Minnesota faces flood risk from the Mississippi, Minnesota, Red, and Blue Earth rivers, as well as overland flooding and spring snowmelt across the state's lake-dotted landscape. The 2010 and 2011 floods along the Minnesota River caused record water levels and significant damage in communities like Le Sueur, Henderson, and St. Peter. Grand Forks along the Red River experienced one of the worst floods in Midwest history in 1997 when the Red River crested at 54.35 feet, over 22 feet above flood stage, inundating much of the city and causing $3.5 billion in damage. The Red River Valley remains one of the most flood-prone regions in the nation due to its flat terrain, northward flow, and spring snowmelt patterns. Moorhead, East Grand Forks, and other Red River communities have invested in extensive flood protection. The Twin Cities face flood risk from the Mississippi River with the 1965 and 2001 floods causing significant damage. The state has over 800 NFIP-participating communities and has been a leader in floodplain mapping through the Minnesota Department of Natural Resources. Minnesota's cold climate creates unique spring flood dynamics as accumulated winter snowpack melts rapidly.

Frequently Asked Questions — Minnesota
How bad was the 1997 Grand Forks flood?
The Red River crested at 54.35 feet, over 22 feet above flood stage. Most of Grand Forks was inundated forcing the evacuation of 50,000 people. Damages exceeded $3.5 billion and the city invested over $400 million in flood protection afterward.
Does Minneapolis flood?
The Twin Cities face Mississippi River flood risk with major floods in 1965 and 2001. The metro area has extensive floodplains along the Mississippi, Minnesota, and Rum rivers and urban development has increased flash flood risk.
When is flood season in Minnesota?
Spring snowmelt from March through May is the primary flood season. The rate of melt combined with spring rainfall determines severity. The Red River Valley is particularly vulnerable because the river flows northward into still-frozen terrain.
