Strawberry and Duchesne River Sampling Sampling in the Strawberry River suggests a species assemblage dominated by brown trout. Given the assemblage in the Strawberry River and its similarity to the assemblage collected from the outlet evaluations, brown trout are most likely moving upstream into the outlet basin and there is likely very little escapement of brown trout through the outlet, though it probably does occur. Sampling in the Duchesne River in 2004 and 2005 by various agencies revealed a species assemblage dominated by nonnative fishes in both the upper and lower stretches of the river. The only native fish encountered in any of these surveys was flannelmouth sucker. Smallmouth bass were found in sampling efforts beginning around the Myton Diversion (RM 41). Figure 10 shows length frequency information for smallmouth bass sampled during removal efforts from RM 0 to RM 41. This information is courtesy the CRFP. Summary At this point, it is certain that smallmouth bass, walleye, and yellow perch are escaping from Starvation Reservoir and that they are the predominant escapees from the reservoir via the spillway (does not include white sucker which may be increasing in abundance and green sunfish which is apparently established in the spillway basin). Smallmouth bass are currently established in both the Duchesne and Green rivers, though active removal is occurring in the Green River and results from that project suggest that catch rates of certain size classes appear to be declining from 2004 through 2006 data (Upper Colorado River Recovery Implementation Program 2005 annual report, Project No. 123). If the goal of the removal efforts is to eventually reduce the numbers of smallmouth bass to a level where only minimal removal efforts are needed each year, the decision on the appropriate management for Starvation Reservoir then becomes whether or 18
