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 km2).[6] The Illinois River begins with the confluence of the Des Plaines and Kankakee rivers in the Chicago metropolitan area, and it generally flows to the southwest across Illinois, until it empties into the Mississippi near Grafton, Illinois. Its drainage basin extends into southeastern Wisconsin, northwestern Indiana, and a very small area of southwestern Michigan in addition to central Illinois. Along its shores are several river ports, including Peoria, Illinois. Historic and recreation areas on the river include Starved Rock, and the internationally important wetlands of the Emiquon Complex and Dixon Waterfowl Refuge.
The river was important among Native Americans and early French traders as the principal water route connecting the Great Lakes with the Mississippi. The French colonial settlements along these rivers formed the heart of the area known as the Illinois Country in the 17th and 18th centuries. After the construction of the Illinois and Michigan Canal and the Hennepin Canal in the 19th century, the role of the river as link between Lake Michigan and the Mississippi was extended into the era of modern industrial shipping. The Illinois now forms the basis for the Illinois Waterway, extending the river's capabilities for navigation and commercial shipping.
Hydrography
The Illinois River is formed by the confluence of the Kankakee River and the Des Plaines River in eastern Grundy County, approximately 10 miles (16 km) southwest of Joliet. Its other major tributaries include the Fox, Vermilion, Macoupin, Mackinaw, Spoon, Sangamon, and La Moine.[7] This river flows west across northern Illinois, passing Morris and Ottawa, where it is joined by the Mazon River and Fox River respectively. At LaSalle, the Illinois River is joined by the Vermilion River, and then it flows west past Peru and Spring Valley. In southeastern Bureau County it turns south at an area known as the "Great Bend", flowing southwest across western Illinois, past Lacon, Henry and downtown Peoria, the chief city on the river.
South of Peoria, the Illinois River goes by
Near the confluence of the Illinois with the La Moine River, it turns south, flowing roughly parallel to the Mississippi across western Illinois. Macoupin Creek joins the Illinois on the border between Greene and Jersey counties, approximately 15 miles (24 km) upstream from the confluence with the Mississippi River.
For the last 20 miles (32 km) of its course, the Illinois is separated from the Mississippi River by only about five miles (8 km), by a peninsula of land that makes up Calhoun County. The Illinois joins the Mississippi near Grafton, approximately 25 miles (40 km) northwest of downtown St. Louis and about 20 miles (32 km) upstream from the confluence of the Missouri River and the Mississippi.

Because of the manner of its formation, the Illinois River runs through a deep canyon with many rock formations. It has an "underutilized channel", one far larger than would be needed to contain any conceivable flow of the modern river.
History
The Illinois River valley has long been an important transportation route for civilizations. The portages between the
In 1680, René-Robert Cavelier, Sieur de La Salle built the first fort in Illinois, Ft. St. Louis, at Starved Rock to facilitate the fur trade and defend the Illinois against the Iroquois. Later the fort was relocated to the present site of Creve Coeur, near Peoria. The French retained a presence in the area, with small trading posts.[10]
Prior to the construction of the Illinois & Michigan Canal, completed in 1845, Peoria was the only large settlement on the River. The river's trade flowed down to be dominated by St. Louis. After the I&M Canal saw a string of cities, such as LaSalle, Peru, and Ottawa grow along the river, extending Chicago's influence into the Mississippi Valley. During the nineteenth and early twentieth centuries, the residents of the river towns were deeply involved in harvesting the river's fish, waterfowl, mussels, and ice. They were economically and culturally dependent on the river, building up industries such as tourism related to duck hunting and sport fishing, commercial fishing, musseling for the button factories, and ice cutting for early attempts at refrigeration for domestic and commercial use.[11]
With the construction of the Chicago Sanitary and Ship Canal, Chicago's sewage was pushed down the river rather than into Lake Michigan.[11]
As the canal declined by the early 1900s, it was eventually replaced by the Illinois Waterway in 1933, still in use today.[12]
Interpretation
The Peoria Riverfront Museum contains a gallery, "Illinois River Encounter," that offers an interpretation of the river through an aquarium tank, and displays of the river's geology, ecology, social history, engineering, and commercial use.[13] The Starved Rock Lock and Dam Visitor Center features exhibits on the Illinois River with a viewing area of the working lock in a site frequented by bald eagles.[14]
Modern use
From 1905 to 1915, more freshwater fish were harvested from the Illinois River than from any other river in the United States except for the Columbia River. The Illinois River was once a major source of mussels for the shell button industry. Overfishing, habitat loss from heavy siltation, and water pollution have eliminated most commercial fishing except for a small mussel harvest to provide shells to seed pearl oysters overseas. It is commercially fished downstream of the Rt. 89 bridge at Spring Valley. However, an infestation of invasive Asian Carp has crowded out many game fish in the river.[15] The Illinois River is still an important sports fishing waterway with a good sauger fishery.

The John Hartford song "Long Hot Summer Day" is written from the perspective of a barge worker on the Illinois River.[18] It references the Illinois towns of Pekin, Beardstown, and Alton.
