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 Greenleaf Lake through the year

Walleye

Spring
Walleye are shallow, on and just off the spawning flats and the first green weeds. In 2 ft of visibility, they sit shallower than you think.
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. With 87% of this lake 15 ft or shallower, the weed edge is the main event.
Fall
Walleye are packing onto the sharpest breaks and points as the water cools, in big schools with short windows. A 19-ft bowl cools fast, so the fall window comes early here.

Largemouth bass

Spring
Largemouth are moving up into the warming bays and flats, staging around wood, docks and new weeds to spawn. In 2 ft of visibility, they sit shallower than you think.
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. With 87% of this lake 15 ft or shallower, the weed edge is the main event.
Fall
Largemouth are chasing bait back onto the flats and into the remaining green weeds, feeding hard and shallow before the freeze. A 19-ft bowl cools fast, so the fall window comes early here.

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 2024 survey

Greenleaf Lake is a 302-acre lake located approximately 3.5 miles southwest of the town of Montgomery in Le Sueur County. The DNR-owned public access is located on the northeast shore off County Road 140. Greenleaf Lake has a maximum depth of 19 feet, with approximately 87% of the lake less than 15 feet deep. Greenleaf Lake is primarily managed for Bluegill and Walleye and secondarily for Black Crappie and Largemouth Bass. The management plan calls for stocking Walleye fry at a rate of 1,000 fish/littoral acre in odd years. Recent stocking events include fry in 2019, 2021, and 2023. Periodic winterkills were common before the installation of an aerator in 1983. Since that time, winterkills had not been a factor until 2019 when a near complete winterkill took place. High levels of phosphorus have contributed to poor water quality and extensive algae blooms that result in poor water quality. The lack of aquatic vegetation remains a challenge for managing stable game fish populations.

Greenleaf Lake was surveyed the week of 8 July 2024 as part of a regular monitoring program conducted by the Minnesota DNR. This survey was intended to assess the fish community by deploying 6 gill nets, 9 trap nets, and 44 minutes of boat electrofishing as well as recording water quality parameters.

A total of 480 Bluegills were sampled with trap nets for a catch rate of 53.3/net. Since 1984, catch rates have varied from 3.3/net to 142.0/net with an average of 34.2/net. Bluegills ranged from 3.3 to 8.3 inches with an average of 7.1 inches. Bluegills were aged using scales and otoliths and ranged from 1 to 5 years old with 5 year-classes present. Three and four year old Bluegills accounted for approximately 80% of the sample.

A total of 5 Walleyes were sampled with gill nets for a catch rate of 0.8/net. Walleyes ranged from 12.0 to 16.5 inches. Walleye were abundant in trap nets during the 2021 survey and it is not clear what caused numbers to drastically decline between surveys.

Yellow Perch were the most common non-bullhead species sampled with gill nets in 2024. A total of 440 Yellow Perch ranging from 5.6 to 9.1 inches were sampled for a catch rate of 73.3/net. Broodstock Yellow Perch were stocked in 2019, and natural reproduction has been successful.

Black Bullheads dominated the gill net catches in 2024. A total of 705 were sampled with gill nets for a catch rate of 117.5 per net which was a decrease from 202.4/net in 2021. Since 1984, catch rates have varied from 8.0/net in 1994 to 274.0/net in 1985 with an average of 111.2/net. Bullheads ranged from 4.7 to 15.9 inches with an average of 7.7 inches. Black Bullheads thrive in unstable and hypereutrophic systems like Greenleaf Lake. Even with the aerator, the fish community will likely remain dominated by tolerant species such as Black Bullheads and Common Carp.

A total of 28 Common Carp ranging from 7.5 to 26.5 inches were sampled with gill nets for a catch rate of 4.7/net. Since 1984, catch rates have varied from 0.0/net in 1985 to 48.3/net in 2006 with an average of 11.5/net. Like Black Bullheads, Common Carp are adept at surviving in lakes like Greenleaf Lake. Unfortunately, efforts to reduce populations of Common Carp and Black Bullhead have largely been unsuccessful in lakes like Greenleaf Lake. It is also possible that aeration allows them to remain at high numbers when they would otherwise suffer losses during winterkills.

Thirty-two Largemouth Bass were sampled with boat electrofishing for a catch rate of 43.7/hour. The 2023 catch rate was slightly lower than the 2021 catch rate of 52.6/hour. Largemouth Bass ranged from 4.3 inches to 15.2 inches and averaged 7.5 inches.

Other species sampled in 2023 include Golden Shiner and White Sucker.

Shoreline property owners also play an important role in the overall health of an aquatic ecosystem, including the fish population. Natural shorelines, including vegetation, woody debris, and bottom substrates, provide valuable habitat for fish and wildlife, help maintain water quality, and reduce bank erosion. By leaving natural shorelines unaltered or restoring them to natural conditions, shoreline property owners are doing their part to maintain or improve a healthy ecosystem in the lake and protect the resource for future generations.
