East Central Iowa and Northwest Illinois Flooding - June 4, 2002

 

Heavy rains which fell during the first week of June caused significant flash flooding rivaling that caused by storms during the summer of 1993.  Flash flooding occurred at Indian Creek in Cedar Rapids, Iowa and across the NWS Quad Cities, IA/IL county warning area (CWA). 

The counties hit hardest were Whiteside, Carroll, Bureau, Jo Daviess and Stephenson where storm total rainfall amounts were as high as 6 to 10 inches, with Delaware and Dubuque counties in Iowa recieving between 8 and 11 inches.  This heavy rain resulted in widespread and significant flash flooding and river flooding.  The Rock River reached record flood levels near Joslin, while at Moline the second highest crest was recorded. 

Flash flooding caused significant property damage to homes and businesses.  Damage was also significant to farm land and public property including roads, parks and utilities.  Public property damage in Northwest and West Central Illinois due to the flooding was around $3 million dollars.  This equaled or exceeded the 1 in 100 year event for a 48hr period.  Rainfall rates of over 2 inches per hour were recorded.  Seventeen eastern Iowa counties were declared federal disaster areas with 7.2 million dollars on property damage.
