| | Chicago River |
 | | The river is also a part of a system that includes the North Branch, South Branch, and Main Stem of the Chicago River, as well as 52 miles of constructed waterways: the North Shore Channel, the Sanitary and Ship Canal, and the Calumet Sag Channel. |
 | | Before Euro-American settlement and the development of Chicago and its suburbs, the North Branch of the Chicago River was fed by three small streams with headwaters near present-day Deerfield, Glencoe, and Winnetka. |
 | | Locks located near Lake Michigan and at Lockport diverted the flow of the North Branch, South Branch, and Main Stem into the canal and to the Des Plaines River. |
