<br />of the Lower Gunnison River constantly monitored and logged any <br />movement of radiotagged fish in the vicinity. Following radiotag <br />implantation in 1997. only two radiotagged fish were detected about <br />O.l-mile downstream of the Redlands Diversion Dam plunge pool <br />intermittently during mid-July and mid-September. Two other <br />radiotagged fish were detected occupying a lower section of the 2.3- <br />mile reach of the Lower Gunnison River intermittently during mid-July <br />and mid-September. Unfortunately. the radiotag and carcass of one <br />Colorado squawfish implanted in June 1997 was found in Walter Walker <br />State Wildlife Area in August. <br /> <br />IV.

Eighteen sub-adult and adult Colorado squawfish were <br />collected in the fish trap of the fish passageway at the <br />Redlands Diversion Dam. Four fish were collected in July and <br />the remaining 14 in August (Appendix; Figure 1). On two <br />separate occasions. multiple captures of squawfish were <br />recorded during the same day. On 3 August. six fish were <br />collected and on 4 August, four were collected (Table 1). <br /> <br />2 <br />
