Diagram depicting the sources and cycles of acid rain precipitation. Freshwater acidification occurs when acidic inputs enter a body of fresh water through the weathering of rocks, invasion of acidifying gas (e.g. carbon dioxide), or by the reduction of acid anions, like sulfate and nitrate within a lake, pond, or reservoir.

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 effects of acid rain are mostly seen in aquatic ecosystems. As the rain flows through the soil, the acidic water can drain away aluminum from the soil and them flow into streams and lakes. As more acid is released into the environment, more aluminum is also released. There are some plants and animals that are able to tolerate acid rain and ...

The Great Lakes Basin consists of the Great Lakes and the surrounding lands of the states of Illinois, Indiana, Michigan, Minnesota, New York, Ohio, Pennsylvania, and Wisconsin in the United States, and the province of Ontario in Canada, whose direct surface runoff and watersheds form a large drainage basin that feeds into the lakes.
An ice jam along the Sangamon River in Menard County causes water levels to rise Friday, January 26, 2024. Flooding has been reported in low-lying agricultural areas.
The Illinois River (Miami-Illinois: Inoka Siipiiwi [4]) is a principal tributary of the Mississippi River at approximately 273 miles (439 km) in length. Located in the U.S. state of Illinois , [ 5 ] the river has a drainage basin of 28,756.6 square miles (74,479 km 2 ). [ 6 ]
