Table ES-1 (Continued) <br />Impact Findings of Environmental Assessment <br />Executive Summryl/ <br />Irrpacts of the <br />Potentially Affected Resource Impacts of the Proposed Action "No Action" Alternative <br />Flaming Gorge: Downstream, whitewater <br />rafters would experience flaws 0-100 cfs <br />below the minimal level of acceptable flows <br />(1,500 cfs) 11 percent of the time between <br />Jones Hole and Rainbow Park in August and <br />Septenber in an average year. However, this <br />would be less of a problem in wetter years. <br />M <br />N <br />8 <br />Flaming Gorge: Same as Proposed Action. <br />Aspinall: Lhder worst-case conditions, Aspinall: Sane as Proposed Action. <br />releases could cause problems in providing <br />recreation-related services in the reservoir, <br />but could make possible some rafting <br />experience in dry years in the Gunnison <br />and Colorado Rivers. <br />Acquisition of water rights on the Yampa <br />and White Rivers could benefit rafters. <br />I. Sportfishing Coldwater: Impacts to sportfishing would <br />depend on impacts to sport fish populations <br />and fisherman access. As noted in the sec- <br />tion on nonnative fishes, impacts to Coldwater <br />trout fisheries could range from beneficial to <br />adverse. Therefore, impacts on sportfishing <br />would range similarly. Modified dam releases <br />rrey also enhance or diminish angler access. <br />Section 7 consultation may preserve some <br />instream flows. <br />Coldwater: Same as the Proposed Action. <br />Wan water: Wanrwater sportfishing oppor- <br />tunities ney be reduced. LTpacts depend <br />on which species are identified as problem <br />species, the degree to which problem sport <br />fish must or can be controlled, and what <br />specific sportfishing rrenagement measures <br />need to be implemented. Impacts are not <br />expected to be significant to inportant <br />sportfishing opportunities. <br />Wamwater: Similar to Proposed Action. Impacts <br />to wanTwater sport fish may occur more slowly. <br />However, there may be increased control of sport- <br />fishing in areas of high incidental take of rare <br />fishes by fishermen. <br />rn <br />X <br />M <br />n <br />c <br />C <br />m <br />cn <br />c <br />3 <br />3 <br />n <br />M W = M = = = M M M M = M M r = M M
