r Considerable size variation was evident among all species harvested (Tables 22 and 23). Lake trout were consistently the largest of all species harvested, except in the Inflow Area during 1978. Mean lengths and weights of lake trout increased dramatically in the Inflow from 1978 to 1982 and surpassed the brown trout in 1982. Generally, average lengths and weights were the largest for all species in the open Hills, with the exception of brown trout in 1978. Brown trout are stocked only in the Inflow Area and usually adult fish dominate the catch in the Canyon. The decrease in mean lengths and weights of brown trout in the Inflow and Open Hills in 1982 can be attributed to the large numbers of brown trout planted in 1980 and 1981. Smallmouth bass were the smallest of all sport fish harvested in the reservoir. Mean lengths and weights of rainbow trout for the reservoir as a whole remained the same during the project period. The mean length and weight of kokanee salmon harvested from Flaming Gorge was considerably larger than the mean length and weight of the average rainbow trout harvested. A summary of the monthly harvest and creel rates (Table 24) from Flaming Gorge during 1982 indicate mean harvest and creel rates increase to and peak during the month of July. Harvest then declines through the remainder of the year with minor increases in September and November. Catch rates decrease from the July peak until October, when catch rates increased and then remained unchanged for the rest of the year. Fishing in the Canyon peaks in July. June is the peak month in the Open Hills. Fishing in the Inflow Area peaks in May and November with the best fishing during the month of November. Harvest esti- mates show that 23 percent of the brown trout harvest during 1982 occurred in November, while the months of May, June, and July account for 41 percent of the total lake trout harvest. Flaming Gorge Reservoir yielded an average of 4.7 pounds/surface acre during the project period (Table 25). The estimates range from a low of 3.46 pounds/surface acre during 1981 to a high of 5.36 pounds/surface acre during 1978 and 1979. Schmidt et al. (1980b, 1982a, and 1982b) analyzed fishing effort directed at each species of game fish and creel rates obtained from anglers fishing for par- ticular species on Flaming Gorge. The majority of the fishing effort during the study period was directed toward small trout, primarily rainbow trout. Nearly all shore fishing is directed towards small trout, while boat fishing pressure is directed towards several species. These include the categories headed by rainbow trout and lake trout. Fishing for trophy brown trout has subsided since 1979, while interest in trophy lake trout fishing has increased since 1979. Anglers fishing specifically for smallmouth bass and small trout have the highest catch rates. Fishermen fishing specifically for the lake trout and brown trout have the lowest catch rates. Fishing for trophy species has lowered the mean catch rate for all species of fish in the reservoir. The car counter data collected during the 1982 intensive creel 'survey was analyzed by Steve Yundt, Fish Population Biologist, Wyoming Game and Fish Department, Laramie, Wyoming. A multiple regression model was developed using the car count information from the eight car counters located in Wtoming and Utah on a monthly basis. The monthly car counts were regressed against esti- mated monthly fishing pressure. Using the Lucerne and Sheep Creek car counters, the coefficient of determination (r2) was calculated to be 0.91.
