<br />000602 <br /> <br />---------- APPENDIX C: FY-2002 - 2003 PROJECT DESCRIPTIONS ---------- <br /> <br />85d. Green and Colorado River Sediment monitoring (FWS, USGS, $38,000) - This study will <br />develop methodology to quantify site sediment dynamics and relate that information to a <br />physical and biological process which create habitat for endangered fish. Recommended <br />peak flows in the Flaming Gorge synthesis report are intended to maintain active, <br />complex channel characteristics and spawning bars, and to create conditions which clean <br />fine-grained sediments from cobble substrates at spawning bars. This work will <br />continously monitor sedimentation and erosion at complex habitat sites in response to <br />flow enhancement and natural cycles. Total out year cost: $38,000. <br /> <br />86. HMG/9801: Peer Review of Geomorphological Studies (FWS, up to $10,000) <br /> <br />Geomorphology has become an important aspect of flow recommendations, with high <br />flows often recommended based on the need to maintain a channel morphology that <br />provides backwater and main channel habitats for endangered fishes. Also, channel <br />monitoring is becoming increasingly important as the Recovery Program moves from <br />instream flow identification to flow protection. To ensure that these projects are designed <br />properly, a peer review panel has been established to: I) review and commenl on all new <br />scopes of work containing a geomorphological component; and 2) review draft reports <br />containing a geomorphological component as part of the Program's approved peer review <br />process. Total out year cost: determined on an annual basis. <br /> <br />104. HMG/0002: Fluctuating Flow Effects on Young Overwintering Colorado Pikeminnow <br />(FWS, $107,600) <br /> <br />This study evaluates the effects of winter operations of Flaming Gorge Dam on the <br />survival, distribution, and nursery habitats of age-O Colorado pikeminnow. The study <br />will: I) annually estimate overwinter survival in a 40-mile study reach; 2) delermine <br />specific habitat changes and accompanying fish movement resulting from flow <br />fluctuations; and 3) develop a bioenergetics model that assists in interpreting the field <br />data and predicts the effects of conditions other than those observed during the study. <br />Total out year cost: $0 <br /> <br />107. HMG/0203: Gunnison River/Aspinall Temperature Modeling: Phase 1I (Hydrosphere, <br />BaR, $95,300 FY02-03) (Placeholder, awaiting Management Committee approval.) <br /> <br />Colorado pikeminnow historically were found in the Gunnison River as far upstream as <br />the city of Delta; however, cool stream temperatures have been identified as a significant <br />impediment to re-establishment of pike minnow habitat in this reach of the Gunnison <br />River. Phase I of this study indicated that the Aspinall reservoirs have significantly <br />altered river temperatures, and that warmer river temperatures near Delta could be <br />achieved through a temperature control device at Blue Mesa Dam. Phase II will develop <br />Aspinall reservoirs temperature models and a stream temperature model of the Gunnison <br />River below Crystal Reservoir to gain a more complele quantitative understanding of the <br />impacts that a temperature control device at Blue Mesa could have on stream and <br />reservoir temperatures. Total out year cost: $0 <br /> <br />C-4 <br />
