return water then continues downstream about three miles where it <br />enters the Colorado River at RM 166.4. The power plant is an <br />impediment to fish moving further upstream. The tailrace discharge <br />sometimes equals or even exceeds the discharge of the Lower Gunnison <br />River downstream of the Redlands Dam during the post-runoff summer <br />months. Several questions arise: 1) could the tailrace discharge from <br />the Redlands canal compete with the discharge of the Gunnison River <br />downstream of Redlands Diversion Dam, 2) could this confuse Colorado <br />pikeminnow.as they move upstream past the confluence of this tailrace <br />water with the Colorado River, and 3) are Colorado pikeminnow moving <br />up this tailrace? If they are, 1) how far upstream do they move, and <br />2) how long do they reside there? If so, could this affect the number <br />of pikeminnow that move up the Lower Gunnison River and eventually <br />move through the Redlands passageway? <br />4. Pursue fish passage at other instream barriers. This was one of the <br />end products identified for this evaluation. A fish passageway was <br />constructed at the Grand Valley Irrigation Company's diversion dam on <br />the Upper Colorado River near Palisade during the winter of 1998 (RM <br />185.3; Kubitschek and Mefford 1997; Burdick 1999). Construction of <br />other fish passage facilities are planned at Price-Stubb Dam (RM <br />188.3) and Government Highline Diversion Dam (RM 193.7) on the Upper <br />Colorado River between 2002 and 2005 and Hartland Diversion Dam on the <br />Gunnison River. Selective passage should be considered where needed. <br />5. No modifications to the existing within-passageway features or to the <br />overall mechanical operation of the passageway at Redlands are <br />recommended. <br />51
