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 Ballantyne Lake through the year

Walleye

Spring
Walleye are shallow, on and just off the spawning flats and the first green weeds. In 2.7 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. On a lake that drops to 58 ft, check the deep edge of that structure too.
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. In 2.7 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. On a lake that drops to 58 ft, check the deep edge of that structure too.
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

Lake Ballantyne is a 350-acre lake located in Blue Earth County near the town of Madison Lake. A DNR-owned public access is located on the south shore at the end of 615th Lane. Lake Ballantyne has maximum depth of 58 feet, which can be found in one of the two relatively deep holes in the lake. Most of the lake is comprised of shallower water, with about 81% of the lake less than 15 feet deep. Lake Ballantyne is managed primarily for Walleye and Northern Pike and secondarily for Bluegill, Black Crappie, and Largemouth Bass.

Lake Ballantyne was surveyed the week of 30 June 2025 as part of a regular monitoring program conducted by the Minnesota DNR. This survey consisted of deploying six gill nets and eight trap nets intended to assess the fish population. Water quality parameters were also recorded.

Read the full DNR narrative

Walleye abundance was low during the 2025 survey. Sixteen Walleye were sampled in gill nets for a catch rate of 2.7 fish/net. Walleye catch rates in gill nets have been below 1.0 fish/net in every survey conducted on Lake Ballantyne since 1992 with the exception of 2003. Walleyes sampled in gill nets averaged 13.6 inches and ranged from 8.9 to 20.3 inches. Four year classes were present, 2019 and 2021-2023. The age-3 (2022) year class made up sixty-nine percent of the sample. Trap nets yielded two Walleyes (0.3 fish/net), these fish were 13.7, and 15.4 inches in length. As part of the surplus stocking plan, fingerlings, yearlings and adults have been stocked into Lake Ballantyne in recent years.

Adult Yellow Perch abundance has been low throughout the survey history on Lake Ballantyne. The survey conducted in 2025 was no exception, with gill nets yielding 5.8 fish/net. This catch rate, however, was the second highest recorded on Lake Ballantyne since 1992. Yellow Perch ranged in length from 5.4 to 6.6 inches and averaged 5.8 inches.

Bluegill abundance in Lake Ballantyne had remained relatively stable since 1992. The 2025 catch rate of 16.9/trap net was less than the historic average of 31.7/net. Bluegill lengths ranged from 3.1 to 8.5 inches and averaged 6.6 inches. Otoliths and scales were taken for aging. Bluegills collected ranged in age from 2 to 8 years of age. The most abundant group was the 2022 year-class (age-3). Bluegills reached 6.2 inches at age four, indicating slow to moderate growth.

Black Crappie abundance in Lake Ballantyne has been relatively high in the past three surveys; 22.3 fish/gill net in 2009, 17.8 fish/gill net in 2014 and 15.2 fish/gill net in 2019. In 2025 that number dropped closer to the long term average (9.8/net) with a catch rate of 7.5/ gill net. Black Crappie collected in gill nets ranged in length from 4.1 to 9.7 inches and averaged 6.6 inches, indicating a small size structure. Black Crappie were also collected in trap nets at a rate of 1.1 fish/net. Black Crappies were aged using scales and otoliths. These fish ranged from age-2 to age-12 with 9 age classes present. The youngest four age groups were each represented well, indicating consistent recruitment of Black Crappie. White Crappie are also present in Lake Ballantyne. The 2025 gill net catch rate was 7.8 fish/net, which ranged from 5.9 to 10.0 inches and averaged 6.8 inches in length.

Northern Pike abundance has varied from 0.0 fish/gill net in 1995 to 11.3 fish/gill net in 2000. The 2025 catch rate of 5.0 fish/gill net was greater than the long-term lake average (3.8 fish/gill net). The length of Northern Pike ranged from 18.8 to 34.7 inches and averaged 23.5 inches. The Lake Ballantyne Northern Pike population is sustained through natural recruitment.

The sampling gears typically used in surveys do not effectively capture adult Largemouth Bass. Largemouth Bass were sampled using electrofishing in 2025. Largemouth Bass were sampled at a rate of 45 fish per hour. The Largemouth Bass sampled ranged in length from 3.5 inches to 19.5 inches averaging 10.3 inches. A population estimate of Largemouth Bass was also conducted in the spring of 2025. This produced an estimate of 1,500 Largemouth Bass over 8.0 inches in Lake Ballantyne.

Additional species collected in gill and trap nets in low abundance included Bigmouth Buffalo, Common Carp, Black Bullhead, Yellow Bullhead, Bowfin, and Freshwater Drum.
