Title: Illinois River
Content:  The Illinois River is a principal tributary of the Mississippi River and is approximately 273 mi long. Located in the U.S. state of Illinois, the river drains a large section of central Illinois, with a drainage basin of 28756.6 sqmi. The drainage basin extends into Wisconsin, Indiana, and a very small area of southwestern Michigan. 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.
Title: Geography of Illinois
Content:  Illinois is mainly bounded by rivers, and the Illinois River bisects the state. A few rivers, including the Fox and Rock Rivers enter the State from Wisconsin. The Iroquois and Kankakee arise in Indiana, but lose their identity before reaching the Mississippi. The North Fork of the Vermilion River arises in Indiana, but joins the Vermilion, which exits the state before joining the Wabash River in Indiana. Other rivers include the Ohio River, the Kaskaskia River, the Sangamon River and the Chicago River. The Cashe River area in southern Illinois forms the basis for a Ramsar Convention Wetland of International Importance.
Title: Illinois River (Colorado)
Content:  Illinois River is a tributary of the Michigan River, approximately 71 mi long, in Jackson County in north central Colorado. It drains part of the North Park basin south of Walden. The Illinois River starts in the Never Summer Mountains near the continental divide, just south of Farview Mountain. It descends northward through a winding gorge, emerging into North Park at approximately 8000 ft above sea level. It flows northward through the valley as a winding stream, past Rand. It passes under State Highway 14 just southeast of Walden and joins the Michigan from the north just north of Walden. A portion of the valley of the river south of Walden is located within the Arapaho National Wildlife Refuge.
Title: Illinois River (Oregon)
Content:  The Illinois River is a tributary, about 56 mi long, of the Rogue River in the U.S. state of Oregon. It drains part of the Klamath Mountains in northern California and southwestern Oregon. The river's main stem begins at the confluence of its east and west forks near Cave Junction in southern Josephine County. Its drainage basin includes Sucker Creek, which rises in the Red Buttes Wilderness, near Whiskey Peak on the California state line. The main stem flows generally northwest in a winding course past Kerby and through the Siskiyou National Forest and Kalmiopsis Wilderness. It joins the Rogue River from the south at Agness on the Curry&ndash;Josephine county line, 27 mi from the Pacific Ocean. The river's lower 50.4 mi, from where it enters the Rogue River–Siskiyou National Forest downstream from Kerby to its confluence with the Rogue River, were designated Wild and Scenic in 1984. Of this, 28.7 mi is protected as wild, 17.9 mi as scenic, and 3.8 mi as recreational.
Title: Illinois River
Content:  The Illinois River is formed by the confluence of the Kankakee River and the Des Plaines River in eastern Grundy County, approximately 10 mi southwest of Joliet. This river flows west across northern Illinois, passing Morris and Ottawa, where it is joined by the Mazon River and Fox River. 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. 
Title: Bridges in Peoria, Illinois
Content:  Peoria and East Peoria, Illinois are separated by the Illinois River, a 240 mi long body of water that reaches up to a mile across in places along Peoria Lake. The Illinois River is one of six rivers that are included in the Lower Illinois River Basin which extends between Ottawa, Illinois and the Mississippi River at Grafton, Illinois. Three of the six rivers in the Lower Illinois River Basin (Spoon River, Illinois River, and Mackinaw River) are in central Illinois. Their combined length is 534 nmi. Of these waterways the Illinois is thought to be the only river large enough to support barge traffic. In 
Title: Illinois River (Oklahoma)
Content:  The Illinois River is a 145 mi tributary of the Arkansas River in the U.S. states of Arkansas and Oklahoma. The Osage Indians named it Ne-eng-wah-kon-dah, which translates as "Medicine Stone River." The state of Oklahoma has designated its portion as a Scenic River. The Illinois River is a significant location in the 1961 Wilson Rawls novel, Where the Red Fern Grows.

Title: Mississippi River System
Content:  The Illinois River is a principal tributary of the Mississippi River. The river runs approximately 273 miles (439 km) long, in the U.S. state of Illinois. This river was important among Native Americans and early French traders as the principal water route connecting the Great Lakes with the Mississippi. The Illinois River meets the Mississippi at Pere Marquette State Park, which is near Grafton. The confluence of the rivers offers vistas that seem endless. The Illinois River is relatively shallow, just like the Mississippi. In addition, the Illinois River is a "managed" river, just as the Mississippi River is. In 1848, the Illinois and Michigan Canal opened to connect Lake Michigan with the Mississippi River through the Illinois River to promote commerce.
Title: Vermilion River (Illinois River tributary)
Content:  The Vermilion River is a 74.8 mi tributary of the Illinois River in the state of Illinois, United States. The river flows north, in contrast to a second Vermilion River in Illinois, which flows south to the Wabash River. The Illinois and Wabash rivers each have a tributary named the Little Vermilion River as well. The north-flowing Vermilion River and the south-flowing Middle Fork Vermilion River run on what is close to a straight line between Oglesby and Danville. In presettlement times, the two rivers drained an upland marsh near Roberts. It is possible that early settlers regarded these as a single river that flowed in two directions. It is also possible that, in early settlement times, these rivers formed a canoe
