Stocking history
| Year | Species | Size | Number | Pounds |
|---|---|---|---|---|
| 2024 | Walleye | fingerlings | 1,400 | 200.0 |
| 2023 | Walleye | fry | 200,000 | 1.8 |
| 2022 | Walleye | fingerlings | 2,720 | 218.0 |
| 2021 | Walleye | fingerlings | 1,896 | 158.0 |
| 2019 | Walleye | fry | 200,000 | 1.7 |
| 2018 | Walleye | fingerlings | 611 | 116.5 |
| 2017 | Walleye | fry | 105,000 | 0.9 |
| 2016 | Walleye | fingerlings | 4,000 | 160.0 |
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.

DNR fish survey, 2024
Temperature and dissolved oxygen measurements were collected from the deepest basin in Long Lake on August 15th, 2024, to evaluate the quantity and quality of cold, oxygenated water (i.e., oxythermal habitat) available to Cisco, also known as Tullibee, the most sensitive coldwater species present in this lake. During the summer, Cisco require a layer of oxythermal habitat that contains water temperatures below 21.2 degrees C (70.2 degrees F) and dissolved oxygen concentrations above 3.0 mg/L. Based on the profile from the deepest basin (maximum sampled depth 47.9 feet), the water temperature decreased below 21.2 degrees C (70.2 degrees F) at 20.0 feet and the dissolved oxygen concentration decreased to 3.0 mg/L at 21.8 feet at the time of sampling. The thickness of this layer of water in the water column was 1.8 feet, indicating that oxythermal habitat was present but marginal for Cisco. Further, the temperature at which dissolved oxygen decreased to 3.0 mg/L (i.e., TDO3, a single variable to characterize oxythermal habitat) was 20.1 degrees C (68.2 degrees F). TDO3 values cooler than 21.2 degrees C (70.2 degrees F) indicate that oxythermal conditions were present but marginal for Cisco at the time of the survey as the layer was confined to less than 3 feet of suitable habitat at the time of the survey. Data collected by the Minnesota Department of Natural Resources during the late summer period of maximum oxythermal stress (July 26th to Aug 24th) in 1993 and 2006 indicate unsuitable oxythermal habitat across both years, with the least favorable conditions recorded in 2006 when the suitable oxythermal habitat layer was 0 feet thick. When inadequate oxythermal habitat is available, Cisco are squeezed into unfavorable, warmer water conditions and experience higher levels of stress.
