Detroit River AOC Boundary Map
Physical boundaries of the Detroit River AOC extend from the flashing navigation light near Peche Island to a point in the center of the Detroit River approximately in line with the mouth of Michigan’s Huron River. The Detroit River, a 32-mile (51 km) long channel linking Lake St. Clair and the upper Great Lakes to Lake Erie, is part of the international boundary between the United States and Canada. It can be misleading to think of the Detroit River as a typical river with a fan-shaped watershed. Instead, it is part of a strait that connects the Upper Great Lakes to the Lower Great Lakes. Lake Huron water makes up 95% of the flow of the Detroit River via the St. Clair River and Lake St. Clair (MDNR 1991).
