RECOMMENDATIONS • Do not screen the spillway of Starvation Reservoir. Reservoir screening options are expensive and are not always guaranteed, and with such a low rate of escapement of the target species, other more cost-effective options should be evaluated (see #3 below). • Take no management action in the outlet basin. Given that it was not possible to determine whether fish escaped from the outlet drain or moved in from the river (though the target species most likely came through the outlet), it would be beneficial to determine escapement rates through the outlet before managing it for escapement. • Continue to explore the option of managing Starvation Reservoir to limit the volume of spills. Starvation Reservoir is managed to spill every year and though this will likely continue, lower capacity spills maybe better at containing fish in the reservoir. During the Elkhead Reservoir study, spills less than 200 cfs seemed to be associated with minimal escapement (Miller et al. 2005). • If able to develop a better way to characterize escapement (i.e., determine escapement at different spill volumes), explore the feasibility of chemically treating the stilling basin after a spill to eliminate potential for downstream movement of target species. This could be done by blocking the spillway channel with the block weir again during a spill and then pumping and treating the spillway basin after the spill is completed. This would prevent all adult fish in the spillway basin from moving downriver. • Continue isotope studies to identify sources of nonnative fishes throughout the Green River drainage. This project will help determine where the large number of walleye in the lower Green River is coming from and whether Starvation Reservoir is a bigger source of both walleye and smallmouth bass than initially perceived. 23
