Four of the Five Great Lakes — Superior, Michigan, Huron, and Erie — define Michigan’s boundaries and taken together create a shoreline over 3,200 miles long.  That’s more shore line than the entire eastern coast of North America. 


  • Because of the Great Lakes, Michigan climate is classified as semi-maritime, even though the state lies more than 600 miles from the nearest ocean.


  • Michigan  is surrounded by water; 40,000 square miles of Great Lakes; laced with 37,000 miles of rivers and streams and more than 11,000 inland lakes, along with countless bogs, fens and marshes.  These inland waters contain 150 named waterfalls and more than 3,000 islands, some of them large enough to boast lakes of their own.


  • Altogether the Great Lakes hold one-fifth of the world's fresh surface water.


  • Some 83 boating harbors line the 3,200 miles of shoreline. Safe harbors are never more than 15 shoreline miles away.


  • You can stand anywhere in the state and you are always within 85 miles of a Great Lake and six miles of a lake or stream.


  • Lake Superior is the largest body of fresh water in the world at 31,800 square miles of fresh water.


  • Lake Michigan is the world’s sixth largest lake. The 307 mile long lake is the only Great Lake entirely within the boundaries of the United States.


  • Along the southern edge of Saginaw Bay north to Lake Superior hundreds of thousands of 300+ year old white pines, towering some 200 feet and measuring five feet in diameter started the logging trade for the first settlers, within 50 years it was all gone.


  • Detroit is the only major American City in which you can stand downtown and look south at Canada. 


  • Another great trivia fact is that Detroit is the only major U.S. city to have been occupied by a foreign power.  It was taken over by the British during the War of 1812.
