Gross Wetted Area Flow Relationship for Strata 6 and 8. <br />5). Adult Colorado Squawfish habitat <br />A. Daytime Habitat (Resting � ctivity <br />The radio telemetry part of the study found Colorado squawfish behavior was <br />highly different between the day and night. In order to understand how squawfish habitat <br />is related to flow, these two periods have to be analyzed according to each activity. <br />Daytime or resting habitat was found to be restricted to pools over at least 1.5 feet deep <br />with half of the observations in pools over 3.8 ft deep. A frequency distribution based on <br />daytime squawfish observations for pool depth was used to indicate the probability of <br />squawfish occupying the pools measured in Strata 6 and 8 clusters (Appendix 7, Table 1). <br />At base flows (less than 300 cfs), the daytime squawfish habitat/flow relationship is <br />primarily a function of pool depth, since average velocity of pool is typically less than 0.5 <br />ft/sec (Appendix 5B & 6B, Tables 7). The WA approach provides more information <br />about habitat quality than the single pool cross section analysis, which is based just on <br />33 <br />
