A levee is about to break in Marseilles, a town about 75 miles southwest of Chicago situated along the swollen Illinois River.
Over 100 homes are flooded and police went door-to-door telling people to evacuate and get to higher grounds.
Marseilles Fire Chief Mick Garrison said 1,200 residents had to evacuate, and all the residents of a nursing home in Marseilles were also evacuated for their safety.
The surging waters of the Illinois River also caused about a half dozen barges to break loose and slam into a nearby dam.
At last report, three of the barges were still afloat. However, two others were half-way submerged while another barge is completely under water.
