Flood — McLean, IL

May 1, 2019

Flood Cause
Heavy Rain

Heavy rainfall on April 30th led to areal flooding of many central Illinois communities from Morgan County northeastward to DeWitt County on May 1st. Overflowing creeks and water flowing out of farm fields caused the closure of numerous roads. IL-78 just south of the Jacksonville Airport in Morgan County was closed for a time, as were several county roads in Menard and Logan counties.
