Is located in St. Clair County near the Detroit metropolitan area. The 39-mile long St. Clair River has recreational harbors in St. Clair and Marine City before the river divides into several branches at its mouth, creating the island strewn St. Clair Flats.

Harsens Island, the largest of the islands on the American side, was once a resort for the wealthy who arrived on steamers from Detroit. Today, Harsens Island and the St. Clair Flats area comprises one of the largest inland fresh water deltas in the world.
