Utah chub (Gila atraria). Target species captured included 184 smallmouth bass and 48 walleye <br />(Table 4). <br />Evaluation draining of stilling basins <br />Fish removed after the evaluation draining of the outlet basin were again predominantly <br />brown trout and mountain whitefish, though carp, young-of--year (YOY) green sunfish, and <br />rainbow trout were captured in small numbers. Target species included 2 walleye (Table 3). <br />Starvation Reservoir spilled for a period of seven days in 2002, beginning on 2 April. <br />Knowing that the spill in the spring was short and that little chance of escapement existed, it is <br />assumed that none of the fish removed during the evaluation draining escaped from the reservoir <br />during the 2002 spill. Therefore, the evaluation draining served to remove the fish missed during <br />the initial draining due to the spill before the draining was complete. Fish assemblage removed <br />during this effort was similar to the initial draining effort: predominantly carp, green sunfish, and <br />Utah chub. Target species included 158 smallmouth bass and 8 walleye (Table 4). <br />River reach monitoring <br />Within the three-mile section of river directly below the weir, fish sampled before spring <br />irrigation releases were similar to those found in the outlet stilling basin: predominantly brown <br />trout and mountain whitefish, but also carp, cutthroat trout (Oncorhynchus clarki), rainbow trout, <br />and Utah chub (Table 5). Species assemblage was similar in the fall except crews did not see any <br />cutthroat trout, though they did see mountain sucker (Catostomus platyrhynchus) (Table 5). No <br />walleye, smallmouth bass, or green sunfish were observed during spring or fall electrofishing <br />efforts. Given the connection that existed between the outlet basin and the river, it is not <br />surprising that the two samples (river and outlet basin) were so similar. <br />10 <br />
