Flooding
Like many local bodies of water, both branches of the DuPage River seriously overflowed after the "Flood of 1996", when approximately 17 inches (430 mm) of rain fell on the area within a 24-hour period, on July 18–19 of that year. Other flooding was also very common, along Washington Street in Naperville and Illinois Route 53 in Glen Ellyn, because those roads are close to their respective branches of the river. The City of Naperville has torn down many of the affected homes and businesses, in the former case, and DuPage County, with U.S. Department of Transportation funding, tore down many of the affected homes in the latter case. A new dam that was built in 2009 has been a tremendous help in managing the river's level.
