It is estimated that at the outset approximately one <br />million visitor days could be anticipated at the 'reservoir area, with a <br />rapid increase thereafter. <br /> <br />proiect Statistics <br /> <br />Estimated Costs: <br /> <br />Flood control <br />Irrigation <br />Recreation <br />Fish and wildlife <br />Road relocation <br /> <br />$ 34,734,000 <br />32,432,000 <br />24,159,000 <br />9,375,000 <br />201,000 <br /> <br />Total Cost <br /> <br />$100,901,000 <br /> <br />Narrows Reservoir capacity (acre-feet): <br /> <br />Dead and inactive <br />Irrigation <br />Joint use (irrigation, flood control <br />and sediment) <br />Flood control <br />S!-1rcharge <br /> <br />50,160 <br />373,025 <br /> <br />75,000 <br />475,000 <br />575,373 <br /> <br />1,548,558 a.f. <br /> <br />119,400 a.f. <br /> <br />1.29 to 1 <br /> <br />Total Capacity <br />Estimated annual irrigation yield <br />Benefit-cost ratio <br /> <br />Environmental Impact <br /> <br />The principal environmental impact of the Narrows project will be <br />the inundation of several miles of stream channel by the reservoir. No <br />significant stream fishery now exists in that portion of the river. <br />However, a considerable reservoir fishery will be created by the water <br />impounded in the reservoir. Virtually all of the lands to be acquired <br />for the reservoir are now in private ownership. <br /> <br />Some loss of nesting sites for waterfowl and upland game birds will <br />occur. However, waterfowl use of the area is expected to almost triple <br />as a result of the increased water area which will be available as the <br />result of the reservoir impoundment. The hunting area for small upland <br />game, such as pheasants and rabbits, will be decreased, but will be <br />increased for waterfowl. Sport hunting for other animals such as <br />racoons, coyotes and foxes will be decreased as the result of the reser- <br />voir inundation of the lands. There will be no impact on big game <br />animals. <br /> <br />No adverse downstream water quality effects are anticipated. The <br />operation of the dam and reservoir will reduce the seasonal and cyclical <br />fluctuations in the water supply and permit better water quality to be <br />applied to irrigation lands. Construction of the Narrows Dam and Res~ <br />ervoir and development of the Jackson Lake Reservoir will create a high <br /> <br />-2- <br />
