Taylor Draw Dam is located at RK 167.8, 16 km east of Rangely, Colorado. <br /> <br />Fingerling Colorado squawfish were present <br />in schools with other small fish. Large schools <br />were composed of as many as seven species, in- <br />cluding Colorado squaw fish, roundtail chub ( Gila <br />robusta), flannelmouth sucker (Catostomus lati- <br />pinnis), fathead minnow (Pimephales promelas), <br />red shiner (Cyprinella lutrensis), carp (Cyprinus <br />carpio), and black crappie (Pomoxis nigromacu- <br />latus) . <br />Colorado squawfish distribution in the reser- <br />voir after the first two months following stocking <br />was unknown, because few fish were caught (Fig. <br /> <br />2). Only four fish were caught in their second <br />summer (age 2) in the reservoir. These fish were <br />collected in gill nets set at depths of 4.5 to 6 m <br />near cliffs or steep shoreline areas. <br />Colorado squaw fish were collected below the <br />dam within two days of stocking. Colorado <br />squawfish emigration from the reservoir was high, <br />although no precise estimate of the numbers was <br />possible. Of all squaw fish collected, the percent- <br />age caught below the dam varied from 18.5 to <br />45% (Table 3), but total escapement was believed <br />to be much higher.
