Fox River Illinois Basin

The Southeast Fox River Basin is located in portions of seven counties, contains (entirely or portions of) 10 cities, 22 villages, 42 towns, and is home to about 500,000 people. The basin is divided into seven watersheds. Three of the watersheds (Upper, Middle and Lower Fox River) contain the Fox River from start to finish and collectively occupy nearly half the basin area (513 square miles). The other watersheds are named after the major rivers they contain. Collectively the seven watersheds contain about 750 miles of perennial streams, over 600 miles of intermittent streams, 78 named lakes and impoundments and many unnamed lakes and ponds. Wetlands encompass nearly 78,000 acres, or 11 percent of the basin land area.
