What does the snow to the north mean for the Mississippi River in our region?

The Mississippi River crested at moderate to major flood levels from Camanche downstream to Gregory Landing earlier this week. This magnitude of flooding was in response to widespread heavy rains that fell last week across eastern Iowa, northeastern Missouri, and much of Illinois.

Now that the Mississippi River levels has begun to slowly recede, some may be looking to the north and wondering... What does the upcoming snow melt mean for the Mississippi River in our region?

  • A substantial snow pack remains from north of the Twin Cities across northern Minnesota, and across far northern Wisconsin. Since this area of snow pack is concentrated well to our north, it will take on the order of a couple weeks from the time the snow melts to when its runoff would reach this portion of the Mississippi River.  
  • A significant flood risk due to the snowmelt alone this far south is not anticipated. Any additional spring season heavy rains in our region would pose a greater flood risk in the coming weeks.
