<br />-19- <br /> <br />EFFECTS OF THE PROJECT ON FISH AND WILDLIFE RESOURCES <br />Fish <br />Construction and operation of the Savery-Pot Hook Project could <br />jeopardize the continued existence of the Colorado River squawfish, <br />~ humpback chub, bonytail chub, and the razorback sucker. These fishes <br />are known to occur in the Yampa River and m_Y. occur in the lower Little <br />Snake River itself. <br /> <br />Little is known about the specific water quality requirements for the <br />full life cycle of these fishes or the magnitude of change in existing <br />. chemical, physical, and biological conditions they can tolerate and <br />still survive. Any change in flow regime, salinity, turbidity, <br />temperature, and competition from other species may directly affect <br />. their welfare. Such changes can be expected to occur in the Little <br />Snake and Yampa Rivers if the project is constructed. However, at <br />present, we cannot accurately ascertain their impacts on these fishes. <br /> <br />Construction and operation of the two reservoirs will cause the loss <br />of about 15 miles of free-flowing streams. Seven miles of Savery <br />! Creek in Wyoming will be converted from natural stream habitat to <br />a fluctuating impoundment by construction of Savery Reservoir. Pot <br />Hook Reservoir in Colorado will eliminate 7 miles of natural stream <br /> <br /> <br />
