Beaver Lake is a good destination for anglers looking for decent crappie and bluegill fishing. Bluegills were surveyed in 2018 in good numbers from 7- to 8-inches. There is a large group of 9-to 11-inch black crappies with a younger year class of 6- to 7-inch fish following up. Largemouth bass were sampled in good numbers from 9- to 16-inches. Channel catfish numbers are not high, but sizes are good. The channel catfish were 20- to 28-inches and averaged just over 5 pounds.(2019)
