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 will likely break the current all-time records. 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 into June.

As of May 25, many of the major tributaries upstream (like Basswood River, Vermilion River, Kawishiwi River) have crested and are beginning to drop. However, this will only slow the rise of Namakan/Kabetogama and Rainy Lake - continued rises are still anticipated in the coming days:

Namakan Lake and Kabetogama Lake are currently at 1122.0 ft (341.99 m), which is 17.7 inches (45 cm) above the 2014 peak level. A rise of 5 to 7 inches (12-19 cm) is expected between May 25 and June 1 with continued rises into mid June possible. At this rate, Namakan Lake will reach the all-time record high level  of 1122.8 ft  (342.24 m) set in 1916.

Rainy Lake is currently at 1111.7 ft (338.85 m), which is 4 inches (11 cm) above the 2014 peak. A rise of 11 to 13 inches (27-33 cm) is expected between May 25 and June 1, with continued through at least mid June. At this rate, Rainy Lake is expected to break the all-time record high level of 1112.95 ft (339.23 m) set in 1950.
