Title: Colorado squawfish juvenile (250-449 mm) depth utili- <br />zation curves. <br />Parameters: Total water column depth (ft) <br />Period: Year around <br />Location: Colorado, Green and White river reaches designated as <br />concentration or high concentration areas for juvenile <br />Colorado squawfish. <br />Data Utilized: <br />All depth at point of capture data in RARE file for Colorado <br />squawfish 249-449 mm TL, 1979-1983.. <br />Data excluded: <br />Radio telemetry data due to limited sample size. <br />Assumptions: <br />1. Column depth at capture site reflects depth preference <br />of juvenile Colorado squawfish. <br />2. Column depth greater than 2.0 ft is not a limiting <br />factor. <br />Constraints: <br />1. Curve applies only to areas of the upper Colorado River <br />Basin occupied by juvenile Colorado squawfish. <br />Curve coordinates: <br />X (ft) Y (SI) <br />0.5 0.0 <br />0.8 0.1 <br />1.5 0.5 <br />2.0 1.0 <br />5.0 1.0 <br />• -29- <br />
