Average | The 2023 survey showed high numbers of bluegill that are below the desire size distribution. Body condition of the bluegill collected was poor. This is not uncommon in a lake dominated by Gizzard shad. | |
Very Good | This species is solid in this lake. Good numbers and size quality were present in the 2023 survey. Site regulation: 6 fish daily creel limit. | |
Good | This trophy species is stocked into Lake Glen Shoals by IDNR at 2” in length. During the past few surveys, quite a few quality fish were seen. All but a few were over the legal limit. Site regulation: 17” minimum length limit; 3 fish daily creel limit. | |
Improving | The largemouth bass numbers are up from the previous survey, but still remain lower than the target. The bass collected in the 2023 survey showed good size distribution and body condition. 4-7" bass are stocked annually in an effort to improve numbers. Site regulation: 15” minimum length limit; 3 fish daily creel limit. | |
Very Good | Good numbers of White crappie were collected in the 2023 survey. The white crappie collected were of good size, with many over 10+11 inches, but plenty of up and comers in ranges below the 10" mark. | |
