Improve Walleye and Lake Whitefish Performance Indicators for Lake Level Management – Rainy Lake and Namakan Reservoir

This purpose of this study is to complete a study of Walleye spawning sites on Rainy Lake and of Lake Whitefish spawning sites on Rainy Lake and the lakes of Namakan Reservoir. The project will support improvements to existing lake level performance indicators for these important fish species. Walleye is the most socioeconomically important fish species in the region, and Lake Whitefish are among the fall spawning species predicted to directly benefit from the 2018 Rainy-Namakan Lake Rule Curves. These improved performance indicators will assist the International Rainy-Lake of the Woods Watershed Board in assessing lake level management scenario modeling output, showing performance of existing and alternate rule curves.
