<br />The USFWS has sUbsequently theor'zed that too much water 'n <br />nursery areas may have been a contr'but'ng problem. Any <br />solut'on would probably have to address both factors. <br />Add'tional results from ongo'ng research should be in by late <br />sUlMler. <br /> <br />2. - Water impacts - Us'ng warmer 'water out of Flaming Gorge <br />'ncreases wear on the turb'nes. Temperature regulation also <br />requ'res var'able level 'ntake structures which can lead to <br />reduced turbine efficiency due to vary'ng head and, 'n some <br />cases, may requ're bypass'ng the turb'nes altogether. <br /> <br />The Bureau has Hm'tat'ons on how H can operate Flaming Gorge, <br />the operation of wh'ch 'S governed by and must be 'n accordance <br />wHh the Colorado R'ver Storage Project Act. The present <br />management pr'or't'es of the Bureau at Flam'ng Gorge are as <br />follows: <br /> <br />a. regulate streamflow <br />b. water conservat'on <br />c. power generat'on <br />d. endangered species <br />e. game f'sh <br /> <br />Any change 'n flow for nsh needs could signH'cantly reduce <br />power del'very and affect revenue d'str'but'on. Long-term lower <br />bas'n del'very requ'rements could also be 'n confl'ct. Flood <br />control operat'ons are the pr'mary responsibnHyof the U.S. <br />Army Corps of Eng'neers and under 33 C.F.R. 208.11, published <br />October 13, 1978, flood control's not a pr'mary obl'gation at <br />Fl am' ng Gorge. <br /> <br />Reregulation below Flam'ng Gorge (e.g. ,w'tha newly constructed <br />facil'ty) could reduce the impacts of temperature regulation on <br />power generation and could be used to smooth out flows from <br />da'ly power fluctuat'ons from Flam'ng Gorge. <br /> <br />3. Where - Temperature and flow changes could be man'pulated at <br />Flaming Gorge dur'ng per'ods of growth, m'gratory, spawning and <br />larvae transport 'n the months of May-October if the above <br />descr'bed 'mpacts were found to be acceptable or mH'gated. <br /> <br />As d'scussed, a reregulat'on dam could be used downstream to <br />warm water and regulate flows. The capacity of such a fac'lity <br />to create needed temperature changes and to further regulate <br />flow would have to be sufficient to justify the cost. Siting of <br />a fac'lity may prove unfeas'ble because of the proxim'ty to <br />Dinosaur Nat'onjl Monument. <br /> <br />4. ~ - Bureau of Reclamation <br /> <br />" <br /> <br />- [, - <br />
