DNR fish survey, 2025

Temperature and dissolved oxygen measurements were collected from the deepest basin in Pimushe 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. During this survey, TDO3 was 21.6 degrees C (70.9 degrees F), which indicates that oxythermal conditions were unsuitable for coldwater species 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 2008 indicated unsuitable oxythermal habitat, when the oxythermal habitat layer was not present. However, a survey completed in 2024 did indicate marginal habitat for Cisco, with a TDO3 of 20.5 degrees C. When inadequate oxythermal habitat is available coldwater species are squeezed into unfavorable, warmer water conditions and experience higher levels of stress.
