<br />~1' <br /> <br />SUMMARy OF TASXS <br />This attachment briefly summarizes the tasks listed in the FY-1992 <br />Scope of Work for the Five Year Flaming Gorge Investigations, and <br />is a synopsis of the information presented in Attachment C, This <br />section provides study justifications and summary technical <br />information for the convenience of the reader. Attachment C <br />contains the complete scope of work for each individual task <br />submitted by the lead agency responsible for conducting that task. <br /> <br />Systematic Data Collection and Research <br /> <br />Task 1: Annual assessment of Colorado sauawfish reoroduction and <br />larval abundance in the lower Yamoa River. Colorado. and the lower <br />Green River. Utah. <br /> <br />Description of work: <br />Task 1 is an ongoing SDCR project. UDWR and LFL crews will <br />document timing, and duration of spawning of by Colorado <br />squawfish as measured by capture of drifting larvae. Specific <br />objectives of the study include; detennination of peaks in <br />abundance of drifting larvae and the relative abundance of <br />larvae transported form two spawning locations. <br /> <br />Reproduction will be assessed using drift-net sampling at two <br />sites: one in the Yampa River immediately upstream of the Green- <br />Yampa River confluence (covers Colorado squawfish produced in <br />the Yampa River; site used in past sampling) and another in the <br />Green River below the Desolation-Gray Canyon Colorado squawfish <br />spawning area. Near-shore drift-net sampling (using flow- <br />metered nets) will be conducted daily at dawn during late June- <br />early August. Samples will be preserved in ethanol to allow for <br />subsequent ageing using otoliths so that spawning times can be <br />determined. <br /> <br />This study is critical in terms of documenting annual <br />reproduction of Colorado squawfish and other species so that <br />various hypothesis regarding the effects of modified flows from <br />Flaming Gorge dam can be evaluated. <br /> <br />Deliverables: <br />UDWR will provide sorted and preserved drift net samples from <br />lower Green River collections to LFL. LFL will sort and <br />preserve drift net samples from the Yampa River collections. <br />All samples will be identified. verified, and curated by LFL <br />personnel. A summary report will be submitted at the end of the <br />fiscal year. <br /> <br />Budget I: <br />-Labor <br /> <br />UDWR <br />$23,800 <br /> <br />LFL <br />$23,800 <br /> <br />'Does not include FWS overhead <br /> <br />Budget does not include FWS ove~ad <br />
