respectively. The only major change was the presence of <br />rainbow trout (Sa1mo gairdneri) in 1985. First <br />stocked in Kenney Reservoir in 1984, rainbows moved <br />upstream out of the reservoir and over the dam where they <br />were collected only to Rangely, 16 km (10 mi.) downstream. <br />A total of 41 Colorado sauawfish was captured in the <br />study area by all sampling efforts combined in 1983 lll). <br />1984 {12). and 1985 (18). An additional 21 specimens were <br />momentarily stunned while electrofishin~ but could not be <br />captured. Of the 62 Colorado sauawfish accounted for by <br />capture or si~htin~. only 13~ (8) occurred above the dam <br />axis while 87~ (54) occurred between the dam site and the <br />CO/UT stateline. Forty three {69~) of the 62 occurrences <br />were within-the 16 km (10 mi.) below the dam axis (between <br />Taylor Draw Dam and Rangely) suggesting a preferred area <br />for Colorado squawfish. <br />Of the 41 Colorado squawfish captured 15 were <br />implanted with radio transmitters. Because all the <br />squawfish implanted during this study exceeded 500 mm TL <br />(51?-744 mm TL), the movements observed were probably <br />representative of adult Colorado squawfish in the White <br />River. Based on length frequency, the majority of <br />Colorado squawfish captured and sighted during this study <br />were adults. squawfish in the White River showed upstream <br />and downstream movement, including passage through the-dam <br />axis before the dam was closed. Seven specimens entered <br />the Green River of which two apparently participated in <br />xvi <br />
