The Grand Calumet River is a 13.0-mile-long (20.9 km) [3] river that flows primarily into Lake Michigan. Originating in Miller Beach in Gary , it flows through the cities of Gary, East Chicago and Hammond , as well as Calumet City and Burnham on the Illinois side.
Historically, the Little Calumet River and the Grand Calumet River were one, the former flowing west from Indiana into Illinois, then turning back east to its mouth at Lake Michigan at Marquette Park in Gary. [1] Now the system is part of the Chicago Area Waterway System and through the use of locks flows away from Lake Michigan to the Cal-Sag ...
The location of the new lock and dam 7 miles (11 km) upstream from the old controlling works at Blue Island was chosen to improve the ability to control backflow events into the lake during heavy storms from the polluting industries along the Grand Calumet River and Little Calumet River and the outfall of the Calumet Water Reclamation Plant.

The Chicago Area Waterway System (CAWS) is a complex of natural and artificial waterways extending through much of the Chicago metropolitan area, covering approximately 87 miles altogether. It straddles the Chicago Portage and is the sole navigable inland link between the Great Lakes and the Mississippi River and makes up the northern end of ...
The Cal Sag Channel is a part of the highly polluted Calumet River system. Today, sediments on the river bottom are "among the most contaminated and toxic that have ever been reported." Only sludge worms inhabit the Indiana Harbor and Ship Canal, indicating that severe pollution exists.
The related Calumet-Saganashkee Channel does the same for the Calumet River a short distance to the south, joining the Chicago canal about halfway along its route to the Des Plaines. The two provide the only navigation for ships between the Great Lakes Waterway and the Mississippi River system. The canal was in part built as a sewage treatment ...
As a groundwater aquifer, the Calumet Aquifer provides water to local surface waterways, including the Grand Calumet River and Little Calumet River. [2] The contributions can go in both directions: when the Little Calumet is in flood stage, it rises above the aquifer level and water from the river enters the aquifer. [7]
