32 <br />• al. (1981 b) reported that normally high flows may be detrimental to larval <br />squawfish. <br />Tyus and Karp (1989) reported a high peak flow with gradual decreasing <br />flow to a stable baseflow to benefit Colorado squawfish reproduction. <br />They also presented discharge and temperature data for the Colorado <br />squawfish migration period and for the actual spawning period for the <br />Yampa River. <br />Haynes et al. (1984) reported modification of seasonal flow regime to be <br />an probable limiting factor to Colorado squawfiish spawning. <br />Archer et al. (1986) presented discharge ranges occurring during <br />Colorado squawfish spawning for the Colorado, Green, and Yampa <br />0 Rivers (Table 2). The wide range of flows and temperatures presented in <br />Table 2 point out the poorly understood relationship between the two <br />variables. <br />o Large discharge fluctuations during winter may impact Colorado squawfish <br />utilizing slow velocity winter habitat. <br />Tyus and Karp (1989) reported winter flow fluctuations to be a potential <br />limiting factor for Colorado squawfish in the Yampa River. Changes in <br />water surface elevation were cited as potentially disrupting normal use of <br />winter habitat. <br />o Flows should decline gradually after runoff to ensure successful Colorado <br />squawfish spawning. <br />0
