International Rainy-Lake of the Woods Watershed Board

The International Rainy-Lake of the Woods Watershed Board (the Board) was created in January 2013, from an amalgamation of the International Rainy Lake Board of Control and the International Rainy River Water Pollution Board, with added water quality responsibilities for the broader Rainy-Lake of the Woods watershed. The Board was formed to assist with binational coordination of water quality efforts for the entire transboundary watershed and to ensure compliance with the Commission’s Order on the regulation of water levels on Rainy Lake and the Namakan Reservoir.
 

About the Board

Roles and responsibilities in the basin
