Widespread heavy rainfall from 8 to 14 inches occurred during the last week of April. At the Carbondale airport, a rainfall total of 11.01 inches was measured from April 22-30. This excessive rainfall caused most creeks and streams to flood for an extended period of time. Some of the flooding was major. A disaster proclamation was issued by the governor of Illinois due to the damage from flooding and severe storms. The National Guard was deployed to assist with sandbagging and other operations. Numerous roads were flooded and closed across southern Illinois, including some major state roads. A number of bridges were underwater, including ten in Union County alone. Just a few of the small rivers that caused damaging floods included the Little Cache River at Vienna and the Saline River at Harrisburg. In each case, the flood damage was relatively low compared to the March, 2008 flood. A few water rescues were conducted, including a residence evacuated by boat in the Harrisburg area.
