Spring

Temperature and dissolved oxygen measurements were collected in the deepest basin in Spring Lake on August 1, 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 also present). During the summer, 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 19.7 feet and the dissolved oxygen concentration decreased to 3.0 mg/L at 41.5 feet at the time of sampling. The thickness of this layer of water in the water column was 21.9 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 7.6 degrees C (45.7 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 the survey. Data collected by the Minnesota Department of Natural Resources during the late summer period of maximum oxythermal stress in 2019, 2016, 2014, and 2009 also indicate suitable oxythermal habitat in all years. When inadequate oxythermal habitat is available, Lake Whitefish are squeezed into unfavorable, warmer water conditions and experience higher levels of stress.
