                    Description:Colorado Parks and Wildlife’s (CPW) statutory mission 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 strategic stewards of Colorado’s natural resources (C.R.S. § 33-9-101 (12) (b)). As CPW is responsible for the management and conservation of aquatic resources within the State, we are asked to review projects that may affect aquatic habitats or populations. Specifically, CPW staff is often engaged by the Army Corps of Engineers (USACE) to review permit applications related to the design, construction, and monitoring of whitewater parks (WWPs) regulated under Section 404 of the Clean Water Act. WWP projects typically fall under the following permits: 
NWP 27 - Aquatic Habitat Restoration, Establishment, and Enhancement Activities
IP - An individual, or standard permit, is issued when projects have more than minimal individual or cumulative impacts, are evaluated using additional environmental criteria, and involve a more comprehensive public interest review.

Research Objectives
To determine the impact of whitewater parks on fish passage, habitat, natural river processes and potential conflicts between anglers and boaters. ​
Project Description
With more whitewater parks than any other state, Colorado has become the epicenter for whitewater park design and construction. Whitewater parks contribute to local communities by providing revenue from tourism, promoting public interest in rivers and creating exciting new recreational opportunities. However, no comprehensive studies have been completed to assess the effects of whitewater parks on fisheries and river ecology.
To better understand the effects of whitewater parks, CPW initiated a comprehensive research project in cooperation with Colorado State University to study a whitewater park in Lyons, Colorado. Using Passive Integrated Transponder (PIT) telemetry systems, researchers tracked fish movement to directly assess the effects of the Lyons Whitewater Park on upstream fish migration. PIT telemetry is a type of passive radio frequency identification that detects uniquely coded radio tags with fixed antennae. In addition to the PIT tag study, hydraulic modeling was used to analyze flow velocity, direction and depth. These data were used to compare fish passage and habitat in the whitewater park and a natural river channel. Results from the Lyons study indicate that whitewater parks can impair upstream migration of fish and create unfavorable habitat conditions for fish.
Information from this study is being used to develop design guidelines for whitewater parks that optimize both recreational and ecological benefits. As a variety of whitewater park designs are being used throughout Colorado, CPW will continue to research different types of structures and their effects on fish, benthic macroinvertebrates and habitat. Future studies are planned for the proposed w​hitewater parks on the Uncompahgre River in Montrose, Colo., and the Gore Canyon Whitewater Park at Pumphouse on the Colorado River. ​

                    Description:With over 30 whitewater parks (WWPs) either completed or in the
planning phases, Colorado is the epicenter for WWP development in the
United States. 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. [show more]

                    Description:Plague seroprevalence was estimated in populations of pumas and bobcats in the western United States. High levels of exposure in plague-endemic regions indicate the need to consider the ecology and pathobiology of plague in nondomestic felid hosts to better understand the role of these species in disease persistence and transmission.
