Summary of the Major River Flooding Experienced and the Rain Behind It

Overview

Fast Facts/Records Set:

Multiple episodes of heavy rain fell over the region during February 19-20, with the heaviest amounts along and southeast of the Illinois River.
- The heaviest rainfall was over east central Illinois into northwest Indiana, where four to six and a half inches of rain fell, the highest being 6.50" near Wheatfield, IN.
