Relation Central Utah Project; Western Waters Digital Library; hybrid brown and brook trout the last las t confined mainly to reaches above the proposed taskeech Tas keech reservoir also present are the less popular mountain whitefish and small numbers of kokanee sokanee salmon that were stocked in moon lake the trout fishery is moderately to highly productive except for the 3 mile reach immediately below moon lake reservoir which is watered dewatered dewaterer de annually during the winter however immediately below the dewatered watered dewaterer de area where flows are usually restored by springs and seeps in the proposed taskeech Tas keech reservoir basin the river is considered highly productive for trout in this 3.3 33 33 mile segment standing crop estimates for sport fish showed a high of 121 pounds per acre more than double the amount in other productive reaches of the yellow stone and lake fork rivers reproductive success of sport fish was comparatively low as shown in table B 7 based on percentages of fish sampled that were less than 6 inches in length other considerations however including the high number of naturally produced trout in the sampling and the measured habitat conditions conducive to successful spawning indicated that reproductive success might be considerably greater than shown by the number of young trout in the sampling from the proposed taskeech Tas keech damsite adamsite to the yellowstone river confluence the lake fork river has a moderately productive fishery the average number of pounds of fish per acre drops to 22 significantly less than the yield immediately upstream and reproductive success is slightly diminished from the yellowstone river confluence to the red cap canal about 15 miles downstream the lake fork rivers quality as a fishery is slowly degraded by increasing irrigation return flow the coldwater cold water fishery gradually gives way to warmer water in this reach whitefish and brook trout are not evident and reproductive success is negligible from the red cap canal diversion to the duchesne river the stream is generally slow meandering and highly turbid from irrigation return flow as a result this reach is not a coldwater cold water fishery channel catfish were the only game fish found in any numbers in this section with their standing crop estimated at a low 5 pounds per acre while the estimated standing crop of nongame fish was considerably increased in numbers and species diversity from upstream reaches of the lake fork river comparative analysis indicates that overall the standing trout population in the lake fork river measured in pounds of fish per acre was only about 8 percent of that found in some of the more productive streams elsewhere in the rocky mountain west 4 duchesne river the 26 miles of the duchesne river below the lake fork river confluence are classified as a low quality fishery by the utah B 42
