Rainy River Basin Summary Page
High water levels are occurring across the Rainy River Basin in far northern Minnesota and adjacent parts of Ontario. This is a historic flood that has already exceeded the records set in the 2014 flooding, and could break all-time records for lake levels on Namakan/Kabetogama Lake and Rainy Lake. It will take a long time for these levels to decrease once they peak (crest), and those experiencing flooding should be prepared for weeks of high water levels through June.
