DNR fish survey, 2025

Temperature and dissolved oxygen (DO) measurements were collected from the deepest basin in LaSalle Lake on August 5th, 2025, to evaluate the quantity and quality of cold, oxygenated water (i.e., oxythermal habitat) available to 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. Based on the profile from the deepest basin (maximum sampled depth 167.3 feet), the water temperature decreased below 21.2 degrees C (70.2 degrees F) at 17.1 feet and the dissolved oxygen concentration decreased to 3.0 mg/L at 35.0 feet at the time of sampling. The thickness of this layer of water in the water column was 17.9 feet, indicating that oxythermal habitat was present 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 6.1 degrees C (43.0 degrees F). TDO3 values cooler than 21.2 degrees C (70.2 degrees F) indicate that oxythermal conditions were suitable 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 Aug 24th) in 4 years, between 2010-2017, also indicate suitable oxythermal habitat in all years surveyed. When inadequate oxythermal habitat is available, Cisco are squeezed into unfavorable, warmer water conditions and experience higher levels of stress.
