ANS Fact Sheet

AQUATIC NUISANCE SPECIES (ANS) Program OVERVIEW

Background

The State Aquatic Nuisance Species (ANS) Act was signed into law
May 2008. 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.

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.

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.

�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.
