The History of the Chicago River

The Chicago River has a rich history as a vital transportation route, originally flowing into Lake Michigan. In the late 1800s, rapid urban growth and pollution led engineers to reverse its flow, directing sewage away from drinking water and improving sanitation. This engineering feat, known as the Chicago River Reversal, transformed the river into a conduit for industry and commerce. Today, it’s also a recreational and aesthetic feature, with initiatives focused on ecological restoration and sustainable water management, balancing urban development with environmental health. The river's history reflects Chicago’s ingenuity and ongoing efforts to harmonize city growth with natural ecosystems.
