Which Great Lake lies entirely within the boundaries of the United States?

Lake Michigan is unique among the Great Lakes because it is the only one that lies entirely within the boundaries of the United States. It does not share its shoreline with Canada, giving it a distinct status compared to the other Great Lakes, which either border Canada or have portions of their shoreline in Canada. Lake Huron, for example, shares a significant portion of its northern shoreline with Canada, while both Lake Erie and Lake Superior touch Canadian land as well. This makes Lake Michigan stand out not only in terms of geography but also in terms of management and recreation, being completely under U.S. jurisdiction. The state's cities, recreational activities, and ecological zones are directly influenced by this unique geographical situation.
