All year classes above II+ were well represented. Natural reproduction excellent. Quality size fish were abundant in the sample.Bluegill: Net catches of bluegill were high and growth rates are slow. Sixty-three percent of the bluegill were over seven inches in length in the 1969 survey compared with seven percent in 1987. Quality size bluegill appear to have greatly declined.Black Crappie: Net catches of black crappie are fairly high indicating a good population. All year classes are well represented and growth rate is good.Walleye: Walleye catch was low and made up of older fish. No natural reproduction evident during this survey. Stocking records and the 1981 survey indicated good natural reproduction.

Northern pike spawning area dry 1980-1981. Lack of snow and spring rains. Analysis of northern pike and walleye stomachs showed these species to be feeding predominately of bluegills.Test netting results show the northern pike population to be five times the statewide median. The bluegill population is almost eight times the statewide median. The walleye population approximates the statewide median. Largemouth bass and black crappie populations are fair. The yellow perch population is extremely low - none were taken in gillnets and trapnets.
