Named for the Huron Indians who lived on its shores, Lake Huron is one of the
Great Lakes. It lies on the international boundary between Canada and the United States, separating
Michigan and
Ontario. Its waters are at the same level as
Lake Michigan and are only slightly lower than
Lake Superior. The two most important islands in Lake Huron are Mackinac Island in Michigan and Manitoulin Island in Ontario. Lake Huron drains into the St Clair River at its southernmost point, which is between
Port Huron in Michigan and
Sarnia in Ontario.
