Lake HuronLake Huron is one of the five Great Lakes of eastern North America, and separates Michigan from Ontario. Georgian Bay, the easternmost part of Lake Huron, is entirely within Canada.
Lake Huron is separated from Lake Michigan, which lies at the same level, by a narrow channel; Lake Superior is slightly higher and drains into Lake Huron at Sault Ste. Marie. The water then flows south to the St. Clair River, at Port Huron, Michigan and Sarnia, Ontario.
The surface of Lake Huron is 579 feet above sea level, and the lake's maximum depth is 750 feet. It covers an area of about 23000 square miles. It contains 3,538 cubic km of water. Like the other Great Lakes, it is the remnant of the larger Glacial Lake Agassiz, formed by melting ice as the continental glaciers retreated.
