Fish in the 1 – 6 pound range should be common, with some fish nearing 10 pounds. A single large flathead catfish was also collected this year (31.5 pounds and 42.5 inches long). Site regulation: 6 fish daily limit.



Both black and white crappie are present in the lake and the size structure and condition for both of these species are fair.Most crappie in 2021 are expected to be between 6” – 9”, with some fish exceeding 10” and weighing more than ½ of a pound. Crappie fishing should be good in the coming year. Harvest of smaller crappie is encouraged.



The size structure of the largemouth bass population remains good. Average body condition decreased slightly from last year’s sample, and all sizes classes of bass met or exceeded the lake management plan goals. Currently, 25% of the adult bass population exceeds the 14” minimum length limit and 17% of the adult bass are within the 15” – 20” size range.
