The East Branch of the Little Calumet River or the LCEB is found at the South end of Lake Michigan about 50 miles from Chicago. It is found inside the state of Indiana. The map below was in Google MyMaps. The purple dot shows the location of the river in the United States map.

The river starts at the Round Lake in LaPorte County. It ends at the merge of the West Branch of the Little Calumet River at the Burns waterway in Portage (Whitesell, 2015). This then flows into Lake Michigan between the Portage Lakefront, which is part of the Indiana Dunes National Park, and the Midwest Steel Mill. The map below flows the flow of the river from the start to the ending into Lake Michigan.

The LCEB comprises 47,293 acres of land that encompasses the towns of Chesterton, Porter, Portage and Burns Harbor and the city of Portage (Whitesell, 2015). The map below shows my rough drawing of the watershed.

The map below shows the subwatersheds that comprise the larger water shed. The three subwatersheds are the Coffee Creek, Kempers Ditch and Reynolds Creek (Whitesell, 2015).

Watersheds are designated by their hydrologic unit codes (HUCs). The largest watersheds have 8 digits, medium ones (located inside the larger 8 digit ones) have 10 digits and the smaller ones (located inside the medium 10 digits ones) have 12 digits. The table below shows the HUCs for the Calumet- Galien watershed and follows down to the smallest subwatersheds (Whitesell, 2015).
