DNR fish survey, 2025
Temperature and dissolved oxygen measurements were collected from the deepest basin in Little Hanging Horn Lake on August 22nd, 2025. This was done 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 in this lake. Cisco requires 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 data collected from the deepest basin (maximum sampled depth was 68.9 feet), the water temperature decreased to 21.2 degrees C (70.2 degrees F) at 11.0 feet, and the dissolved oxygen concentration decreased to 3.0 mg/L at 17.4 feet at the time of sampling. This layer in the water column was 6.4 feet deep, indicating that oxythermal habitat for Cisco was present. Further, the temperature at which dissolved oxygen decreased to 3.0 mg/L (i.e., TDO3, a single variable to characterize oxythermal habitat) was 13.3 degrees C (55.9 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 period of maximum oxythermal stress (July 26th to Aug 24th) in 2024 also indicated a suitable oxythermal habitat, measuring 4.0 feet deep. When adequate oxythermal habitat is not available, Cisco are squeezed into unfavorable, warmer water conditions and experience higher levels of stress.
