more than 10 days in late June. Subsequent radio contact with it occurred <br />in a side channel of the Colorado River 2.5 miles below the confluence. <br />Because the location did not change for the next three weeks, we searched <br />the bottom and found the transmitter lying free in three feet of water. <br />This fish may have moved to the site and expelled its transmitter, moved to <br />the site and died, or perhaps died somewhere upstream and floated to this <br />site where it decomposed. In any case, the last reliable contact with this <br />fish was made at the mid-channel location in the Gunnison River (in late <br />June). Another Colorado squawfish moved out of the 15-mile reach two weeks <br />after release and spent at least two weeks at various sites in the lower 18- <br />mile reach. In mid-July it was located in a side-channel at the site of the <br />old Walker Wildlife Area (WWA) backwater; it has not moved from that <br />location in the past six months. This fish may have died or has perhaps <br />expelled its transmitter. One squawfish has stayed within the 15-mile reach <br />for the entire study period, moving between various sites within 1.5 miles <br />of the point of capture. Another squawfish stayed within 1.6 miles of the <br />capture site for five weeks following its release, then moved upstream out <br />of the 15-mile reach to the base of the Price Stub Dam (RM 188.2) near the <br />end of July. It remained in that vicinity through mid-September, then <br />returned to the capture area and has remained there during the past four <br />months. <br />Contact has been maintained with one female razorback sucker (Fig. 2). It <br />left the point of capture one week after release and moved out of the 15- <br />mile reach. It was next located 10.8 miles downstream in a backwater of the <br />WWA side channel. Although it has moved in the local area, it has not left <br />the side channel during the past six months. <br />9
