Stocking history
| Year | Species | Size | Number | Pounds |
|---|---|---|---|---|
| 2023 | Walleye | fry | 500,000 | 4.1 |
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, 2025
Temperature and dissolved oxygen measurements were collected from the deepest basin in Wolf Lake, which is located partially within the Leech Lake Reservation, on August 7th, 2025, to evaluate the quantity and quality of cold, oxygenated water (oxythermal habitat) available to coldwater fish species such as 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. This layer can be characterized using a single variable, TDO3, the temperature at which dissolved oxygen decreased to 3.0 mg/L. Based on data collected from the deepest basin (maximum sampled depth was 55.8 feet), the water temperature decreased to 21.2 degrees C (70.2 degrees F) at 19.5 feet and the dissolved oxygen concentration decreased to 3.0 mg/L at 19.0 feet at the time of sampling. Therefore, the water column did not contain a layer of water with sufficient temperature and dissolved oxygen 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 21.5 degrees C (70.7 degrees F). TDO3 values warmer than 21.2 degrees C (70.2 degrees F) indicate that oxythermal conditions were unsuitable for Cisco 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 August 24th) in 2009 indicated suitable oxythermal habitat with a layer of 8.3 feet. However, surveys in 2019 and 2024 indicated marginal (i.e., 2.9 feet) or no suitable habitat, respectively. When inadequate oxythermal habitat is available, Cisco are squeezed into unfavorable, warmer water conditions and experience higher levels of stress.
