Watersheds of Illinois is a list of basins or catchment areas into which the State of Illinois can be divided based on the place to which water flows.. At the simplest level, in pre-settlement times, Illinois had two watersheds: the Mississippi River and Lake Michigan, with almost the entire State draining to the Mississippi, except for a small area within a few miles of the Lake.
The aquifer underlies 1,260,000 acres (510,000 hectares) of land in east-central Illinois and spans 15 counties (Panno and Korab, 2000). The Mahomet ranges from 4 to 15 miles (6 to 24 km) and 50 to 200 feet (15 to 60 m) thick, although the average thickness is 100 feet (30 m).
Water area is 2,325 square miles (6,020 km 2); Lake Michigan accounts for most of this. Charles Mound in the northwest Driftless Area is the highest point in the state at 1,235 feet (376 m) above sea level. The Mississippi River at Cairo, Illinois is the lowest point, at 279 feet (85 m). Average elevation is 600 feet (180 m) above sea level.

In 1887, the Illinois General Assembly decided to reverse the flow of the Chicago River through civil engineering by taking water from Lake Michigan and discharging it into the Mississippi River watershed, partly in response to concerns created by an extreme weather event in 1885 that threatened the city's water supply.
