The DuPage River is a 28.3-mile-long (45.5 km)tributary of the Des Plaines River in the U.S. state of Illinois.
The river begins as two individual streams. The West Branch of the DuPage River, 35.0 miles (56.3 km) long, starts in Schaumburg at Campanelli Park in Cook County and continues southward through the entire county of DuPage, including the towns of Bartlett, Wheaton, Warrenville, Winfield and Naperville (including through its riverwalk). The East Branch of the DuPage River, 25.0 miles (40.2 km) long, begins in Bloomingdale and flows southward through Glendale Heights, Glen Ellyn, Lisle, Woodridge, parts of Naperville and parts of Bolingbrook. The two branches meet at a spot between Naperville and Bolingbrook. The combined DuPage River continues southward from that point, through Plainfield & Shorewood and then west of Joliet, before finally meeting the Des Plaines River.
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.
