Rates come from standard DNR survey gear (gill nets, trap nets, electrofishing), judged against statewide benchmarks for the same gear, so the same number of fish per net can read differently for two species. Where the standard gear can't count a species reliably, only presence and size are listed. Typical is the middle fish of those measured. Open a row for the full length spread, survey by survey.
How to fish Green Prairie Fish Lake through the year
Walleye
- Spring
- Walleye are shallow, on and just off the spawning flats and the first green weeds. At 10 ft of clarity, fish them deeper and lighter than usual.
- Early summer
- Walleye are setting up on the outside weed edge, points and shallow structure.
- Summer
- Walleye are working the weed edge, points and any wind-blown structure.
- Fall
- Walleye are packing onto the sharpest breaks and points as the water cools, in big schools with short windows.
Largemouth bass
- Spring
- Largemouth are moving up into the warming bays and flats, staging around wood, docks and new weeds to spawn. At 10 ft of clarity, fish them deeper and lighter than usual.
- Early summer
- Largemouth are on the shallow spawning flats and protected bays, where beds go on firm bottom next to isolated cover.
- Summer
- Largemouth are in and along the weeds: cabbage and milfoil edges, matted cover and shade.
- Fall
- Largemouth are chasing bait back onto the flats and into the remaining green weeds, feeding hard and shallow before the freeze.

Longest fish measured by DNR survey crews in each year's nets. Survey gear samples the population, so the lake usually holds larger fish than any survey measured.

MN DNR · in their words
From the 2025 survey
Green Prairie Fish Lake is an 182-acre lake located approximately 6 miles east of Randall. The lake has a maximum depth of 22 feet with a variety of submerged, emergent, and floating-leaf vegetation near the shoreline. During 2025, the fishing pier located on the southwest side of the lake was extended out from shore to improve fishing opportunities. Spring trap netting was conducted as part of a targeted survey to evaluate the size structure of Bluegill during June 6-11, 2025. This sampling helps to determine if the population has changed following the implementation of a 10-fish bag limit on March 1, 2016. Spring trap netting has been used to survey the panfish on Green Prairie Fish since 2000 and will continue to be used to monitor long-term trends. Black Crappie were also targeted during this survey and were collected while spring trap netting and electrofishing. Otoliths were taken from Black Crappie to evaluate age and growth.
Bluegill size structure goals for the Quality Sunfish Initiative include the persistent presence of fish at least 10 inches in length and at least 50% over 7 inches, 20% over 8 inches, and 5% over 9 inches. Other criteria used to measure the success of the reduced bag limit include mean size, catch rate of fish over 8 inches, and mean length of the top 10%. A total of 505 Bluegill were captured during 2025 and ranged in length from 1.7-9.1 inches (average = 5.8 inches). Fish measuring 10 inches or greater have been absent from all spring trap netting surveys. The current survey showed that 12% of fish were over 7 inches, 1% were over 8 inches, and 0.2% were over 9 inches. The mean length of the top 10% was 7.5 inches and the catch rate of fish over 8 inches was 0.4 fish/net. Lake management plan goals outside of the Quality Sunfish Initiative include maintaining a catch rate of at least 25 fish/net and having at least 25% of the catch exceed 7 inches during spring trap net surveys. In 2025, the catch rate goal was achieved, but the size structure goal was not. Aging data were not collected during 2025, but age analysis from 2017 provided evidence of slow growth. Poor growth is likely limiting the potential for Bluegill to reach larger sizes even if the regulation is reducing the harvest of larger (and older) individuals.

A total of 69 Black Crappie were captured while electrofishing and trap netting, ranging in size from 3.8-11.3 inches (mean = 9.5). The management goal of maintaining 50% of the catch over 9 inches was met during 2025 with 86% over 9 inches. All age groups from 1-5 were present with age-4 fish being the most abundant year class (86%). Black Crappie in Green Prairie Fish Lake have good growth with fish averaging 10 inches by age-4.
A total of 61 Pumpkinseed were collected and ranged in size from 3.1-7.4 inches (average = 6.0 inches) with 16% over 7 inches. One Walleye was captured and measured 25 inches. Five Northern Pike were captured and measured 10.2-15.2 inches. Seven Yellow Perch were caught and ranged in size from 6.0-9.0 inches. Other species captured included Bowfin, Brown Bullhead, Yellow Bullhead, Hybrid Sunfish, and Golden Shiner.
