each backwater was recorded and a similar haul made along the adjacent <br />river shoreline. The relative abundance of each species within samples <br />was calculated as the number of fish perm sampled by seines. Relative <br />abundance data for each species were averaged within 10-mile river <br />reaches. Data from seining in backwaters and along adjacent shoreline <br />areas were treated separately. <br />Habitat vs Discharge Study <br />The Green River section between Jensen and Ouray, Utah was selected to <br />evaluate effects of altered flows from Flaming Gorge Dam on survival and <br />rearing of YOY Colorado squawfish. Past investigations have shown young <br />Colorado squawfish are common in certain habitats in this river section. <br />Also associated with the flow vs habitat work was an evaluation of flow- <br />time from Flaming Gorge Dam. Key areas at Ouray and Jensen were monitored <br />with staff-gages and photos to determine the timing, duration and magnitude <br />of flooding and dewatering of backwater habitats resulting from daily <br />changes in flow at Flaming Gorge Dam. <br />Using controlled releases of high and low flow from Flaming Gorge, YOY <br />Colorado squawfish were to be monitored to evaluate fish behavior and <br />interactions with other fish species. Young Colorado squawfish were to <br />be marked and followed over the period of study by seining. The response <br />of fishes to temperature and flow changes were studied. Water temperatures <br />and flows were monitored in key habitats at three sites during these <br />investigations. <br /> <br />5 <br />
