<br />shallow and deep runs in the middle, and two transects across the fast riffle at the top of the cluster. <br />The length of the cluster was 1,212.7 ft, mean width 162.2 ft (106.0-280.7 ft.) and mean depths <br />ranged from 0.97-1.95 ft, The primary habitat types found in the cluster at 433 cfs were shallow <br />runs (68%) and fast riffles (27%), followed by shallow pools (5%). There were no Class lor Class <br />II pools, The primary habitat available to Colorado squawfish at all simulated flows (1-500 cfs) <br />were shallow run habitats. <br /> <br />Cluster 3 (rm 51.0) <br /> <br />This cluster was sampled on 22 and 23 August 1996 (Appendix 2, Table 3) near the Little <br />Snake River confluence, Yampa River. The flows on these days were 184 and 176 cfs, respectively. <br />F our transects were surveyed along this habitat cluster. One transect was placed across a shallow <br />run at the bottom (control), two across shallow runs in the middle, and two transects across shallow <br />runs ar the top of the cluster. The length of the cluster was 1,142.5 ft, mean width 418.2 ft (181.5- <br />652.0 ft.) and mean depths ranged from 0.54-0,94 ft. The primary habitat type found in the cluster <br />at 184 cfs was shallow runs (85%), followed by shallow pools (15%). There were no Class [ or <br />Class II pools. The primary habitat available to Colorado squawfish at all simulated flows (1-500 <br />efs) were shallow run habitats. <br /> <br />Strata 4 <br /> <br />Cluster I (I'm 53.5) <br /> <br />Ihis cluster was sampled on 16 and 17 October 1996 (Appendix 2, Table 4) near the bottom of <br />Cross Mountain, Yampa River. The flows on these days were 217 and 215 cfs, respectivcly. Six <br />transccts were surveyed along this habitat cluster. One transect was placed across the fast riffle at <br />the bottom (control), two across the shallow and deep runs in the middle, and two transects across <br />the fast rime at the top ofthc cluster. The length of the cluster was 1,205.5 ft, mean width 254.1 ft <br />(197.4-260.0 ft.) and mean depths ranged from 0.61-1.97 ft. The primary habitat type found in the <br />cluster at 215 cfs was shallow runs (76%), followed by shallow pools (14%), deep runs (9%) and <br />fast riffles (I %). There were no Class I or Class II pools. The primary habitat available to Colorado <br />squawtish at all simulated flows (1-500 efs) were shallow run habitats. <br /> <br />Cluster 2 (1'111 54.0) <br /> <br />This cluster was sampled on 17 and 18 Oetober 1996 (Appendix 2, Table 5) near the bottom of <br />eros:; Mountain, Yampa River. The flows on these days were 215 and 238 cfs, respectively. Six <br />transects were surveyed along this habitat cluster. One transect was placed across the fast riffle at <br />the botlol11 (C<1ntrol), two across the shallow and deep runs in the middle, and two transects across <br />the fasl rime at the top of the cluster. The length <lithe cluster was 1,422.9 ft. mean width 200.9 ft <br />(179.6,240.7 ft.) and mean depths ranged from 0.86-1.25 ft. The primary habitat type found in the <br />cluster at 238 cis was shallow runs (96%), followed by :;hallow pools (4%). There were no Class I <br /> <br />22 <br />
