The Straits of Mackinac hydraulically link Lakes Michigan and Huron (Figure 1), and are wide and deep enough (average depth 20 m) to permit the same average water level in both water bodies, technically making them two lobes of a single large lake. The combined Michigan–Huron system forms the largest lake in the world by surface area and the fourth largest by volume, containing nearly 8% of the world's surface freshwater. The Straits of Mackinac serve as a hub for recreation, tourism, commercial shipping, as well as commercial, sport and subsistence fishing (several tribes retain fishing rights in these 1836 treaty-ceded waters).
