<br /> <br /> <br /> <br />1 <br /> <br /> <br /> <br /> <br /> <br />Colorado Squawfish #40:7419 (CS741) <br />CS741was captured by angling at RM 82.7 on 27 August 1996. This fish was relocated <br />on at least 12 separate occasions and was never found more than one river mile from the <br />capture location (Figures 4 and 5). CS741 was almost always located in one of the two <br />large pool habitats located within this area. The only exceptions occurred when it was <br />found in an eddy along the lower edge of one of the large pools, or was found in a run at <br />the head of the other pool. The two large pools were unique because each had a <br />submerged shelf in deep slow moving water. The lower pool had a bedrock shelf and the <br />upper pool contained a submerged sandbar. CS741 was usually associated with one of <br />these two habitats. Although more than 0.3 miles of run and riffle habitat existed <br />between the two pools, CS741 never remained within this area during monitoring <br />periods. <br />A 24 hour observation was conducted on CS741 beginning at 9:15 a.m. on 23 October <br />1996 (Figure 6). CS741 remained mostly inactive, however did change positions once <br />during the daylight hours. CS741 became moderately active after sunset then changed <br />habitats prior to 10:15 p.m. when it was relocated in an eddy pool about 700 feet <br />downstream. Contacts made after 10:15 p.m. indicated that CS741 was very active <br />within a 20 foot area of the eddy pool. This activity continued until 1:15 a.m. on 24 Oct. <br />96 when the fish became mostly inactive. CS741 remained stationary and inactive <br />throughout the remainder of the 24 hour observation. <br />Colorado Squawfish #40:6840 (CS684) <br />CS684 was captured by angling on 27 August 1996 immediately below the sandbar shelf <br />in the upper pool used by CS741 at RM 83.0. Early contacts with the fish suggested that <br />shortly after it was captured and implanted this fish began moving downstream. The day <br />after its release it was located near the submerged bedrock shelves in the pool with <br />CS741 at RM 82.7. Within 12 days CS584 had moved over five miles downstream <br />Draft Yampa River Radio Telemetry Report Page 10 <br />' Miller Ecological Consultants, Inc. December 13, 1996
