East Bearskin

Temperature and dissolved oxygen (DO) measurements were collected from the deepest basin in East Bearskin Lake on August 6th, 2024, to evaluate the quantity and quality of cold, oxygenated water (i.e., oxythermal habitat) available to Lake Trout, the most sensitive coldwater species present in this lake. During the summer, Lake Trout require a layer of oxythermal habitat that contains water temperatures below 8.8 degrees C (47.8 degrees F) and dissolved oxygen concentrations above 3.0 mg/L. Based on the profile from the deepest basin (maximum sampled depth 65.6 feet), the water temperature decreased below 8.8 degrees C (47.8 degrees F) at 59.0 feet and the dissolved oxygen concentration decreased to 3.0 mg/L at 57.2 feet at the time of sampling. Therefore, the water column did not contain a layer of water with sufficient temperature and dissolved oxygen for Lake Trout. Further, the temperature at which dissolved oxygen decreased to 3.0 mg/L (i.e., TDO3, a single variable to characterize oxythermal habitat) was 8.9 degrees C (48.0 degrees F). TDO3 values warmer than 8.8 degrees C (47.8 degrees F) indicate that oxythermal conditions were unsuitable for Lake Trout 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 9 years, between 1956-2023, indicate suitable oxythermal habitat in most years when surveyed, with the least favorable conditions recorded in 2024. When inadequate oxythermal habitat is available, Lake Trout are squeezed into unfavorable, warmer water conditions and experience higher levels of stress.
