Lake Michigan is the third largest Great Lake by surface area and the sixth largest freshwater lake in the world. Since Lake Michigan and Lake Huron are connected by the Straits of Mackinac, they are considered one lake hydrologically. If they were considered a single lake, its surface area would cover 45,000 square miles and would replace Lake Superior as the largest freshwater lake.
