Fish Status |
Good | The size structure of the bluegill population remains stable. Bluegill will be abundant in the coming year with most keepers measuring 7- 8" in length and weighing up to 1/3 lb. A few bluegill over 8 inches were collected in the 2024 survey. | |
Excellent | The fishing prospects for channel catfish remain excellent for 2025. Natural reproduction and recruitment continue to be very strong, and are responsible for maintaining the large population of fish in the lake. In the coming year, channel catfish from 1 – 3.5 pounds should be abundant with larger fish up to 5 pounds common. This lake remains one of the premier channel catfish waters in southern Illinois, and should remain on your list of places to fish for channel catfish in 2025. | |
Good | Fall 2024 sampling indicated that the portion of the crappie population comprised of fish over 10” in length is 17%. Another 19% of the crappie collected were between 9-10 inches. The number of crappie over 12” in length remains stable and relatively low. Two percent of the crappie collected in the 2024 survey were over 12 inches. Site Regulation: White, Black or Hybrid Crappie: 25 daily limit, not more than 10 exceeding 10". | |
Good | Seven flathead catfish were collected in the 2024 survey ranging in size from 5-18 inches in length with the largest weighing 2.6 pounds. | |
Fair | Six striped bass hybrids were collected in the 2024 fall survey. The hybrids collected were 13-14 inches in length. Anglers can also target these hybrid stripers in the spillway area in the spring. Site Regulation: 20 daily limit, not more than 3 exceeding 17" | |
Good | The bass population for 2024 will be good. Based on the 2024 fall survey, the percentage of the population exceeding the 14" minimum length limit was 24%. Another 8% of the bass population were between 12-14 inches or just below the 14 inch length limit. The number of larger bass over 18" in length remains stable but low. Six percent of the bass collected in the 2024 survey were over 18 inches. The largest bass collected was 6.3 pounds. Site Regulation: 6 fish daily limit, 14" minimum length limit. | |
Good | During the 2024 survey, white bass were collected at a rate of 12 fish/hr which was equal to the 5-year average. White bass fishing should be good in 2025. Anglers can expect the catchable population to be largely comprised of fish 10”- 15” in length and weighing 0.5 – 1.5 pounds. Site Regulation: 20 daily limit, not more than 3 exceeding 17". | |
