Lake Conservation Webinar Series: Seasonal Habitat, Temperature, and Depth of Adult and Juvenile Ogaa in Mille Lacs Lake
In 2018, the Mille Lacs Band of Ojibwe fisheries department deployed 61 acoustic receivers in Mille Lacs Lake to track tagged adult and juvenile walleye. In recent years, the ogaa stock has declined, which we hypothesized is due to less cool water for walleye to seek refuge over the summer. In this experiment, we analyzed depth and temperature data from both life stages of walleye. We found significant overlap in location, temperature, and depth during the month of January. We also identified areas of key walleye importance on Mille Lacs Lake.
