Restoring Dead Dog Creek reduces sediment and nutrients flowing into Lake Michigan

The Illinois Beach State Park in northeastern Illinois is one of the last relatively undeveloped stretches of Lake Michigan shoreline between Chicago and Milwaukee. In the Village of Winthrop Harbor, located just upstream of the park, there is a severely eroded ravine that is tributary to Dead Dog Creek. Stormwater runoff picks up sediment high in phosphorous, nitrogen, and other pollutants from the fertilizers, pesticides, and other chemicals used in the residential area; the sediment and pollutants flow into Dead Dog Creek, which introduces them to Lake Michigan and its surrounding wetlands. Thanks to two grants from the Great Lakes Restoration Initiative, the Lake County Stormwater Management Commission is addressing these issues. Read more here.
