No recent survey rating

No recent survey rating.

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 Sauk 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 61 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 61 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

Sauk (Big Sauk) Lake (DOW# 77-0150-00; Lake Class 25) is a 2,126-acre lake that extends north of the Sauk Centre Dam. The lake has a maximum depth of 61 feet, an average depth of 17 feet, and water visibility around 6 feet. Sauk Lake has a variety of submerged, emergent, and floating-leaf vegetation around its perimeter. The lake is primarily managed for Walleye and Bluegill, and secondarily for Largemouth Bass, Northern Pike, and Black Crappie. Walleye fry are stocked to maintain the population within or above management goals. A targeted electrofishing survey for young-of-year Walleye was completed on September 9, 2025. Fall electrofishing surveys are used to evaluate fry stocking success or natural reproduction. A total of 1.4 million fry were stocked in the spring of 2025.

Fall night electrofishing has been conducted annually on Sauk Lake since 2009 to assess the relative abundance of young-of-year Walleye. This sampling is used to evaluate fry stocking success or natural reproduction during years without stocking. Over the years, electrofishing surveys have been useful predictors of future gill net catches. The catch rate young-of-year Walleye during 2025 was 7.0 fish/hour, which is the lowest on record for Sauk Lake. Catch rates prior to 2025 have ranged from 10.9 fish/hour (2010) to 127.5 fish/hour (2011. Young-of-year Walleye captured during 2025 ranged in size from 5.1-6.3 inches (average = 5.7 inches). This was slightly smaller than the average length (6.6 inches) from all previous surveys. Age analysis has shown that fish reach 13.6 inches by age-2, 16.7 inches by age-3, 17.7 inches by age-4, and 20.3 inches by age-5.

Read the full DNR narrative

Natural reproduction has been documented during fall electrofishing surveys and from aging fish captured in gill nets. Prior to 2000, there was little to no evidence of natural reproduction in Sauk Lake. Notable natural year classes were eventually documented in 2000 and 2007 during summer surveys. More recently, year classes of natural fish have been reported for 2020 and 2023. Therefore, it is important to consider that fall electrofishing catches may be comprised of both stocked and natural fish during stocking years.

Several other species were observed during the 2025 fall electrofishing survey. Yellow Perch and Bluegill were notably abundant throughout the sites. Shiners and minnows were also abundant. White Sucker and Shorthead Redhorse were present in low abundance. Smallmouth Bass, Largemouth Bass, and Northern Pike were all observed.
