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 Stony Lake through the year

Northern pike

Spring
Pike are in the shallow bays and along new weed growth. At 22.8 ft of clarity, fish them deeper and lighter than usual.
Early summer
Pike are on the outside weed edge and points.
Summer
Pike are on the deep weed edge and points near the coolest water they can find. On a lake that drops to 50 ft, check the deep edge of that structure too.
Fall
Pike are on the last green weeds and the breaks beside them, feeding heavily as the water drops.

Walleye

Spring
Walleye are shallow, on and just off the spawning flats and the first green weeds. At 22.8 ft of clarity, fish them deeper and lighter than usual.
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 50 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.

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 2023 survey

Stony Lake is a 563-acre lake with 6.58 miles of shoreline and a maximum depth of 50 feet located east of Hackensack, MN. A Minnesota Department of Natural Resources (MNDNR) owned public access is located on the south shore. The DNR has classified Minnesota's lakes into 43 different classes based on physical, chemical, and other characteristics. Stony Lake is in Lake Class 23; lakes in this class are generally deep and very clear lakes. Other Lake class 23 lakes in the Walker Area include Mule, Man Horseshoe, and Long lakes. Stony Lake possesses a highly developed shoreline. The lake is primarily managed for Walleye and Smallmouth Bass and secondarily for Black Crappie, Largemouth Bass, Northern Pike, and Yellow Perch.

Walleye abundance failed to meet the long-range management for the third consecutive survey. Walleye lengths ranged from 12 to 28 inches with a mean length of 18 inches. Northern Pike are abundant, exceeding the maximum management goal the past 2 surveys. Sampled pike ranged in length from 9 to 38 inches with a mean length of 19 inches. Black Crappie abundance and size met long-range management goals, and lengths ranged from 5 to 12 inches with a mean length of 10 inches. Bluegill abundance was similar to recent surveys and lengths ranged from 3 to 10 inches. Largemouth Bass ranged in length from 5 to 15 inches. Yellow Perch abundance has remained below management goals since 2005.

Other fish sampled in Stony Lake included, Hybrid Sunfish, Pumpkinseed, Rock Bass, Smallmouth Bass, White Sucker, and Yellow Bullhead.

People can have significant impacts on lakes and the fish populations they support. Harvest, lakeshore development, removal of shoreline vegetation, and introductions of invasive species can all adversely affect fish populations. Currently, no aquatic invasive species (AIS) have been identified in Stony Lake. AIS are moved from infested to non-infested waters by anglers, boaters, and lake shore owners and can adversely impact lakes and fish populations. To avoid spreading AIS, lake users are required to remove all aquatic plants or animals from their watercraft and drain all water from their boat before leaving the access. If you suspect an infestation of an invasive species in this lake, save a specimen and report it to a local natural resource office. Additional information on all of these topics can be found on the DNR website (www.dnr.state.mn.us) or by contacting the Walker Area Fisheries office.
