DNR fish survey, 2025
A temperature-dissolved oxygen (TDO) profile was collected on 8/6/2025 to measure the amount of thermal habitat available for Tullibee. The TDO3 (temperature at 3 mg/l dissolved oxygen) was determined to be 5.8 degrees C and comparable to previous assessments. While water from the surface to about 17 feet was warm, overall oxy-thermal habitat was good for Tullibee from the surface to a depth of 99 feet. Data collected from 2009-2025 indicate abundant thermal habitat for Tullibee in most years, with the worst conditions recorded in 2009 and 2010, and the best in 2023. The lake provides "good" habitat compared to other lakes in the Aitkin management area that are monitored for Tullibee habitat. Because the area is located near the southern edge of Minnesota's Tullibee range, TDO profiles should continue to be collected to monitor the availability of cold-water habitat.
