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 Upper South Long Lake through the year

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. On a lake that drops to 47 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.
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 47 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.

MN DNR · in their words

From the 2025 survey

Upper South Long is an 804 acre lake 10 miles southeast of the city of Brainerd in Crow Wing County. Walleye is the primary management species, with the lake being stocked every other year (odd years) with 283 pounds of fingerlings. When surplus Walleye fry are available, up to 300,000 may be stocked; this last occurred in 2025. Northern Pike, Largemouth Bass, and Black Crappie are other species managed on this lake. A standard survey using gill nets, trap nets, and spring electrofishing was conducted in July 2025 to assess fish populations and provide angler information.

The Walleye numbers (2.3 per net) were the highest since 1999. With 57% of the fish measuring over 15 inches and fish up to 28.3 inches sampled, anglers should have a good chance for some quality fish.

Read the full DNR narrative

The Northern Pike numbers (1.6 per net) were the lowest since 1994. Upper South Long is lacking the typical "hammer handle" population that many of the area lakes possess. With fish measuring 21.9 to 29.9 inches, anglers have a great chance at some medium size pike.

The Largemouth Bass population still looks good, even with night electrofishing numbers (60 fish per hour) down from last time. A broad range of sizes was captured, with fish ranging from 4.4 to 18.9 inches. With 57% of the fish measuring over 14 inches, there is potential to catch nice fish.

Panfish numbers were average for this type of lake, but size didn't offer much for anglers. Only 14% of the Bluegills were over 7 inches and only 31% of the Black Crappies were over 8 inches. Bluegill maxed out at 8.2 inches and the largest Black Crappie was 10.9 inches.

Other fish species sampled included Bowfin (Dogfish), Brown Bullhead, Greater Redhorse, Hybrid Sunfish, Pumpkinseed, Rock Bass, Tullibee (Cisco), White Sucker, Yellow Bullhead, and Yellow Perch.
