Ft. Collins. The results of this work appeared in a Master's Thesis entitled "Evaluation of Colorado Squawfish Stocking In Kenney Reservoir, Rangely, Colorado (Trammell 1991), and which were published later (Trammell et al. 1993). The objectives of Trammell's study were to evaluate the ecology and behavior of the stocked fish in the reservoir and river, and determine if they could provide a viable reservoir sportfishery. Table 1. Stocking dates, numbers, lengths, and external identifying marks of Colorado Squawfish stocked into Kenney Reservoir from 1988 to 1990.

Trammell et al. (1993) found that Colorado Squawfish stocked in Kenney Reservoir remained there for only a short time (two days to one year). She found large numbers of fish below the reservoir, and reasoned they left over the spillway, usually in association with high discharges occurring shortly after stocking. Once in the White River below the reservoir, she reported they moved downstream and out of the study area (into Utah) en mass. Very few of the fish moved upstream of the reservoir. The report concluded that stocking Colorado Squawfish does not appear to be an effective mitigation measure for impacts from an impoundment nor does it appear that stocking Colorado Squawfish will produce a reservoir sportfishery. The present report summarizes studies by the CDOW that began in 1991 and continued through 1992. It was an interim period between the conclusion of Trammell's work and the start of a study of Colorado squawfish in the White River by Irving and Modde (1994}. The present report completes the evaluation of the Colorado', 3
