Show The fishery in Yellowstone River is rated as Class III. This indicates good fishing with some natural reproduction of fish. Under Unit conditions this classification would be maintained. An 8- mile reach of Lake Fork River is also classified as Class III. 73 Under Unit conditions this classification would be reduced to IV or lower. The fish population in these streams includes rainbow, brown, brook, and cutthroat trout. Other species of fish are also likely to be found. As previously mentioned, the drawdown area around the reservoir would detract from the esthetic appeal of the reservoir. The degree of drawdown would fluctuate from year to year. The feeder canal with its fencing and bridges would also be foreign to the area from an esthetic standpoint, as would new roads. Borrow areas outside the reservoir basin, though at present undertermined, would leave scars which if not suitably restored would be esthetically undesirable. A potential source of riprap material would be located immediately downstream from the existing Moon Lake Dam. The acreage to be disturbed has not been determined. It is estimated that due to the Upalco Unit, flows downstream from the Unit would be reduced by an average 10,300 acre- feet each year. Because of the salt concentration effect, salinity of the water at Hoover Dam would increase approximately 1 mg/ 1. This would result in an annual cost to downstream users of $ 41,400 per year. Uintah Unit149 ( 1) Description The Uintah Unit would be constructed when funds are made available by Congress. It would provide partial replacement for Indian- owned water used in the Bonneville Unit. This Unit would develop 53,000 acre- feet of water each year, including 1,000 acre- feet of municipal water for use in the Roosevelt area. A sketch map of the Unit with its two reservoirs, Uinta and Whiterocks, is shown on Figure C- 22. Uinta Reservoir, with a capacity of 47,000 acre- feet would be located on the Uinta River, and entirely within the Uinta and Ouray Indian Reservation. The site is about 8 miles northwest of the town of Neola. At normal water surface elevation the reservoir would inundate approximately 736 acres of land. The valley in which the dam and reservoir would be located is vegetated mostly with pine and quaking aspen. Along the sides of the valley, native grasses are 419 |
