EXECUTIVE SUMMARY Between 1988 and 1990, 96,600 Colorado squawfish (Ptychocheilus lucius) were stocked in Kenney Reservoir, a mainstem impoundment on the White River near Rangely, Colorado. The Colorado squawfish is a state and federally listed endangered species and Kenney Reservoir was constructed in habitat occupied by these fish. As part of the mitigation for the reservoir project, Colorado squawfish were stocked to artificially establish a population above the dam and create a sportfishery in the reservoir. The first monitoring phase of this stocking was from 1989 to 1990 as a graduate student research project. This study determined that large numbers of stocked squawfish quickly left the reservoir and moved downstream of the study area. The author concluded the disappearance of Colorado squawfish from the reservoir was due to downstream movement, natural mortality and predation, and possibly to the difficulty of sampling these fish at a juvenile size in a large water body. The present study continued the monitoring effort during 1991 and 1992. The primary objective was to determine if stocked Colorado squawfish still occurred in the reservoir and in the river above and below it. Sampling of the reservoir was conducted by electrofishing, trammel and gill netting, and seining. The river was sampled mainly by seining although electrofishing and trammel nets were used at one large backwater. This study completes the evaluation of stocking above the dam. Four Colorado squawfish were captured in 1991 -- one in the reservoir and three in the river above the reservoir. None were collected in 1992. No stocked squawfish were found either year in the river downstream of the reservoir where most of the recaptures had occurred in the previous study. All four fish were Age 2+ which was also the age of the oldest fish found in the previous study. Older and larger fish were not captured. The result from this stocking effort is that the Colorado squawfish stocked in Kenney Reservoir no longer occur in the reservoir or in the White River above the reservoir. In conclusion, the attempt to artifically create a Colorado squawfish population above the dam and a sportfishery in the reservoir was unsuccessful. However, two suspected stocked Colorado squawfish were collected recently (1993 and 1995) downstream of the dam, indicating that some stocked fish may have survived. The contribution of these stocked fish to wild Colorado squawfish populations and their role in the recovery of the species has yet to be determined. Monitoring for these stocked fish should continue below Kenney Reservoir. v
