<br />000606 <br /> <br />--------- APPENDIX C: FY-2002 - 2003 PROJECT DESCRIPTIONS --------- <br /> <br />- Lower portions of levees at the Grand Junction Pipe and Supply gravel pit on the <br />Colorado River and the Unaweep Charolais gravel pit on the Gunnison River to allow <br />entrainment of drifting larvae during spring runoff. <br /> <br />- Lower the Walter Walker SW A levee in three locations to help maintain habitat <br />diversity/complexity <br /> <br />- Seek agreements with federal, state, and local land management areas to enhance and <br />protect habitat. <br /> <br />- Pursue agreements and/or acquisition of easements on Tribal and private lands. <br /> <br />Total out year cost: FY 2003 cost estimated at $1,103,000. <br /> <br />Ill. REDUCE NONNATIVE AND SPORTFISH IMPACTS <br /> <br />87b. NNA/9802: Removal of Nonnative Fishes from Backwater Habitats in the Colorado <br />River in Colorado (CDOW, $17,300) <br /> <br />Completion of a study to remove small nonnative cyprinids and centrarchids from <br />backwaters in the 15- and 18- mile reaches of the Colorado River to benefit native fishes. <br />All backwaters within each study reach were sampled once a week for 3-4 weeks <br />preceding and up to spring runoff in June (this period precedes Colorado pikeminnow <br />spawning). Draft report due to coordinator March 30, 2002. Work may be continued if <br />preliminary results suggest that efforts to date have measurable decreases in nonnative <br />fishes and corresponding increases in native and endangered fishes. Total out year <br />cost: $0 <br /> <br />89, NNA/9802: Colorado River Centrarchid Removal (FWS, $52,000) <br /> <br />Completion of a study to increase survival of age-O Colorado pikeminnow and other <br />native fishes by reducing piscivorous, nonnative centrarchids in riverine backwaters <br />where they are suspected of preying on juvenile, native fishes. All backwaters from the <br />Grand Valley Diversion Dam downstream to the top of Westwater Canyon were <br />electro fished twice prior to runoff and twice following runoff for three years. Draft report <br />due to coordinator May 1,2002. Work may be continued if preliminary results suggest <br />that efforts to date have measurable decreases in nonnative fishes and corresponding <br />increases in native and endangered fishes. Total oUlyear cost: $0. <br /> <br />C-18/19 NNA/9604: Reclamation of Ponds in the Floodplain along the Upper Colorado <br />and Gunnison rivers. (CDOW, $292,000) <br /> <br />The goal of this project is to reduce the potential for predation and competition on <br />endangered fish through chronic escapement of centrarchid sportfish from floodplain <br /> <br />C-8 <br />
