<br />SUMMARY OF FINDINGS <br /> <br />1. No Colorado squawfIsh or other endangered species were captured during this study. <br /> <br />2. A total of 20 species of fish including six native and 12 non-native species were handled during <br />the study. Six hybrid combinations of native and non-native sucker species were also handled. <br /> <br />3. A total of 1,344 fIsh representing 11 species and fIve hybrids were tagged during the study. <br /> <br />4. A total of 265 fish, representing seven species were recaptured during the investigation resulting <br />in an overall recapture rate of approximately 19.7%. <br /> <br />5. Twenty-eight fish representing six species were documented moving over the diversion structure <br />during the study; 21 passing in an upstream direction and seven passing in a downstream <br />direction. Three of the 28 fISh were northern pike tracked using radiotelemetry and the <br />remaining 25 were marked with Flay or PIT tags and subsequently and recaptured. <br /> <br />6. A total of eight fish representing surrogate species (flannelmouth sucker and northern pike) <br />were documented moving over the diversion structure during the study; four passing in an <br />upstream direction and four passing in a downstream direction. <br /> <br />7. Fish passage was documented during high flows (> 224 cfs) and low flows (< 224 cfs). <br /> <br />8. Three radiotagged northern pike passed upstream over the diversion structure at flows ranging <br />from 268 to 1680 cfs. <br /> <br />9. No evidence of fISh aggregations was found below the diversion structure during the study, <br />indicating that the structure did not impede upstream movement. <br /> <br />10. Physical habitat parameters including depth and velocity measured in the diversion structure <br />during low flows were within the range of utilization documented for Colorado squawfish. <br /> <br />ii <br />
