The Chicago River is a system of rivers and canals with a combined length of 156 miles that runs through the city of Chicago, including its center. The river is one of the reasons for Chicago's geographic importance: the related Chicago Portage is a link between the Great Lakes and the Mississippi River Basin, and ultimately the Gulf of Mexico.
