The flows on these days were 383 and 358 cfs, respectively. Six transects were <br />surveyed along this habitat cluster. One transect was placed across the fast rapid at the bottom <br />(control), two across the shallow and deep runs in the middle, and two transects across the fast <br />riffle at the top of the cluster. Habitat type and substrate and width, depth and water velocity <br />measurements were taken along each transect. The length of the cluster was 821.2 ft, mean width <br />154.0 ft (54.5~257.1 ft.) and mean depths ranged from 1.0-3.94 ft. The primary habitat types found <br />in the cluster at 383 cfs were shallow runs (51 %) and deep runs (27%), followed by fast riffles <br />(12%) and slow shallow pools (10%). There were no Class I or Class II pools. The primary habitat <br />available to Colorado squawfish at all simulated flows (1-500 cfs) were deep run habitats. <br /> <br />Strata 3 <br /> <br />Cluster] (rm 45.5) <br /> <br />This cluster was sampled 22 October 1996 (Appendix 2, Table 2) near Disappointment Draw <br />on the Yampa River. The flovv on this day was 433 cfs. Six transects were surveyed along this <br />habitat cluster. One transect was placed across the fast riffle at the bottom (control), two across the <br /> <br />21 <br />
