<br />44~j <br /> <br />This allows for a relatively full reservoir during the summer <br />recreation season. Under ultimate Project development, Sugar <br />Loaf Dam will stabilize flows in Lake Fork below the dam <br />throughout the year. Streamflows will average lS ft3fs with <br />a 10 ft3fs minimum flow provided from May through September <br />and 3 ft3fs throughout the remainder of the year. <br /> <br />. <br /> <br />(7) The inundation of an additional 986 acres of land and <br />3.S miles of Lake Fork, and clearing of coniferous forest <br />lands for borrow and roads has resulted in losses of wildlife <br />habitat and feeding areas, with a resultant displacement of <br />wildlife. <br /> <br />(8) Big game distribution data furnished by the Colorado <br />Division of Wildlife indicated that approximately Sl to <br />ISO elk and 201 to 400 deer presently use the area from <br />Turquoise Lake to Clear Creek Reservoir. Big horn sheep <br />are estimated at I to 10 animals; bear are estimated at 21, <br />and mountain lion from 1 to 10 animals. Based on the size <br />of the drainage area and the availability of similar habitat, <br />the effects on the wildlife resources may be minor. Data <br />is not available concerning the magnitude of displacement, <br />effects on migration, and degree of change in species <br />compos it ion. <br /> <br />(9) Development of Turquoise Lake has increased the aquatic <br />habitat and surface acreage available for fish. Fish species <br />stocked include rainbow trout, brown trout, arctic grayling, <br />kokanee salmon and lake trout. <br /> <br />. <br /> <br />(10) Turquoise Lake currently has a thermal range that i~ <br />close to the optimum r~n~e f~r k0kQnee salmon. Enlargement <br />o[ Turquoise Lake has produced at best only a mediocre <br />fishery. Rough fish populations which were present prior <br />to enlargement will continue to be a problem unless brought <br />under control (Colorado Division of Wildlife, letter of <br />March 16, 1972). <br /> <br />(11) Prior to enlargement, Turquoise Lake supported 9,SOO <br />man-days of fishing. Under full Project conditions the <br />lake will provide about 40,000 man-days of fishing annually. <br />The increased fishing pressure will require an additional <br />annual stocking of about 16 tons of hatchery reared fish <br />(Fish and Wildlife Service, 1969). <br /> <br />(12) When Turquoise Lake fills to capacity, waterfowl <br />production and habitat losses will occur along Lake Fork <br /> <br />. <br /> <br />IV-63 <br />
