Beaver Lake is a good option for anglers looking for good crappie and bluegill fishing. Bluegills were surveyed in 2022 in fair numbers from 7- to just over 8-inches. There is a good group of 9-to 10-inch Black Crappies with fish up 11.5-inches observed. Largemouth Bass were sampled in good numbers from 12- to 14.5-inches. Channel Catfish numbers are not high, but sizes are good. Most Channel Catfish are 20- to 29-inches. There is a small population of Yellow Perch at sizes from 7.5- to 8.5-inches.(2022)
