DRAFT8 <br />Physical habitat variables of interest and catch of Colorado squawfish and NNCs were <br />summarized for each sampling occasion. The data are grouped by yeaz and season in Table 2. <br />Total available habitat was quite variable both seasonally and yearly: Flows at the time of each <br />sam 1' ion were less variable than spring peak flows. The greatest amount of available <br />habitat occurred ' 1994, a lowest in 1995. <br />Habitat availability was not closely correlated to flows at the time of sampling (Pearson's <br />correlation). There were negative correlations between the sampling flows and total area and <br />volume of habitat, but none were significant. However, both summer flows and peak flows had a <br />.~ <br />significant negative correlation with habitat availability in the fall (Table 3). <br />~~ <br />l~"-~~ 4; <br />~~ <br />~~'`) <br />Table 3.
