locations where Colorado squawfish were previously captured, twice-monthly systematic sampling of the larval fish community, and a fall young-of-the-year survey, similar to that conducted as part of the Interagency Standardized Monitoring Program. The Redlands Diversion prevents access by Colorado squawfish and razorback sucker to 55 miles of apparently useable habitat. Proposals exist to provide access to the Gunnison River by either removing the diversion structure or building a fish-passage facility to move fish over the structure. Although Colorado squawfish congregate below the structure at certain times 8q (Osmundson and Kaeding 199, it is unknown whether the fish would have moved further into the Gunnison River, and if so, how far they would have gone. To examine the potential use of the Gunnison River by Colorado squawfish, a maximum of four fi per year (if available) should be collected from the Redlands Diversion pool, implanted with radio transmitters, and moved upstream over the dam. In addition, any Colorado squawfish collected in the Gunnison River during other studies (up to a maximum of four per year) should also be implanted with radio transmitters and monitored in conjunction with the Colorado River fish. The radiotelemetry study should be conducted for tie years and should use long-term transmitters if possible. Additional fish should be implanted every year. The fish should be monitored weekly from April through October; bimonthly or monthly for the remainder of the year. This study could be conducted in conjunction with the Gunnison River habitat study to document habitat use by the radio-tagged Colorado squawfish. Current efforts to explore removal of the Redlands Diversion Dam should continue. 37
