2003 <br />Fieldwork for 2003 was postponed due to Starvation Reservoir not spilling. <br />2004 <br />Initial draining of stilling basins <br />Fish collected after draining the outlet basin were predominantly brown trout. Additional <br />species included largemouth bass (Micropterus salmoides), mountain sucker, mountain <br />whitefish, and numerous mottled sculpin (Cottus bairdii). Target species included two walleye <br />and two yellow perch (Table 3). <br />Fish removed after draining the spillway basin were predominantly centrarchids, though a <br />few cyprinids and salmonids were caught during this effort. Target species included 96 <br />smallmouth bass and one walleye (Table 4). Note in Table 4 that though the 2002 drainings were <br />considered successful at removing fish, a few fish remained in the spillway basin (one brown <br />trout, 10 carp, two Utah chub, one walleye, and many smaller green sunfish and smallmouth <br />bass). These fish are believed to have eluded the removal effort from the 2002 drainings as even <br />though the draining was successful, it was not possible to completely drain the basin (the pumps <br />used for this project become much less effective when the depth of water is less then four <br />inches). Instead, the spillway basin was drained down to the concrete flooring of the basin as far <br />as possible and then seined to remove as many fish as possible. <br />Evaluation draining of stilling basins <br />Fish removed after draining of the outlet basin were again predominantly brown trout and <br />mountain whitefish. Crews also captured white sucker (Catostomus commersonii), mountain <br />sucker, and carp. Target species included one walleye and 48 yellow perch (Table 3). <br />11 <br />
