<br />) <br /> <br />2. Determine the extent of movement of juvenile and adult Colorado <br />squawfish in the fish passageway, in the Redlands Diversion Dam <br />plunge pool, and in the 2.3-mile reach downstream of the <br />diversion dam using radiotelemetry technology. <br /> <br />3. Determine the utility of using fish passage as a recovery tool <br />for these species at other instream barriers. <br /> <br />4. Determine the "threshold" or minimum flow when Colorado squawfish <br />vacate the plunge pool and 2.3-mile reach using radiotelemetry <br />and direct observation. <br /> <br />Evaluate movements and distribution of Colorado squawfish that pass <br />through the Redlandsfish passageway. <br /> <br />Obiectives <br /> <br />1. Determine movement patterns and distribution of sub-adult and <br />adult Colorado squawfish that pass through the Redlands Fish <br />Passageway that are released immediately upstream .of the Redlands <br />Diversion Dam. <br /> <br />) <br />, <br /> <br />2. Identify any Colorado squawfish congregations that may be related <br />to the spawning period in the Gunnison River. <br /> <br />3. Determine if any of the Colorado squawfish that have passed <br />through the Redlands fish passageway are associated with other <br />Colorado squawfish at spawning site(s) in the Gunnison River. <br /> <br />End Products <br /> <br />1. Definitive data on passage--number of species; numbers per <br />species; seasonal use and distribution by species. <br /> <br />2. Data on temporal and spatial movement and distribution of <br />radiotagged Colorado squawfish relative to the fish passageway-- <br />within and near the fish passageway, in the plunge pool, and in <br />the 2.3-mile reach. <br /> <br />3. Recommendations as to whether to pursue fish passage at other <br />instream barriers or if modifications are needed at Redlands. <br /> <br />Redlands 7 <br />
