Which Great Lake is entirely bordered by the state of Michigan?

Lake Michigan is unique among the Great Lakes because it is the only one that is entirely bordered by a single state, which is Michigan. This is significant as it means that there are no other states or countries along its shoreline; it is exclusively a Michigan lake.

The lake's geography supports various recreational activities and has a variety of beaches and coastal attractions within the state. In contrast, the other Great Lakes are bordered by multiple states or even countries. For instance, Lake Huron is shared with Canada and other states, Lake Erie is shared with both Canada and several U.S. states, and Lake Ontario is primarily bordered by Canada, including the province of Ontario, along with New York in the U.S. This unique status of Lake Michigan makes it an important geographical and cultural element of Michigan.
