4 Lakes Watershed Initiative, a stakeholder group composed of local lake management
committees, concerned citizens, municipalities, and others, is developing a
watershed based plan for the following lakes (Island, Griswold, Slocum, Napa
Suwe, Bangs) and their associated tributaries (Bangs Lake Drain, Mutton Creek
and Cotton Creek). Included in the Initiative is Port Barrington, bordered by the Fox River and the Fox River Preserve.
