Stocking history
| Year | Species | Size | Number | Pounds |
|---|---|---|---|---|
| 2023 | Black Crappie | adults | 13 | 4.3 |
| 2018 | Walleye | fry | 1,787,715 | 17.5 |
| 2016 | Walleye | fry | 1,000,000 | 9.4 |
Field note · Minnesota stocks by year, not by truck day: walleye fry go in within weeks of ice-out, fingerlings and yearlings mostly in fall, and stream trout in spring and fall. A row here means the fish went in during that year; DNR adds the year's rows after the fact, so the current year can look empty until winter.

Catch per net (CPUE) is the DNR survey's count per gill net or trap net set; higher means more of that species were sampled, not a fishing forecast. Top species per gear shown; where we have no verified common name for a DNR code, the code itself is shown.
A standard survey was conducted on Long Lake during late June of 2025. A targeted survey is generally used for sampling a specific kind of fish or time of year (i.e. spawning season, fall season, etc.) unlike a standard survey which samples a wider range of fish species during the summer months using standard methodology (i.e. standard time of year, set sampling stations, taking water clarity readings and oxygen/temperature profiles, etc.) and gears (i.e. lake survey gillnets, trapnets and possibly spring electrofishing for Largemouth Bass). An Index of Biotic Integrity "FIBI" targeted survey for all near shore fish species was last conducted in August of 2020. A Score The Shore survey "STS" was last conducted in 2021. A targeted spring night electrofishing survey was conducted for yearling Walleye on Long Lake during April 23, 2025. Long is a large (1,568 acres), shallow (16 feet maximum depth), aerated, and productive lake located in Kandiyohi County. Long is part of the Hawk Creek Watershed. The watershed is varied with undeveloped hardwoods, agricultural row crops, grasslands, wetlands, and residential development. There are two public access sites located along the lake (northeast, southwest). Zebra Mussels were first reported in Long Lake during 2022. The water clarity was excellent for Long Lake on June 23, 2025 (secchi=9.0 feet). Water clarity averaged 7.7 feet for May-October of 2025. Blue-green algae blooms are common during the mid-to-late summer periods in Long Lake. The nutrient levels were high for Long Lake during late July of 2021 (total phosphorus=0.096 ppm). Submergent vegetation consists primarily of sago pondweed, coontail and narrow-leaf pondweed group. Filamentous and blue-green algae also occur in Long Lake. Emergent vegetation stands were scattered along the lakeshore. Emergent vegetation consisted primarily of hardstem bulrush and cattail species. There are several mid-water bulrush islands in Long Lake. Shoalwater substrates are primarily sand, gravel, boulder, silt and rubble. A cormorant rookery is located on the large island. There are fourteen small inlets and one large inlet (Ringo Lake Outlet) that enter Long Lake. The Long Lake outlet connects to East Solomon Lake. Water levels were low during the spring, but high by summer and early fall of 2025. The DNR Spicer Area Fisheries Office manages Long Lake for Walleye, Northern Pike, Bluegill, Black Crappie, Yellow Perch, and Largemouth Bass. Black Crappie abundance was low in 2025 (0.42 fish/trapnet). The Black Crappie historical average catch rate is 2.71 fish/trapnet for…
