Widespread flooding continued from April into May across southern Illinois. Following excessive rain in April, a final dose of heavy rain came between April 30 and May 2. Numerous rounds of showers and thunderstorms produced additional average rainfall amounts of 4 to 6 inches. Between 9 and 22 inches of rain fell across the region between April 22 and May 3. Most creeks and streams flooded for an extended period of time. Some of the flooding was major. The Saline River threatened some homes and businesses in parts of Saline County around Muddy, Eldorado, and Harrisburg. In Carbondale, more than 30 mobile homes were flooded at a trailer park that was inundated by Crab Orchard Creek. 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. At the peak of the flooding, 41 county and state roads were closed in Williamson County alone. A number of bridges were underwater. About 50,000 acres of farmland was flooded in Hamilton County. The flood damage from creeks and small rivers was considered to be lower than the historic March, 2008 flood in most areas. including Harrisburg. Flood gates installed around Harrisburg prevented a repeat of the massive 2008 flood, but Illinois Route 34 was closed by the flood gate. Businesses in Harrisburg sandbagged in anticipation of possible flooding, but few if any businesses were flooded.
