DNR fish survey, 2024
Temperature and dissolved oxygen profiles were collected in the deepest basin in Island-Loon Lake on August 14, 2024, to evaluate the quantity and quality of cold, oxygenated water (i.e., oxythermal habitat) available to Lake Whitefish, the most sensitive coldwater species present in this lake (Cisco are also present). Lake Whitefish require a layer of oxythermal habitat that contains water temperatures below 17.2 degrees C (63.0 degrees F) and dissolved oxygen concentrations above 3.0 mg/L. Based on the profile from the deepest basin, the water temperature decreased to below 17.2 degrees C (63.0 degrees F) at 21.8 feet and the dissolved oxygen concentration decreased to 3.0 mg/L at 28.4 feet at the time of sampling. The thickness of this layer of water in the water column was 6.6 feet, indicating that oxythermal habitat was present for Lake Whitefish. Further, the temperature at which dissolved oxygen decreased to 3.0 mg/L (i.e., TDO3, a single variable to characterize oxythermal habitat) was 11.8 degrees C (53.2 degrees F). TDO3 values cooler than 17.2 degrees C (63.0 degrees F) indicate that oxythermal conditions were suitable for Lake Whitefish at the time of this survey. Data collected by the Minnesota Department of Natural Resources in 2022-2023 during the late summer thermal stress period, also indicated suitable oxythermal habitat, with the least favorable conditions recorded in 2024. When inadequate oxythermal habitat is available, Lake Whitefish are squeezed into unfavorable, warmer water conditions and experience higher levels of stress.
