Fish Status



The bluegill population is poor. The majority of Bluegill collected have been under 6 inches in length.



A small number of Channel Catfish have been collected during past surveys.


Very Good

Green Wing Lake possesses a quality crappie fishery consisting of both black and white crappie. Seven crappies were collected during the 2021 spring electrofishing survey and an additional 20 were collected during the fall netting survey. Of the 27 crappies collected, 33% were over 10 inches in length.


Very Good

Electrofishing is now a suitable sampling tool at this lake thanks to modernized equipment that can effectively stun fish in high conductivity water. Therefore, an electrofishing survey was conducted during April of 2021. The survey was conducted at night due to the deep, steep-sided nature of the lake, which can limit the efficiency of electrofishing during daylight hours. Results of the survey indicate a quality bass fishery in Green Wing Lake. A total of 32 Largemouth Bass were collected during 20 minutes of electrofishing. Of the bass collected, 53% were at least 15 inches and 13% were over 18 inches in length. Body condition generally increased with length and was excellent by the time bass reached 17 inches, likely due to the abundance of large shad in the lake. The largest bass collected was 7 lbs.

SAUGEYE (Walleye/Sauger Hybrid)


Walleye were stocked annually at this lake from 2002-2020 but were replaced with Saugeye during 2021 and 2022. During the 2022 targeted electrofishing survey, 3 Walleye and 1 Saugeye were collected. Walleye ranged in length from 21-24 inches, while the lone Saugeye in the sample was right at 14 inches. Although the catch rate was below the goal of 10/hour, angler reports suggest that a quality fishery exists.



Walleye stockings occurred annually up until 2020. Survey results indicate a low-density population is still present. Walleye up to 5 lbs. have been captured in surveys during recent years.

Location: Pyramid State Park is located south of Pinckneyville in Perry County. The Denmark Section is accessed off Pyatt-Cutler Road. From State Route 127, head west on Pyatt-Cutler Road. About 7 miles west of Pyramid State Park, turn south into the Denmark Section.

Description: Green Wing Lake is a strip cut lake located on the Denmark Section of Pyramid State Park. Facilities at this 40-acre lake include a concrete boat launch, floating dock, and bathrooms.

History and Status of the Sport Fishery: Thanks to upgraded equipment, electrofishing is now an effective sampling tool for this lake.
The 2021 spring nocturnal electrofishing survey was the first conducted on Green Wing Lake. All fishery information prior to 2021 was based on spring trap net surveys. Another multi-gear community survey is scheduled for 2023.

During 2022, the only fisheries survey conducted was the targeted fall electrofishing survey for Walleye/Saugeye. Catches of Walleye and Saugeye are still very low, suggesting that emigration may be an issue. Past surveys suggest that Green Wing Lake harbors quality angling opportunities for Largemouth Bass and crappie.

Additional Lake Information: Note: There is no motor HP limit, but all boats must be operated at no wake speed.
