1 1 1 I 1 r a 1 y 1 1 June 1987, but returned to the original release location in the 15-mile reach by 9 July where it remained through mid August when contact was lost (presumably tag failure). Another squawfish (D) stayed near the point of release until at least mid June of the following year. On 7 July 1987 it was located 45 miles downstream near the Utah border. By 21 July, it had returned to the original release location in the 15-mile reach. Another squawfish (J) moved upstream in mid July 1986, over the Grand Valley Diversion dam, to the plunge pool of the Price Stub Dam. It remained there until the end of September when it returned downstream. Between early October and the end of March, the fish (J) remained near its initial point of release. In July 1987, it made two brief forays to the base of the Redlands Diversion Dam on the Gunnison River, each time returning to the 15-mile reach after a day or two. In late July 1987, it returned to the plunge pool of the Price Stub Dam and remained there until mid Septem- ber, when it again made its way downstream. From early October through mid May, it stayed within 0.2 miles of its point of release. In mid July 1988, it was again moving upstream for the third year in a row when tag failure occurred. In 1987, four squawfish from the 15-mile reach were equipped with radio transmitters (Fig. 7). One of these (B) remained near the center of the reach through the end of the study, making local movements no more than a few miles from the capture site. Another (G) stayed in the reach during June and most of July, then moved seven miles downstream. It expelled its tag while in a deep pool 2.5 miles below the reach. This fish was again captured in the 15-mile reach at RM 180.5 on 12 May of the following year. Two other tagged fish (H and I) remained in the reach until late July, 17 1
