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.
  • This brought widespread areal flooding and major river flooding to northern Illinois into northern Indiana. Rivers reached record levels on parts of the Kankakee and Iroquois River basins (see graphic to the right).
