<br />/::-:>,\ <br />~ l <br /> <br />are being located and inventoried in 1991, an environmental assessment and <br />permits for development work are also being written. <br /> <br />Work at the demonstration project area of Old Charley Wash will include <br />development of an engineering design for removal/improvement of existing water <br />control structures, for construction of dik.es, and siting a water pump. This <br />will provide for uncontrolled and controlled water levels in the Wash that will <br />be used for fish studies. Additional areas will also be evaluated for similar <br />work type of developments if needed in the future. <br /> <br />VI. Task Description (FY 1992): <br /> <br />l. Review 1991 data collected on water levels (calibrated stage records, <br />elevation surveys) ,probe studies, etc., at flooded bottoms in the Ouray <br />Area, and incorporate into the 1992 study designs. Calculate flow <br />requests for 1992, and submit through FWS channels to BOR before April, <br />1992. <br /> <br />2. survey the Green River for additional flooded lands that would be <br />important for rare fishes. Areas identified wold be sampled for fish use, <br />including rare fishes and potential competitor species. <br /> <br />3. Review fish use data, evaluate the habitat utilization of rare fishes <br />for different habitats, determine important features flooded lands for <br />fish recovery efforts. <br /> <br />4. Determine patterns of fish movements into and out of flooded lands, <br />including Old Charley Wash, determine the significance of these movements <br />relative to the rare fishes. <br /> <br />5. Develop means for control of fish access into naturally flooded lands, <br />decide which fishes should be controlled, what sizes might be removed or <br />restricted from areas, evaluate methods for monitoring rare fish usage. <br /> <br />6. Conduct stocking experiments with razorback suckers to determine <br />proper management procedures, and to enable further restoration planning. <br />Results include foods eaten, growth in different habitats, effects of <br />predation, etc. Coordinate efforts with Subproject B. <br /> <br />VII.
