348 SWA lands around the state. SWAs range in size from just a few acres to several thousand. In general, there is no access fee to utilize a SWA. Since many SWAs are managed for wildlife and wildlife habitat, seasonal closures may limit public access. CPW encourages people to check online or check the Colorado State Recreational Lands brochure for the specific regulations of SWAs. (cpw.state.co.us/Documents/RulesRegs/Brochure/lands.pdf) State Fish Units There are 18 state fish units (SFUs) around Colorado that offer limited public access. SFUs include fish hatcheries like Durango and rearing operations like Chalk Cliffs. Although the primary purpose of a SFU is the hatching and rearing of stockable fish, SFUs do allow self-guided tours and a few offer limited wildlife recreation. © WAYNE D. LEWIS, CPW State Trust Lands The State Land Board (SLB), an agency within the Colorado Department of Natural Resources, owns and manages approximately 3 million acres of state-owned land commonly referred to as State Trust Land. These properties were set aside at statehood for the specific purpose of generating revenue and providing on going support for Colorado public schools and other public institutions. Because these are working lands, State Trust Land is generally closed to the public. In 1993, CPW entered into a long-term lease agreement with the SLB to provide limited sportsmen access on approximately 500,000 acres of State Trust Land. Through the program, sportsmen may enjoy a variety of wildlife-related uses including hunting, fishing and wildlife viewing. Opportunities vary among properties, as do rules and regulations for authorized use. Currently, there are 241 STL parcels providing almost 490,000 acres of wildlife-related recreational access. (cpw.state.co.us/Documents/RulesRegs/Brochure/lands.pdf) 1 This includes Lone Mesa State Park which is currently open for limited big-game hunting opportunities through a special permit 2 Access permitted only with a limited number of big-game hunting licenses acquired through the limited draw process © WAYNE D. LEWIS, CPW State Wildlife Areas �Walk-In Access Program The Walk-In Access (WIA) program is designed to open privately owned land to public small-game hunting by entering into public access agreements with landowners willing to allow public hunting. Each year, CPW holds an enrollment period for landowners to offer their land into the WIA Program. CPW then inspects the land and either accepts or rejects it based on its value for hunting. All properties that are accepted into the program are published in the regular Walk-In Atlas (late August) or the Late Cropland Walk-In Atlas (late October) brochures. Enrolled lands are posted with WIA boundary signs so that hunters can clearly identify properties that are open to WIA hunting. In 2015, CPW enrolled almost 200,000 acres in the WIA program. A small-game license is required to utilize a WIA property as small-game hunting is the only allowable use of WIA properties. Locations of WIA properties can be found in the Small Game Walk-in Atlas or the Late Croplands brochure.

State parks offer a variety of activities such as boating, hiking, fishing, hunting, camping and more. Colorado’s state parks are open every day of the year. All state parks require an entrance fee. Daily passes range from $7 - $9 and an annual park pass is $70. Thirty-four parks offer camping at over 4,000 campsites and 58 cabins and yurts. Many state parks are built around a lake or waterway, which means boating, fishing and other water sports are among the headliners. In addition to water sports, over 700 miles of trails offer recreational activities for many park users. Limited hunting opportunities are available on many state parks.

The program provides Colorado residents a unique opportunity to hunt on private ranchland that would normally be closed to the public. Participating ranches provide public hunting recreation access to their land free of charge to those who draw licenses. Public licenses on each ranch are available through CPW’s draw process. The number of licenses on each ranch is determined by negotiations between the landowner and CPW. Currently, 29 ranches provide over 1.2 million acres of hunting access to Colorado residents who draw one of these limited licenses.

The Daphnia waterflea was introduced from the aquarium trade and fish stocking. They are native to Africa, Asia and Australia. Like invasive mussels, the Bythotrephes and Ceropagis were introduced into the Great Lakes from ships' ballast water coming from Eurasia. Unlike the fleas dogs are known to carry, waterfleas are very different. They do not live outside the water, and do not bite or harm people or pets. Locations in Colorado: • Bythotrephes longimanus (spiny): no known • Ceropagis pengoi (fishhook): no known • Daphnia lumholtzi: Chatfield State Park, Douglas Reservoir, John Martin State Park, Navajo State Park, Pueblo Lake State Park and Pueblo State Hatchery Identification: • Unique body shape: distinguished from other zooplankton by its long tail (70% of body is tail) • Depending on age – the spine may contain 1-4 barbs (the older the water flea the more barbs) • Head is mostly a single large black eye • Swimming antennae propels flea through the water, allowing travel between shallow and deeper waters. • Range in length from 0.4 to 1.6 mm, depending on sex (females are larger) and age Biology: • Found mostly in temperate freshwater lakes, can tolerate brackish water • Most abundant in the summer and fall • Can tolerate temps between 4º-30º C (39º-86ºF) and .04 to 8% salinity • Both sexual and asexual life cycles, depending on environmental conditions • Less than two weeks per generation with asexual life cycle • Resting eggs may lie dormant for long periods of time, allowing the spread of these exotics into different bodies of water • Resting eggs may also pass, unharmed, through the digestive tracts of fish Bythotrephes longimanus (Spiny) Pathway of introduction and spread: • Eggs and adults are easily transported in: ballast tanks, bilge water, bait buckets, live wells, and on fishing lines, anchor lines, and nets • It only takes one adult or egg to start an infestation • If female waterfleas die out of water, under certain conditions they produce eggs that resist drying and freezing, which can establish a new infestation later Negative impacts: • Outcompete native juvenile fish for food, causing low survival rates, and because barbs stick in throat, are unpalatable to juvenile fish • Avoid predation by larger fish by retreating to deeper waters during the day (10-20m) where they are less visible and ascending (0-10m) at night where food is abundant and temperatures higher, increasing metabolism and growth rates • Their long spines can cause them to become entangled on fishing lines and can clog eyelets of fishing rods Management: Once waterfleas are established, they are almost impossible to eradicate. Educating the public and following state watercraft inspection and decontamination procedures are the best methods to contain current infestations and prevent further spread to new waters. Prevention: Preventing the spread of invasive waterfleas is the best strategy; here is what you can do: • CLEAN all plants, animals and mud from your fishing gear, boat, trailer, and equipment before leaving the water. Clean your boat, tackle, downriggers, trailer, waders, etc. with hot water (above 120ºF) when you get home • DRAIN live wells, ballast and bilge water before you leave the water body • DRY boats and equipment to dry completely before launching in other waters • DISPOSE of unused bait in the trash, not in the water Ceropagis pengoi (Fishhook) Images courtesy of Michigan Dept. of Environmental Quality Daphnia lumholtzi COLORADO PARKS & WILDLIFE • 6060 Broadway, Denver, CO 80216 • (303) 297-7295 • cpw.state.co.us � Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

The Act defines ANS as exotic or nonnative aquatic wildlife or any plant species that have been determined to pose a significant threat to the aquatic resources or water infrastructure of the state. The Parks Board passed regulations required by the Act on February 20, 2009 and updated them since that time. The regulations require mandatory watercraft inspection, and if necessary, decontamination of all boats coming from out of state, leaving waters with known ANS and boats entering high-risk waters where inspections are required by the managing entity. The focus of the program is to prevent zebra and quagga mussels and other ANS from infesting Colorado’s water resources and threatening our water storage and distribution systems for municipal, industrial and agricultural use. The Colorado ANS Program is highly effective and a model which other states across the nation are learning from. Program Goal and Successes The goal of the program is to protect the state’s natural resources, outdoor recreation and water supply infrastructure through the prevention of new introductions of costly invasive species, such as zebra or quagga mussels, in Colorado. Western states such as Arizona, Kansas, Nebraska, Oklahoma, South Dakota, and Texas, do not have mandatory ANS prevention programs and continue to become infested with zebra or quagga mussels. Colorado has prevented the introduction of these awful invasive species due to the diligent efforts of watercraft inspection and decontamination staff, as well as monitoring, education and enforcement actions. There has never been an adult zebra or quagga mussel found in Colorado. Pueblo Reservoir was de-listed in January 2017 following 5 years of negative detections. All other reservoirs that initially tested positive in 2008 were de-listed in 2014 after 5 years of negative testing. CPW’s ANS Program has worked to stop the continued inoculation of our waters to invasive mussels being introduced by recreational watercraft. Sampling and Monitoring Sampling and monitoring is a key component to the success of the ANS Program. CPW has sampled 584 “at-risk” waters over the last decade and it was through this sampling program that invasive mussel larvae were first detected in Colorado. While CPW ANS staff monitors the state’s public waters for numerous invasive plant and animal species, the focus of sampling is on early detection of zebra and quagga mussels. There are three sampling protocols that target the three life cycles of mussels. CPW also documents native aquatic plants, mollusks and crayfish while performing monitoring activities for invasive species. Colora d o Pa r ks & Wi ldlife Protect Colorad o’s Lands and Wate rs Learn How You Can Stop InvaSIve SpeCIeS Information and Outreach CPW and its partner agencies have implemented a comprehensive, multifaceted invasive species public education campaign. Accomplishments include distribution of tens of thousands of printed rack cards, brochures, handouts, DVDs and posted signage at offices, boat ramps and other public access points. Additionally, a media relations campaign has been launched using web, radio, print and television. www.cpw.state.co.u s Working Together: Watercraft Inspection and Decontamination (WID) Watercraft inspection and decontamination is a requirement of the ANS Act and continues to be a key component in preventing the spread of ANS into and within Colorado. CPW coordinates the vast network of WID stations that are operated by CPW, the National Park Service, Larimer County, various municipalities and private industry locations. In total, the state has collectively performed over 4.9 million inspections and 119,814 decontaminations since 2008. cpw.state.co.us �2018 Water Resources Development Act The 2018 Water Resources Development Act (S. 3021) was passed by the 115th Congress and signed into law last October. Section 1170 includes a provision which directs the U.S. Army Corps of Engineers to establish, operate, and maintain new or existing watercraft inspection stations to prevent the spread of aquatic invasive species in the Columbia, Upper Missouri, Upper Colorado, South Platte and Arizona (should be Arkansas) River Basins. The provision also authorizes the Army Corps to assist states with monitoring and rapid response efforts in the case of an infestation of quagga or zebra mussels. Green Mountain Reservoir In August 2017, the U.S. Bureau of Reclamation (BOR) detected quagga mussels in Green Mountain Reservoir. The specimen were genetically confirmed to be quaggas by an independent lab for CPW. Rapid Response was initiated by CPW and began immediately among the multi-jurisdictional partnership. Green Mountain is now listed as “suspect” for quagga mussels and containment is ongoing. Resources are needed for infrastructure, security and staffing to prevent the spread through watercraft. Green Mountain Reservoir within Summit County is owned by the BOR as part of the Upper Colorado River Collection System, and is managed for recreation by the White River National Forest. There were no detections in either 2018 or 2019. If there are no detections in 2020, the reservoir will be de-listed in 2021 per regional standards. Mussel Boat Interceptions Infested mussel boat interceptions continue to skyrocket each year. In total there have been 281 watercraft intercepted with adult zebra or quagga mussels attached since the ANS program began. In 2019, CPW intercepted 86 watercraft infested with zebra or quagga mussels coming in from out of state. In 2018, the state intercepted 51 and in 2017 the state intercepted 26 infested watercraft. This exponential growth in infested boat interceptions is directly related to the growing threat invasive species pose to water infrastructure, natural resources and outdoor recreation. The majority of the intercepted vessels were coming from Lake Powell, the State of Arizona or the Great Lakes. All boats were decontaminated to ensure all mussels were dead, and no mussels were visibly attached. An administrative solution in both the House and Senate is needed to correct the typo is Section 1170 from the nonexistent Arizona River Basin to the Senate’s intent of providing resources to the Arizona River Basin with its headwaters in Colorado. Urge the Army Corp to not delay appropriations or planning in the Upper Colorado or South Platte Basins while the Arizona/Arkansas Basin typo is corrected. Support is needed to gain the fiscal appropriations as authorized in the bill. The Stop the Spread of Invasive Mussels Act of 2019 Senator Bennet, along with Senator Daines and Senator Tester from Montana, introduced the Stop the Spread of Invasive Mussels Act of 2019. The bill authorizes the Secretary of Interior through the Commissioner of Reclamation to provide financial assistance to states or local governments for WID. The bill adds several federal agencies, such as the National Park Service, as a member of the ANS Task Force and provides authorization for all members of the ANS Task Force to conduct WID into and out of federal waters. The bill requires the ANS Task Force to report back on any regulatory changes necessary to implement WID prevention or containment. Finally, the bill corrects the typo in Section 1170 of S.3021 to authorize the Arkansas River Basin. Sponsorship and support is needed to pass this bill. The threat of invasion from zebra and quagga mussels is greater than ever due to numerous new infestations in surrounding states such as Arizona, Kansas, Nebraska, North Dakota, Oklahoma, South Dakota, Texas and Utah. Operating and Financials The Supreme Court ruling in case 13SC996 significantly reduced the source fund for the ANS Program (Tier II Severance Tax) as appropriated in the ANS Act. A broad stakeholder effort was called upon to raise funds and determine long term solutions. CPW redirected agency cash and a USFWS Motorboat Colorado Grant to pay for the 2017 boating season, along with over $1M of partnership funds. The Colorado General Assembly provided funding to the ANS Program through SB17-259 and HB18-1338 to be leveraged with federal dollars and other sources to maintain the program over the 2018–2019 boating seasons. In 2018, the Colorado General Assembly passed the Mussel Free Colorado Act (HB18-1008) to provide a new stable funding source through the creation of an ANS stamp for motorized boats and sailboats—$25 for in state residents and $50 for out of state visitors. The ANS Stamp will provide approximately $2.4M (50% of the need) annual funding to the ANS Program. The bill also increases fines for violations and allows CPW to recoup costs for decontamination of quarantined and impounded vessels. Similar to the 2017 joint resolution on ANS which passed the State Legislature unanimously, the Mussel Free Colorado Act continues to encourage federal governments, specifically the Bureau of Reclamation, U.S. Forest Service and Army Corp of Engineers, to provide the other half of the needed funds for the ANS Program since many of the highest risk waters are federally owned or managed reservoirs. How You Can Help • Contact U.S. Senators and Representatives, and the U.S. Army Corp of Engineers, and encourage them to secure an administrative solution to correct the typo in Section 1170 of S. 3021 (WRDA-2018) changing Arizona River Basin, which does not exist, to Arkansas River Basin, which was the intent of the Senate. • Encourage Congressional delegates and the Army Corp of Engineers to provide fiscal appropriations under Section 1170 of S. 3021 for the Upper Colorado, South Platte and Arkansas River Basins. This funding will be used to provide cost share for WID staff, operations, infrastructure improvements, monitoring and rapid response. • Support the passage of The Stop the Spread of Invasive Mussels Act of 2019. • Urge the U.S. Bureau of Reclamation and the U.S. Forest Service to provide funding to CPW for WID staff, operations and improved infrastructure on waters under their ownership or recreational management. • Inform municipal government, county commissioners, state legislators and federal congressional delegates of the potential economic and social impacts that could occur without ANS preventative measures.

Rocky Mtn. Population) ASSESSING HABITAT QUALITY FOR PRIORITY WILDLIFE SPECIES IN COLORADO WETLANDS appears to be the main cause of declines, especially in the Southern Rocky Mountain population. © BRAD LAMBERT, COLORADO NATURAL HERITAGE PROGRAM Species Distribution Range Historically, the Southern Rocky Mountain population of boreal toads occurred in Colorado, New Mexico, and Wyoming. Once considered common, boreal toad populations declined sharply in Colorado and Wyoming and have not been found in New Mexico since the early 1980s. Boreal toads (Anaxyrus boreas, Family Bufonidae) lay strands of several thousand eggs in shallow ponds. The eggs hatch after two weeks, and tadpoles remain for 60–90 days. Species Description Identification With bumpy green-to-brown skin (occasionally rust or gray) and a thin white stripe along the back, boreal toads look similar to Woodhouse’s toads. Boreal toads occur mostly above 8,000 feet in elevation, whereas Woodhouse’s toads occur mostly below 8,000 feet. Females grow up to 4.3 inches, and males grow up to 3.7 inches. Boreal toads do not have a vocal sac; males emit only a very soft chirp. Preferred Habitats Boreal toads occupy numerous wetland types (emergent marshes, kettle ponds, beaver ponds, streams, lakes, reservoirs, and wet meadows), often surrounded by coniferous forests. Boreal toads travel up to 1.5 miles from their breeding and summer ranges to hibernate in microhabitats that do not freeze, including under logs and rocks, in rodent burrows, chambers beneath large boulders, and beaver lodges. Diet Adult boreal toads consume a wide variety of insects, spiders, and snails. Tadpoles eat organic substances suspended in the water column or on bottom. Conservation Status Federal: Not listed. Colorado: Listed as Endangered, designated Tier 1 Species of Greatest Conservation Need. BLM: Listed as Sensitive Species. USFS: Listed as Sensitive Species. Boreal toad populations have declined for numerous reasons, including diseases, environmental stress to the immune system, ultraviolet radiation, environmental toxins, altered hydrology, and habitat disturbance.

In 2013, we hosted millions of visitor days at 42 amazing state parks, including the brand new Staunton State Park which opened in May. In 2013, we put millions of hunters and anglers into the field across the state. We registered thousands of boats, snowmobiles and off-highway vehicles. We put tracking collars on sage-grouse chicks, researched black bear use of residential areas, followed radio-collared mountain lions on the Front Range, stocked millions of fish statewide, and managed the more than 900 species of wildlife everyone likes to see as part of this great state. We did it all as an enterprise agency that receives no annual funding from the state’s general tax fund. Colorado Parks and Wildlife enters 2014 with a feeling of pride for our past successes. We appreciate the support of Coloradans, the legislature, the outdoorsmen and the outdoorswomen, the adventurers, the visitors and the fans of our amazing natural resources. We say “thank you” to the people who supported the renewal of the Colorado Habitat Stamp in 2013. We extend our deepest appreciation for the thousands of volunteers who have given hundreds of thousands of hours to support our mission. We say “thanks” to everyone who bought a parks pass, a hunting license, a fishing license or registered their boat, snowmobile or OHV. We say “congratulations” to the thousands of people who completed a hunter education class, a boater safety class, learned to camp in the “Let’s Camp” program, or participated in one of the hundreds of outdoor recreation seminars offered last year. To those who didn’t, we say “come join us” and see all that makes Colorado amazing. We are optimistic, yet we are realistic. There are many things on the horizon in 2014 that will require continued support from those who care about what we do at Colorado Parks and Wildlife. We recently wrapped up our “Path Forward” merger report to the legislature and we already have our sites set on a new, more comprehensive strategic plan to guide our agency forward. We’ll keep working to assure that Colorado’s native species avoid expensive federal regulatory intervention. We’ll embark on the process of setting the big game hunting season structure for 2015-2019. We will work to make sure that recreation and wildlife are rightly considered as Colorado undertakes water strategy planning. We will work to implement the strategies of the 2014 Statewide Comprehensive Outdoor Recreation Plan (SCORP). There is work to be done and Colorado Parks and Wildlife is in motion.

Seventeen positions in the agency have been eliminated including engineering, education, watchable wildlife, and research of species such as mule deer, native fish and boreal toads. While no one likes to tighten their belt when tough budget decisions have to be made, the Colorado Parks and Wildlife staff made the difficult decisions to recommend a package of reductions that will make sure that Colorado Parks and Wildlife can face a brighter future and continue the positive work that is laid before us. Partnering for habitat and recreation Did you know that much of the most important wildlife habitat in the state is on private land? In fact, about 95 percent of the critical winter range for mule deer is in private ownership. From pronghorn to prairie chicken and burrowing owls to badgers, there are many species that are almost fully dependent on private lands. With the continued support and cooperation of private landowners - from farmers and ranchers to energy companies - Colorado Parks and Wildlife is making positive strides to protect important habitat. © CPW 42 S� tate Parks 23 Recreational/Water-based Parks 16 Resource-based Parks 3 River Corridor Parks Financially sound into the future This year, Colorado Parks and Wildlife will begin reducing agency expenditures by $9.9 million per year. That’s some tough cuts across the agency but they’re necessary cuts to make sure that the agency and its mission are protected for future generations. CPW Land and Water Acres Ownership and Management as of 7/1/2013 State Parks Properties © CPW Adventure seekers from across the globe flock to Colorado for its rugged mountains, majestic wildlife and amazing places but we aren’t just the dream destination for the hard core and extreme thrill seekers. We are the beginning of the experience for anyone looking to do more, see more, be more and feel more. Through the use of conservation easements purchased from and donated by willing private landowners, Colorado Parks and Wildlife has protected hundreds of thousands of acres of wildlife habitat. It has been done in a way that keeps traditional uses like farming and ranching on the land. Much more habitat has been protected by agriculture and landowner groups and by individual landowners who have enhanced habitat through their own efforts. Programs like the Walk-In Access Program and access easement opportunities make it possible for private landowners to find new revenue streams that can make a difference to a family’s bottom line. From a listing on the Colorado Birding Trail to participation in a wildlife viewing event, many private landowners are also learning the financial rewards that come with being part of the state’s $2.2 billion annual watchable wildlife industry. �The Habitat Stamp: Small stamp, big difference When the sky opened up and dropped record rainfall in northeastern Colorado in September, Colorado Parks and Wildlife staff rushed to help. CPW swift water rescue teams deployed to the area and agency staff, with their boats, trucks and equipment converged to help with rescue efforts and to protect evacuated neighborhoods. While all of that occurred, our properties were not without their own challenges. St. Vrain State Park suffered significant damage and was closed throughout the fall and winter (expected to reopen spring 2014). Eldorado Canyon State Park - one of the world’s best known technical rock climbing areas - lost a main road, picnic areas and the park was shut down for weeks. Dozens of state wildlife area properties along the South Platte River were damaged and many were permanently changed as the power of nature pushed through the countryside. © CPW The Colorado Wildlife Habitat Stamp continues to make a big difference. As a testament to that difference, in 2013, the Colorado legislature approved a renewal of the program through 2026. Conservation easements purchased through the program have protected more than 150,000 acres of important habitat so far in the state - keeping agricultural land in the hands of the private land stewards who know it best. In addition, the Habitat Stamp is responsible for opening up access to some great places to hunt and fish. Flood damages parks and properties: GOCO invests in Colorado © CPW Great Outdoors Colorado invests a portion of Colorado Lottery revenues in parks, trails, wildlife habitats, river corridors, playgrounds and open spaces in all 64 counties. Voters approved a constitutional amendment to create GOCO, which is managed by an independent board and uses no tax dollars. Half of GOCO funds, or more than $400 million to date, is dedicated to Colorado Parks and Wildlife projects. The list includes building and enhancing parks, trails and facilities; providing water for recreation, preserving natural areas, and protecting wildlife species; funding for Youth Corps crews, and support for environmental educational programs, volunteer programs and youth outreach. In 2013, CPW opened FY 12-13 Award Staunton State Park thanks Parks Purpose $11,553,600 to $10 million in GOCO Wildlife Purpose $18,847,618 investments in land acquisition and infrastructure Lottery (Parks) $13,563,176 development. CPW merger brings convenience © CPW Colorado Parks and Wildlife was created in 2011 when Colorado State Parks and the Colorado Division of Wildlife were merged through legislative action. Today, the merger means more convenience for the customers of the agency. Need a park pass or boat registration? Now you can do that at 18 more offices around the state. Need to get a hunting or fishing license? Now you can buy it at 42 state parks. And there are more conveniences to come in 2014 as a new agency website launches and new programs are offered at locations across Colorado.

Funded primarily through user fees, Great Outdoors Colorado (GOCO) grants, and federal and state grants, CPW strives to ensure efficient and effective use of financial and human resources. Through planning and by following Colorado's Lean Program, CPW evaluates programs and makes spending adjustments accordingly. In fiscal year 13-14, CPW invested a portion of its reserve funds to help rebuild habitat and infrastructure after unprecedented flooding. CPW also provided local grants for trails, improved wildlife habitat, successfully worked with the public to develop a 5-year Big Game Season Structure and collaborated with partners to provide outdoor experiences for youth and families, to name a small fraction of accomplishments. Wildlife and outdoor recreation represent an important part of Colorado’s economy and quality of life, accounting for an estimated $34.5 billion in total economic significance. Hunting, angling, wildlife viewing and state park visitation contributes roughly $6.1 billion in economic effects statewide. Through ongoing partnerships, strategic planning and wise resource investments, CPW is poised to continue providing quality wildlife management and outdoor recreation during the coming year. 5% Sale of goods, donations, interest and other revenues: 4% 41% 3% Severance tax and General fund¹: License sales and other wildlife fees: Reserve funds: $8,735,560 $80,248,080 $9,653,867 $4,963,054 15% Park entrance and camping fees, reservations and registrations: 16% $28,370,985 Lottery and Great Outdoors Colorado: 16% $31,596,886 Federal and state grants: $30,672,308 Total Revenue (FY 13-14) $194,240,740 ¹CPW received $471,773 from GF in FY13-14 (0.2% of total revenue) Total Expenditures (FY 13-14) $194,240,740 9% Capital improvements/ equipment: $17,873,872 30% 1% Operating expenses: Land and water acquistion: © CPW/VERDON TOMAJKO $56,860,112 $2,659,424 6% 8% 46% Grants to others: Payments to other agencies: Personal services: $13,429,600 $14,820,921 $88,596,811 cpw.state.co.us �Colorado Parks & Wildlife Facts and Figures Economic Significance of Outdoor Recreation Total Economic Effect² All outdoor recreation activities³ $34,505,000,000 Highlighted activities Fishing⁴ $1,916,000,000 Hunting⁴ $919,000,000 State park recreation⁵ $1,032,000,000 Wildlife watching⁴ $2,280,000,000 CPW Land and Water Acres Ownership and Management as of 7/1/2014 Jobs 313,000 State Parks Properties Acres 43 �state parks⁸ 16,413 10,882 220,385 Ownership⁹ % of Total Acres Colorado Parks and Wildlife (Fee Title) Non-fee title TBD 19,541 22% 78% ⁸This includes Lone Mesa State Park that is currently open only for limited hunting access. ² This includes estimates of all direct, indirect and induced contributions. ³ This includes a broad set of outdoor recreational activities performed on state, federal, county, local and other lands. ⁴ Source: Economic contributions of Outdoor Recreation in Colorado, 2014, Southwick Associates and CPW. ⁵ �Estimated with visitor expenditure data taken from the 2009 State Parks Market Assessment Study (Corona Research) and a conservative industry economic multiplier.

Park rangers, volunteers and partners provide classes on safe boating practices, beginning hunting and fishing clinics and wildflower identification to name a few examples. This past year, active duty military and veterans could enter any Colorado state park in August for free. Over 6,600 people took advantage of this exciting opportunity. CPW manages the largest elk herd in North America, with an estimated population of 264,000 animals. This elk herd provides hunters with healthy locally sourced food. Additionally people from around the world enjoy watching elk in their natural habitat. CPW also stocks more than 90 million fish throughout the state from 19 state fish hatcheries and rearing units. Coloradans have fishing access to over 2,000 natural lakes, 800 reservoirs and 9,500 miles of streams. © CPW/WAYNE D.

Value is what you get.” — Warren Buffett. Sportsmen and women provide 80 percent of Colorado Parks and Wildlife’s (CPW) funding for wildlife through hunting, fishing and recreational shooting. As Warren Buffett might say, the price of buying a hunting or fishing license corresponds to the value received. CPW finds it increasingly difficult to provide the value sportsmen expect for the prices being paid. The last price increase for resident licenses was in 2005. Since that increase, the costs of doing business have climbed while revenues from resident licenses have remained unchanged. We cut $40 million from the wildlife budget and defunded 50 positions in order to keep our costs down. Without increased revenue, CPW will have to continue scaling back wildlife management and conservation in Colorado, impacting wildlife and the quality of outdoor recreation. That’s why in 2016, CPW held 18 public meetings across the state asking for input on the price of resident hunting and fishing licenses. More than 85 percent of meeting attendees voiced support for a resident license fee increase. Future conversations between CPW and sportsmen and women will focus on how to best fulfill CPW’s mission to perpetuate the state’s wildlife resources. By state and federal law, funding sources for wildlife are kept completely separate from parks funding. The cost of doing business in state parks is also rising. The Colorado Parks and Wildlife Commission is authorized to adjust park pass and camping fee prices but that authority is constrained by a statute that limits the amount of total revenue parks fees can generate. An increase in the sales of parks passes caused revenues to meet that cap. As a result, even though state parks are facing rising costs and increasing pressure to accommodate more visitors, the Commission cannot raise fees to cover these costs. Commission authority to set park fees is set through the legislative process. CPW is communicating with our partners about the situation and discussing opportunities for the future. Preserving the Commission’s authority to set fees puts CPW in a better position if we need to bring in more revenue to meet demand and keep pace with the rate of inflation. Bob D. Broscheid, Director Colorado Parks and Wildlife Charlie Meyers State Wildlife Area Roxborough State Park Bull elk cpw.state.co.us PHOTOS BY © WAYNE D. LEWIS/CPW Let’s keep working together to overcome financial challenges and conserve Colorado’s beautiful places and wildlife. �CPW Adopts New Principles on Conservation and Outdoor Recreation These principles provide an opportunity to unite Coloradans on the importance of our natural resources, and our responsibility to one another in promoting and protecting them. Colorado became the first state to adopt the principles at the November meeting of the Parks and Wildlife Commission. 5. 6. We believe the uniquely American public-land heritage is a privilege and a birthright, and Colorado’s abundant open space and outdoor recreation opportunities contribute to our quality of life and economic vitality. Combined with the North American Model of Wildlife Management and private-land conservation, Coloradans and our visitors enjoy spectacular landscapes in which to work, play and live. 2. 3. 4. Outdoor recreation and conservation require that a diversity of lands and waters be publicly owned, available for public access and cared for properly. Within Colorado’s diversity of land and waters, private land provides a balance of conservation and access for outdoor recreation and conservation of landscapes. Both recreation and conservation are needed to sustain Colorado’s quality of life. Both are beneficial to local economic well-being, for personal health and for sustaining Colorado’s natural resources All recreation has impact. Coloradans have an obligation to minimize these impacts across the places they recreate and the larger landscape through ethical outdoor behavior. Parks have implemented numerous cost-saving measures to stretch existing budgets, such as installing energy efficient lighting and compacting trash to reduce waste disposal costs. © WAYNE D. LEWIS/CPW 1. 7. Proactive management solutions, combined with public education, is necessary to care for land, water and wildlife, and to provide the protections needed to maintain quality recreation opportunities. Physical, biological and social science must inform the management of outdoor recreation. Stable, long-term, and diverse funding sources are essential to protect the environment and support outdoor recreation. Did you know? The CPW outdoor recreation annual impact in Colorado is $6.1 billion. $1 Billion $919 Million Hunting and wildlife viewing are the only recreational activities that benefit every county in the state — urban and rural. Legislative Bill Introduced In order to sustain Colorado state parks and wildlife opportunities, the legislature is considering a bill that would allow the Parks and Wildlife Commission the limited authority to address current financial challenges. Funding is needed to: • • • • • Repair high-priority dams to ensure public safety and maintain recreational opportunities. Address public access for hunting and fishing in Colorado. Increase efforts to improve wildlife habitat. Renovate hatcheries in order to continue stocking reservoirs and streams. Continue inspection programs to keep Aquatic Nuisance Species out of Colorado’s waters. • • Maintain and improve park facilities including trails, campgrounds and visitor centers. Improve outdoor recreation educational opportunities and programs to get more Coloradans outside. Colorado Parks and Wildlife relies on user fees, NOT general tax dollars. However, the fees have not kept pace with operational costs and inflation. • • • • Resident hunting and fishing license fees have not increased since 2005. Park entrance fees have not increased since 2010. Since 2009, CPW has cut or defunded 50 positions and reduced $40 million from its wildlife budget. CPW is facing a forecasted wildlife budget shortfall of $14 million annually just to maintain current operation. © WAYNE D. LEWIS/CPW $1.9 Billion Hunters State Park Visitors © WAYNE D.

New State Trails Plan Colorado Parks and Wildlife will host its first-ever Outdoor Adventure Expo​ Sept. 23-24 at Cherry Creek State Park. This free event invites participants for a taste of the many outdoor recreation possibilities at CPW’s 41 state parks and other properties. From biking to boating, clay pigeons to climbing, the Outdoor Adventure Expo will provide a little something for everyone. Trail use, both motorized and nonmotorized, is the No. 1 recreational activity in Colorado. Each year, Coloradans access trails more than 250 million times.Trails are also Colorado’s top outdoor recreational “gateway” activity. Over the past decade, CPW’s Trails Program distributed more than $54 million for trail grants, capital improvements that benefit trail use and winter trail grooming operations. These funds created job opportunities, especially through the Youth Corp organizations, which received about $1.6 million to build and maintain trails. Strategic Goals: 1. Provide statewide leadership for trail recreation in Colorado. 2. Facilitate trail development and management across Colorado. 3. Serve as the advocate for trails. 4. Emphasize responsible stewardship for all phases of trail development and use. 5. Advance ethical use and cooperation among trail recreationists. 6. Seek financial sustainability for the Trails Program. Discover archery at the Outdoor Adventure Expo. © KEN PAPALEO © WAYNE D.

OUTREACH CONSERVATION Partnering for Conservation Conservation is at the heart of Colorado Parks and Wildlife’s mission. And no other scientific principle is more responsible for creating Colorado’s enormous abundance of fish, wildlife and its world-class outdoor recreation. Yet, in spite of its importance to our state, conservation — in the context of wildlife and outdoor recreation management — is a concept that’s often overlooked and misunderstood. Established in 1897, CPW has a rich history of managing Colorado’s wildlife and recreational resources through conservation science. In fact, CPW’s own mission statement embodies the primary themes of conservation: “The mission of Colorado Parks and Wildlife is to perpetuate the wildlife resources of the state, to provide a quality state parks system, and to provide enjoyable and sustainable outdoor recreation opportunities that educate and inspire current and future generations to serve as active stewards of Colorado’s natural resources.” The new program is a partnership between Colorado Parks and Wildlife, the State Library and local public libraries across Colorado designed to encourage learning at a state park and provide a new unique service offered by the libraries. There are currently 574 backpacks with a free parks pass that are available for check out from 287 libraries statewide. In 2017, Colorado state colleges and university libraries will be included in the program. In a Dec. 2016 library survey, 53 library districts reported 2,671 checkouts in 2016 and there were 454 current holds at the time of the survey for those waiting to check out the program. EDUCATION Check Out Colorado State Parks OUTREACH Whether you’re a hunter, angler, hiker, kayaker or just someone who enjoys Colorado’s wildlife and wild places, here are just a few of the things that Colorado Parks and Wildife is doing to further its mission: Schools and Outdoor Learning Environments (SOLE) The SOLE program started in 2013 as a pilot program through Colorado Parks and Wildlife by funding from Great Outdoors Colorado (GOCO)​with one simple mission — ­ connect kids to the outdoors.

Nationwide, wildlife agencies were created to ensure the prosperity of both game and nongame species. CPW employees are dedicated professionals who work passionately for Colorado’ resources every day. And the agency is fortunate to be supported by dedicated sportsmen and sportswomen who cherish Colorado’s parks and wildlife. Colorado’s natural beauty, land, water and wildlife are the top priorities for the agency. We take our responsibility to operate our 41 state parks — each of which protects valuable landscapes — and to ethically manage wildlife in public trust very seriously. The work of CPW staff is done with dedication and an unwavering sense of duty. Conserving our parks, landscapes, waters and wildlife is a calling for CPW employees. These resources provide a sense of place and purpose for all Coloradans. Not only do we gaze at these natural wonders with awe, we also feel their comforting and healing beauty deep in our soul. When the sun rises on a meadow and the mist lifts, you can hear nature’s song — Colorado’s heartbeat. Our mission underscores the importance of caring for our land, water and wildlife. These natural resources are what makes Colorado special. Not only do these resources perpetuate the intrinsic values of our state’s citizens, they also support a robust economy and our vibrant lifestyle. Assuring the sustainability of our natural resources and the variety of recreation opportunities they provide is vital to Colorado’s future. Hunters and anglers play a major role in sustaining Colorado’s natural resources through their willingness to pay for conservation through the purchase of hunting and fishing licenses. The health and well-being of our land, water and wildlife could not be accomplished in Colorado without the support and investment made by these individuals. Through the support of hunters, anglers, park users and all Coloradans, CPW is working on long-term sustainability for our resources. We cannot predict the future, but are planning for it. Colorado faces a growing number of challenges as we see unprecedented population growth, urban sprawl, habitat loss, continued debates over water use and a growing segment of citizens who are not connected to nature and its care. It is now more important than ever to work together to chart our course in achieving a shared vision and investment in Colorado. We need to rise above our differences to meet the demands of the people and the needs of wildlife. It is on each of us to work on largescale conservation, and to invest in the resources that sustain us. We want to emerge from the challenges stronger and equipped with better strategies to maintain and improve Colorado’s outdoor future. You have entrusted CPW with a very important mission. As the outdoor recreation industry continues to become one of the nation’s largest economic sectors, we must focus on the intersection of conservation and outdoor recreation. We must protect our public lands and ensure the health of our wildlife resources. Despite the challenges we face, CPW remains a leader in outdoor recreation and wildlife management, and we owe a lot of that success to you. Bob D.

Colorado offers numerous opportunities for outdoor recreation and serves a growing and diverse population of people with varied demands for recreational activities. Outdoor recreation at state parks, as well as hunting and fishing opportunities, contribute a combined estimated $6.1 billion to Colorado’s economy. As increasing numbers of tourists and Coloradans take advantage of the state’s outdoor resources, care must be taken to maintain the beauty and accessibility of state parks and the activities therein. GOAL : Increase state park visits. In June 2017, Colorado Parks and Wildlife counted 14.8 million vehicle visits to Colorado’s state parks over the previous 12 months. This was a nearly 10% increase over the prior fiscal year. Based on the last five years, CPW expects 12.8 million state park visitors in FY 2017–18. GOAL: Maintain the number of hunting and fishing participants due to a variety of favorable outside factors including weather and healthy herd numbers. CPW experienced increased participation in 2016 and 2017. Since 1992, Great Outdoors Colorado (GOCO) has awarded more than $​550​million from its share of Colorado Lottery proceeds. $15,250,585 GOCO TO PARKS PURPOSE $15,250,585 GOCO TO WILDLIFE PURPOSE $13,347,498 OUTCOME MEASURE OUTCOME BASELINE (JUNE 2015) ACTUAL (JUNE 2016) ACTUAL (JUNE 2017) OUTCOME TARGET TARGET DATE State park visits 12,272,000 13,515490 14,823,913 12,856,071 2017 Hunting & fishing participants 960,000 1,066,536 1,100,609 960,000 2017 By developing new and maintaining existing trails for the public while conserving wildlife habitat through restoration and improvement projects, Colorado is engaging the next generation of land stewards and protecting the abundant natural resources that make this state so special.

The bill holds us accountable to 10 key goals we plan to work toward addressing by 2025. These goals build off of the agency’s Strategic Plan and long term vision for wildlife and natural resource management. We embrace the goal of stemming the decline of sportsmen and women in our state, and to improve and increase big game populations through investing in habitat and conservation. We hope to begin planning the next Colorado State Park for our residents and visitors. We need to continue recruiting and to retain highly qualified employees to carry out our mission. And we strive to engage all outdoor recreationists in responsibly maintaining and managing the natural resources that make up the very heart of our state. As part of our current generation of stewardship, we want to recognize our hunters, anglers, parks visitors and those purchasing registrations and permits for recreational vehicles. We thank you for your many contributions to conservation in Colorado through those purchases, as your participation in these activities is the primary source of funding in managing the health of our land, water and wildlife. Colorado’s quality of life, outdoor heritage, and economic prosperity are dependent on the health and sustainability of these natural treasures that you help us conserve and protect every day. We are grateful every day for the opportunity to work with, play in and protect the natural resources of Colorado. It takes a lot of hard work to maintain and improve habitat, conserve over 960 species, and manage 41 state parks. But the lands, waters and wildlife that our residents and visitors cherish are equally loved by the hundreds of dedicated CPW professionals that work to ensure the health and prosperity of these resources every day. Looking to the future, we are also extremely thankful for the public support of The Hunting, Fishing and Parks for Future Generations Act. Passed in May 2018, the bill provides the agency with several opportunities to continue working toward our mission, and to address some of the specific challenges that CPW All 10 goals can be found on our website, and we will report our annual progress to the legislature through 2025.

It will be critical for CPW and all partners to share and model the key priorities with their networks, members, staff and all of Colorado’s residents and visitors. �Economic Impact of Outdoor Recreation According to the 2017 Economic Contributions of Outdoor Recreation in Colorado report by Southwick Associates, 92% of Coloradans recreate outdoors. So it may be no surprise that the outdoor recreation industry delivers an economic contribution of $62 billion dollars to the state each year, and accounts for over 500,000 jobs in Colorado. The most popular activities are walking and hiking followed by picnicking, camping and fishing. The staggering popularity of outdoor recreation, and its importance to our economy, means we must all play a role in ensuring we enjoy our outdoors with conservation in mind. Colorado the Beautiful Trail Grants The Colorado the Beautiful Grant Program is a partnership between CPW and Great Outdoors Colorado (GOCO). Over $4 million in grants were awarded to 11 land managers to create or improve trails in Colorado.

Unmanaged plague has the potential to reduce populations of the Gunnison’s prairie dog to the point that a listing as federally endangered or threatened becomes more likely. Such a listing would not only underscore the need for additional conservation, it could also limit land uses for agriculture and recreation. The Gunnison’s prairie dog serves key roles in southwest Colorado’s biological landscapes: • A food source for many wildlife species including raptors and mammalian carnivores. • Prairie dog colonies serve as habitat for mountain plover, burrowing owl, badger, weasel, snakes and other wildlife species. Research Objectives Since the Gunnison’s prairie dog is an important species in the state’s ecosystem, Colorado Parks and Wildlife (CPW) has determined that controlling plague in this species is a priority conservation action. The CPW goal is to develop plague management tools to help manage and stabilize Gunnison’s prairie dog populations on public lands and in cooperation with willing landowners. CPW Plague Control Research Success The U.S. Geological Survey’s National Wildlife Health Center developed a sylvatic plague vaccine (SPV) and tested the vaccine in the lab in 2010. That laboratory research demonstrated that the vaccine is safe and protects prairie dogs from plague. Field trials are necessary to confirm these findings in the wild. In 2012, CPW conducted the first small-acreage field trials of the vaccine to measure prairie dog consumption of the peanut butter-flavored baits, compare the colony population before and after the vaccine, and monitor the prairie dogs responses to the vaccine. Those field tests demonstrated that the prairie dogs readily consumed the baits and the vaccine is safe with no observable negative effects. In July 2013, CPW staff distributed the oral plague vaccine at three Gunnison’s prairie dog colonies in Gunnison and Teller Counties. This began a three-year study to determine if use of the SPV increases or stabilizes survival of vaccinated prairie dogs compared to non-vaccinated prairie dogs. These ongoing research efforts found: • Prairie dogs captured at the treated colonies were tested and, in some cases, 90 percent had consumed the vaccine bait. • The safety of the vaccine and the high uptake rates were also demonstrated when CPW researchers tested the vaccine on a black-tailed prairie dog colony in Larimer County. • Annual use of plague vaccine may be necessary to protect the young animals produced each year. • The oral vaccine research project will continue for two more years (2015) to evaluate impacts on treatment and control colonies. Vaccine baits contain a red dye which marks the prairie dogs that eat them.

COLORADO PARKS & WILDLIFE • 1313 Sherman, Suite 618, Denver, CO 80203 • (303) 866-3437 • cpw.state.co.us �The range of the Gunnison’s prairie dog includes the intermountain valleys and plateaus of Southwestern Colorado. Historic CPW Plague Control Research and Management Plague was found in flea samples collected from prairie dog colonies in northwest Colorado in 2007. CPW responded quickly in 2008, manually dusting white-tailed prairie dog burrows with an insecticide that kills fleas, but is safe for wildlife, in the black-footed ferret recovery area. The treatments were effective at controlling fleas and slowing the spread of plague, and CPW managers expanded the project to protect Gunnison’s prairie dogs while continuing to research and develop additional plague management tools. Starting in 2010, CPW managers dusted Gunnison’s prairie dog colonies in several Colorado counties with insecticide and found that: • There was no observed mortality due to plague in the Gunnison’s prairie dog colonies that were dusted. • Some nearby colonies that weren’t dusted experienced severe population declines due to plague. • Researchers are seeking other more efficient methods to control plague on prairie dog colonies like vaccines. Ongoing Plague Control Research CPW researchers will continue to develop and refine new tools, like vaccines, to manage the spread of plague while using insecticides to stabilize populations of Gunnison’s prairie dogs. Other current projects include: • Testing of new types of baits to efficiently distribute vaccine. • Development of a comprehensive plague control program that utilizes both vaccines and insecticide to effectively stabilize Gunnison’s prairie dog populations. Partners: The U.S. Geological Survey’s National Wildlife Health Center, the U.S. Bureau of Land Management, the City of Fort Collins, the National Park Service, the U.S. Forest Service and many cooperating private land owners. Funding: CPW’s Gunnison’s prairie dog research and management projects are funded mainly through the Species Conservation Trust Fund, which is derived from severance tax revenues on mineral extraction within Colorado. General Plague and Human Health Background The first confirmed human case of plague in Colorado occurred in 1940. Today, plague in humans is rare with an average of seven cases annually in the U.S. Antibiotics are effective for treatment of plague if administered in the early stages of the disease. Gunnison’s prairie dog burrows are “dusted” to kill fleas.

Approval was granted in 2011 to remove individual mountain lions preying on translocated desert bighorn sheep in the Middle Delores River, due west of Montrose near the Utah border. The Commission also approved in 2011 a two-year proposal to remove mammalian predators in the Miramonte Basin, about half way between Telluride and Utah to increase the recruitment of juvenile Gunnison sage-grouse. Finally, approval was granted in 2013 to remove mountain lions preying on Rocky Mountain bighorn sheep translocated to the area of the Hayman burn near Cheesman Reservoir, southwest of Castle Rock. © CPW FILE PHOTO December 14th Commission Meeting in Ft. Collins The purpose of this Commission meeting is to act on CPW’s staff request to approve two predator management research proposals, per the Commission’s 2007 policy on mammalian predator management. Mule deer fawn Mule Deer in Colorado Mule deer are an important wildlife species to the state of Colorado and a large number of communities across the state for a variety of reasons including hunting, wildlife viewing and associated economic benefits. Although mule deer populations are doing well in some areas of the state, their numbers are well below the population objective established for the Piceance Basin, (adjacent to the Roan Plateau – an area with the largest mule deer herds in the state) and also below objective in the upper Arkansas River valley. CPW’s population objective for mule deer is approximately 560,000 statewide; the latest estimate puts the statewide population at under 450,000. CPW is not suggesting that the removal of predators is the solution to increasing statewide deer numbers to 560,000. These two research projects are designed to evaluate the extent to which predation is limiting deer population size in the two specific study areas. © CPW FILE PHOTO In 2013, in response to a continued decline in mule deer numbers, CPW developed the West Slope Mule Deer Strategy. The CPW Commission approved the strategy in December 2014. CPW sought public input to develop the strategy, holding several public meetings across the state facilitated by an independent contractor to ensure objectivity and fairness.

Research projects are compre- Mountain lion hensive, detailed and subject to scientific peer review. The science on the impacts of predators on other wildlife populations is not clear cut or conclusive, contrary to recent claims – CPW would like to make a significant contribution to that body of scientific wildlife knowledge. Science A paper published in 2012 in Mammal Review by Forrester and Wittmer reviewed 48 studies on mule deer survival and predation from the past 30 years and quantified age-specific vital rates, population growth rates and causes of mortality. The authors wrote that: • “The relative contributions of predation, forage availability and weather to observed [deer] population changes remains unclear and controversial” • “Results of predator control studies remain variable” • “Predation was the largest proximate cause of mortality in both adults and fawns in all studies, including in fawns during winter” • “the true effect of summer fawn predation in mule deer dynamics is currently hard to identify” • “Increasing wolf populations in Vancouver Island also caused a decline in high-density black-tailed deer population, and the predator removal study that was conducted was successful in increasing deer populations” • “the role of predation in multi-prey, multi-predator systems at varying deer population densities needs further investigation” Black bear COLORADO PARKS & WILDLIFE • 6060 Broadway, Denver, CO 80216 • (303) 297-1192 • cpw.state.co.us © CPW FILE PHOTO • “suppression of both fawn and adult survival simultaneously from predation and other mortality sources can lead to marked and sustained population declines” �Other Theories Ongoing CPW scientific research in the Piceance Basin has revealed that lack of quality deer habitat is not limiting this mule deer population, contrary to recent claims. The Piceance Basin in northwest Colorado represents winter range supporting the largest migratory mule deer population in the state. This area has been the focus of research and monitoring efforts since the late 1940’s and represents one the best documented mule deer populations in North America. Due to historic mule deer population declines, the Commission reduced total mule deer licenses in the area by 85 percent since 2007 and female licenses specifically have been reduced by about 99 percent; current license allocation in GMU 22 consists of only 590 antlered deer and 20 antlerless deer licenses. Hunting is not the cause of the mule deer population decline. Rationale Based on CPW scientific data, researchers theorize that predation of young fawns in the spring in the Piceance Basin is the limiting factor and CPW proposes to determine if reducing predator numbers in that specific area can result in increased numbers of deer. With regard to the upper Arkansas, managers and researchers theorize that predation of adult does and fawns over the winter months have limited this mule deer population in the past. Since 1999, the leading cause of known mortality on mule deer in the Arkansas Valley has been mountain lions. From 2008 to 2012, higher than normal rates of mountain lion predation were consistent with lower adult survival rates. The exact cause of these elevated predation rates is unknown, but they could be associated with lion harvest quotas not being achieved during this time period. Like the Piceance proposed study area, insufficient habitat is not considered to be a significant factor in fawn survival rates because biologists have only documented minimal numbers of mule deer in these management units dying of starvation or suffering malnutrition. Predation on deer by lions and bears is natural, but today’s ecological systems do not function completely naturally, therefore management intervention is sometimes required to compensate for natural and manmade landscape changes – CPW is not proposing to completely eradicate predators. CPW is regularly called upon to help resolve human‐bear conflicts in Colorado and these conflicts occur to a large degree because of an ever‐increasing number of people which further alters the natural system. © CPW FILE PHOTO Impact Overall numbers of bears and mountain lions in the population units that include the Piceance study area should be minimally impacted (anticipate removing about one percent of the lion population and two percent of the bear population). The predator treatment area represents 6 percent of mountain lion population management unit and 16 percent of black bear population unit. Furthermore, the proposed reductions are consistent with the current mountain lion management objective in this rural area - to maintain relatively low predator densities to reduce livestock conflicts. This area is currently one of four mountain lion population management units (out of 19 lion units statewide) managed to minimize livestock conflicts. Two does COLORADO PARKS & WILDLIFE • 6060 Broadway, Denver, CO 80216 • (303) 297-1192 • cpw.state.co.us �The total number of mountain lions removed during the proposed nine-year upper Arkansas River research project is not expected to differ significantly from the number of lions that hunters would remove from the study area during the same nine-year period if the research proposal was not implemented. If anything, the overall number of lions removed during the study is likely to be lower than what would have occurred by hunting alone. Public Outreach CPW initially proposed the Arkansas River predator management project to the Parks and Wildlife Commission at its meeting in Craig in September 2015. Based on public comment, CPW postponed seeking Commission approval (initially scheduled for the November 2015 meeting in Wray) Black bear to revise the proposal based on public input and to include a second research project in the Piceance Basin. At its June 2016 meeting in Pueblo, the Commission approved a reduction in mountain lion hunting quotas necessary to implement the Arkansas River research project, pending final Commission approval of the research plan at the December 2016 Commission meeting. At its August 2016 meeting in Montrose, the Commission received an update on the timeline for considering the two proposed research projects. CPW also held three public meetings specifically about the proposed research projects in addition to the three public Commission meetings. A meeting was held in Salida on August 15, in Rifle on August 16 and in Denver on September 19. In 2005, the Colorado Division of Wildlife funded a statewide survey of public opinions and perceptions of mountain lions by Corona Research, Inc. Some of the relevant findings were: 88.1 percent supported research to learn more about mountain lion populations Fifty-seven percent of respondents generally believed mountain lions to be common in Colorado A majority (61 percent) of respondents believed mountain lion populations were stable or increasing in size as opposed to declining (22 percent). © WAYNE D. LEWIS © CPW FILE PHOTO Lion and bear populations remain robust in the state ‐ the overall number of lions and bears removed as part of this study is very small when compared to both (Piceance and upper Arkansas) local populations and when compared to populations across the state (statewide lion population estimate is 4,500 ‐ 5,500 and bear population estimate is 17,000 to 20,000).

Moose prefer habitat near lakes, rivers or wetlands, where they feed on young plants including shrubs, aquatic plants, grasses, mosses, willow, and aspen. In 2013, moose inhabited northern forests in 15 states. Twelve states – including Colorado - offered moose hunting. The moose in Colorado belong to the Shiras subspecies, which are smaller than the subspecies found in Alaska and Canada. Colorado’s adult moose can run 35 miles per hour, weigh up to 1,000 pounds and stand six feet tall at the shoulder. History of Moose in Colorado Historical records dating back to the 1850s indicate that moose wandered into northern Colorado from Wyoming, but were transient and never established a stable breeding population. Most of the historic sightings involved hunters seeing and/or harvesting a single bull moose. Moose Reintroduction In the 1950s, Colorado wildlife officials considered bringing moose to the state. There were concerns, voiced at public meetings on a series of proposals, that moose would compete with cattle and sheep on grazing land, and potentially damage local ecosystems and other wildlife species. State wildlife managers advocated moose reintroduction because of the abundant habitat available and lack of natural predators. During the 1960s and the early 1970s, the Colorado Division of Wildlife (now Colorado Parks and Wildlife) worked with the U.S. Forest Service, the Bureau of Land Management, the National Park Service, the general public and local ranchers on selecting the North Park area in the Routt National Forest near Walden as the site for the first moose reintroduction. In 1978, state wildlife experts transplanted 24 male and female moose from Wyoming and Utah to create a breeding population in North Park and provide hunting opportunities. Additional moose from Wyoming, Utah and Colorado’s own growing population were introduced to other areas of western Colorado over the years. The project succeeded in creating new hunting opportunities and a popular wildlife viewing option. The state legislature, in 1995, declared Walden the “Moose Viewing Capital of Colorado.” By 2012, the reintroduction program had established a breeding population of about 2,300 moose in Colorado. Moose hunting is available in 39 game management units (GMUs). There were 16,500 applicants for 219 moose hunting licenses and 185 moose were harvested in 2012. While the moose population in other states has declined, Colorado’s moose population continues to grow.

Recent Moose Conflicts In recent years, moose-human conflicts have arisen as moose move into urban areas. Colorado Parks and Wildlife provides these tips for avoiding conflicts: • Keep a safe distance • Move slowly • Keep dogs on leashes • Back off when moose put ears back, roll their eyes or appear aggressive • Carry a wildlife pepper spray, UDAP or Counter Attack, to use if a moose becomes aggressive COLORADO PARKS & WILDLIFE • 6060 Broadway, Denver, CO 80216 • (303) 297-1192 • cpw.state.co.us � Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.
