2012Rates 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 Lake through the year
Largemouth bass
- Spring
- Largemouth are moving up into the warming bays and flats, staging around wood, docks and new weeds to spawn.
- 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.
Walleye
- Spring
- Walleye are shallow, on and just off the spawning flats and the first green weeds.
- 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.

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.

From the 2025 survey
Crappie were collected as part of a broad research project investigating populations across Minnesota. Springtime trap net surveys collected a total of 241 fish. Individuals averaged 9.1 inches with the largest individual being 11.4 inches. Growth was moderate and individuals averaged 7.6 and 9.8 inches at age 3 and 6, respectively. Maximum age was 12.
A research survey collected Black Crappie as part of a broad statewide research project investigating population demographics and dynamics across Minnesota. Fish were collected using springtime trap nets targeting pre-spawn feeding patterns. A total of 241 fish was collected in the spring of 2025. Average and maximum total length was 203 and 287 mm, respectively. Age distribution extended from 2 to 12 with variable year class formation (3 missing cohorts). A von Bertalanffy growth curve was fit (Linfinity = 262 mm, K = 0.57, t0 = 0.71) and indicated moderate growth rates. Average total length of age-3 and age-6 individuals was 191.3 and 249.6 mm, respectively. Recruitment was irregular (RVI = 0.21, RCD = 0.11). Total annual mortality was estimated using a weighted catch curve (A = 0.24; 95 CI = 0.19 to 0.29). An estimate of total annual mortality exceeds the approximates the first quartile of mortality rates (A = 0.23) in similar Minnesota lakes
