The Dunes Creek Watershed Management Project
Dunes Creek begins west of State Road 49 and enters Lake Michigan at the Indiana Dunes State Park’s pubic swimming beach. Its 7,407 acre watershed encompasses all of the State Park, Cowles Bog, and large portions the Indiana Dunes National Lakeshore. Before the development of the residential areas, industry, and farmland, Dunes Creek, fed by the Great Marsh, meandered slowly northward through woodlands and interdunal areas. Many sections of the Creek have been straightened and the surrounding wetlands ditched and drained. Dunes Creek has been listed on the Indiana Department of Environmental Management (IDEM’s) Impaired Waters List for E. coli and impaired biotic communities since 1998.
