Which Great Lake is the only one entirely within the United States?

Lake Michigan is the only Great Lake that is entirely within the United States, making it unique among its counterparts. It does not share its shoreline with Canada, unlike the other Great Lakes, which are bordered by both the United States and Canada. This exclusivity is an important geographical distinction.

Lake Erie, for instance, is situated on the border between the United States and Canada, with cities like Cleveland in Ohio and Windsor in Ontario lining its shores. Lake Superior, while primarily located in the U.S. and containing the largest volume of fresh water, also has a significant portion of its shoreline in Canada. Similarly, Lake Huron has both U.S. and Canadian shores, with islands such as Manitoulin Island in Ontario lying within its waters.

This unique geographical positioning of Lake Michigan contributes to its identity and relevance in various ecological, cultural, and recreational contexts in the United States.
