declined from a high of 800,657 fish in 1965 to 107,164 fish during 1980. Total harvest increased to 171,370 fish in 1981 and dropped to 161,526 in 1982. METHODS The 1978 and 1982 creel surveys included two independent surveys - one to estimate fishing pressure (aerial census) and one to estimate creel rate, spe- cies composition, party size and length of fishing trip (angler interviews). Fishing pressure estimates were calculated directly from counts of shore and ice fishermen and fishing boats made from a low-flying aircraft. Counts were stratified by zone of the reservoir (Figure 1), weekday or weekend-holiday and type of fishing (boat, shore or ice). Flights were equally divided between weekday and weekend-holiday strata within each month. Eight flight days were scheduled per month. During the months of May through August, two flights were scheduled per count day, for a total of 16 counts per month. The survey was conducted from March 1978 through February 1979. Dates and times of each flight were randomly selected. The 1982 aerial survey was the same as the 1978 survey, except the number of flights (fishermen count sample days) was reduced in 1982 to lower the cost of the survey. Analysis of variance of fishing pressure estimates from the 1978 survey indicated a reasonable level of preci- sion from the reduced sample schedule. Therefore, only four count days were scheduled per month. During the months of May through August, two flights were scheduled per count day for a total of eight counts per month. The holiday weekends of Memorial Day, Fourth of July, and Labor Day were scheduled as separate strata and two count days were scheduled in each of the holiday periods. Two counts were made each day for a total of four counts for each holiday period. # Stratified random angler interviews were conducted according to the schedule developed in 1971 and 1972. Creel survey effort was randomly allocated among all reservoir access points each month and stratified according to weekday or weekend-holiday. There were 18 survey days per month (9 weekday and 9 weekend- holiday days) during the months of January through April and September through December. In the heavy use months of May through August a survey day was broken down into a.m. and p.m. shifts for a total of 36 survey days per month (Table 11). Roving patrols were done either from a boat or by truck depending on the zone and weather conditions. This schedule was followed during the intensive creel surveys of 1978 and 1982. Data collected from each party contacted inclu- ded party size, hours fished, catch by species (including the number of fin- clipped or dye-marked fish in the catch), whether they had finished fishing and in 1979, which species the party was pursuing. Biological data taken from fish in randomly selected creels included length, weight, scales, and/or fin samples as needed. Pectoral fins and scale samples were taken from lake trout in 1979 and 1980. Smallmouth bass stomachs were collected and preserved in formalin in 1982 for analysis of food habits. Analysis of the returns of marked fish, checked during creel surveys, pro- vided data on a host of statistics: movement, survival, longevity, growth and return to the creel. Returns of stocked rainbow trout were calculated from har- vest figures based upon the 4 year mean, while brown trout returns were based upon a 6 year mean. -23-
