The Illinois River, a major tributary approximately 273 miles (439 km) long in the state of Illinois, United States, is the primary feeder of the Mississippi River. The river begins at the confluence of the Des Plaines and Kankakee Rivers in Chicago and flows southwest through Illinois before eventually joining the Mississippi River. Its drainage basin includes central Illinois, southeastern Wisconsin, northwestern Indiana, and a very small southwestern corner of Michigan.
Geography aside, the history of the Illinois River dates back to the days of early Native Americans and French traders. As an important waterway connecting the Great Lakes region to the Mississippi River, the river played a key role in French colonial settlement in the 17th and 18th centuries.
Rivers, in particular, offer a thriving source of livelihood for early inhabitants due to their potential for fertile soils, grasslands and forests.
As early as 1675, Jesuit missionary Jacques Market established the first European settlement here, marking the Illinois River's importance as a trade route. In 1680, French explorer La Salle founded Fort St. Louis here to support the fur trade. These historical events highlight the river's central role in early trade, making it a bridge between civilizations.
The river's role in freight transportation was further expanded with the construction of the Illinois and Michigan Canal and the Hennepin Canal in the 19th century. These canals established the Illinois River as a waterway connecting the Great Lakes and the Mississippi, spurring industrial development and population expansion in the region.
In the 19th and early 20th centuries, residents of river towns developed a unique cultural and economic dependency on the resources of the Illinois River, from fishing to tourism.
However, this once prosperous river also faces ecological and economic challenges. Overfishing and water pollution are escalating problems, especially with invasive Asian catfish, which are out-competing native fish for their habitat.
Although commercial fisheries have declined significantly, the Illinois River remains an important recreational fishing destination and plays a significant role in today's waterway system. To protect the river, the City of Peoria plans to reduce sewage overflows into the river, a long-term approach that complies with U.S. EPA and Illinois EPA requirements.
"No matter how many ups and downs the river has experienced, the Illinois River remains the foundation of local culture and economic activity."
The history and current state of the Illinois River show how the river has played a vital role in American history. As we face environmental and ecological challenges, valuing and protecting this river is equally critical to understanding our past and shaping our future. This is not only a responsibility to natural resources, but also a responsibility to history.
