Lake Michigan is one of the five Great Lakes of North America and the only one located entirely within the United States.  It is the second-largest of the Great Lakes by volume and the third-largest by surface area. Lake Michigan is shared by Wisconsin, Illinois, Indiana, and Michigan. The word “Michigan” originally referred to the lake itself, and is believed to come from the Ojibwa word mishigami meaning “great water.”
