Beaver Lake is a good destination for anglers looking for decent crappie and bluegill fishing. Bluegills are reaching 9-inches with good numbers of 7- to 8-inch fish in the 2017 surveys. The older group of 10- to 11-inch black crappie is decreasing in numbers, but still available in good enough numbers to catch some. Behind these fish is a strong year class of 7.5- to 9-inch black crappies that will provide good crappie fishing over the next two to three years. Largemouth bass were sampled in good numbers from 8- to 12-inches and 13.5- to 16-inches. Channel catfish numbers are not high, but sizes are good. The channel catfish surveyed in 2017 were 20- to 28-inches and averaged just over 5lbs.(2017)
