The Kankakee River is a 133-mile river that flows through Indiana and Illinois. It was historically used for transportation and provided a source of water for agriculture. The river has a diverse ecosystem, with over 200 species of fish, including several endangered species. The river's hydrology has been altered by the construction of several reservoirs and dams, including the Kankakee River State Park Dam and the Wilmington Dam. These dams have been built for flood control, hydroelectric power, and recreation. The river is a popular destination for boating, fishing, and camping. The river and its surrounding wetlands also provide important habitat for waterfowl and other wildlife. Agriculturally, the river is used as a source of irrigation for corn, soybeans, and other crops.
