Table AI. Continued. Studies Project 98b (continued) Starvation escapement (Project 119) Middle Green River smallmouth bass control (project 123) Duchesne River nonnative fish removal, fish composition monitoring, and riffle habitat measurements (Project 124) Study Goal and Objectives 2) Determine population size and structure of northern pike in the study reach and the subsequent changes in the population size and structure after translocation. 3) Monitor movement of northern pike into and out of the study area and within the study area. Movements will be monitored within years, between years, and seasonally. 4) Maintain public support for the Recovery Program by providing off-channel angling opportunity to Yampa Valley anglers with northern pike removed from the Yampa River. 5) Monitor the native fish community in the study area. 6) Monitor smallmouth bass in the study area. Goal Obtain an estimate ofthe rate of escapement of walleye and smallmouth bass from the spillway and outlet works of Starvation Reservoir. Obiectives 1. Review and synthesize available data and reports on smallmouth bass populations and other fish species of the Duchesne River adjacent to Starvation Reservoir. 2. Complete an initial draining of the outlet works stilling basin prior to the irrigation season (March) Completed in 2002 and 2004. 3. Complete an evaluation draining of the spillway stilling basin following spill (July). 4. Complete three sampling passes through the three-mile river reach below Starvation Reservoir (Pre-spill, during spill and post-spill; May - July). Completed in 2002 5. Complete an evaluation draining of the outlet works stilling basin following the irrigation season (October). The outlet works stilling basin was drained in 2002 and 2004. 6. Obtain an estimate of the rate of escapement of target species through the spillway and outlet works of Starvation Reservoir (Jan). Goal Control smallmouth bass populations in the Green River. Obiectives 1. Calculate an annual population estimate of smallmouth bass in the Green River. 2. Remove smallmouth bass in the Green River from Echo Park (RM 344) to Swasey's Rapid (RM 132). 3. Determine efficiency of smallmouth bass removal efforts. Goal Improve survival of endange~ed fish in the Lower Duchesne and Green Rivers, monitor the fish community in the Lower Duchesne River, and measure riffle habitat changes since implementation of base flows.
