Calumet Region

Calumet Region

The Calumet Region is the name given to the geographic areas drained by both the Grand Calumet River and the Little Calumet River. It is included within the Great Lakes Watershed, which eventually reaches the Atlantic Ocean. This region includes the northern parts of both Lake and Porter counties in Indiana, as well as the easternmost counties of northern Illinois. Since much of this region is on the south shore of Lake Michigan, it is sometimes referred to as the South Shore. Because it was initially cut off from the rest of the state due to natural geographic barriers like the Kankakee Marsh to the south, the Calumet Region was the last-settled portion of the Indiana. It is a sub-region of the greater Northwest Indiana region and the even larger Great Lakes region.
