Geography of Michigan - Lakes and Rivers

Lakes and Rivers

Numerous lakes and marshes mark both peninsulas, and the coast is much indented. Keweenaw Bay, Whitefish Bay, and the Big and Little Bays De Noc are the principal indentations on the Upper Peninsula. The Grand and Little Traverse, Thunder, and Saginaw bays indent the Lower Peninsula. After Alaska, Michigan has the longest shoreline of any state—3,288 miles (5,326 km). An additional 1,056 miles (1,699 km) can be added if islands are included. This roughly equals the length of the Atlantic Coast from Maine to Florida.

The state has numerous large islands, the principal ones being the Manitou, Beaver, and Fox groups in Lake Michigan; Isle Royale and Grande Isle in Lake Superior; Drummond, Marquette, Bois Blanc, and Mackinac islands in Lake Huron; and Neebish and Sugar islands in St. Mary's River. Michigan has about 150 lighthouses, the most of any U.S. state. The first lighthouses in Michigan were built between 1818 and 1822. They were built to project light at night and to serve as a landmark during the day to safely guide the passenger ships and freighters traveling the Great Lakes. See Lighthouses in the United States.

The state's rivers are small, short and shallow, and few are navigable. The principal ones include the Au Sable, Thunder Bay, Cheboygan, and Saginaw, all of which flow into Lake Huron; the Ontonagon, and Tahquamenon, which flow into Lake Superior; and the St. Joseph, Kalamazoo, Grand, Muskegon, Manistee, and Escanaba, which flow into Lake Michigan. The state has 11,037 inland lakes and 38,575 square miles (62,067 km²) of Great Lakes waters and rivers in addition to 1,305 square miles (3,380 km2) of inland water. No point in Michigan is more than six miles (10 km) from an inland lake or more than 85 miles (137 km) from one of the Great Lakes.

Famous quotes containing the words lakes and, lakes and/or rivers:

    The Indian navigator naturally distinguishes by a name those parts of a stream where he has encountered quick water and forks, and again, the lakes and smooth water where he can rest his weary arms, since those are the most interesting and more arable parts to him.
    Henry David Thoreau (1817–1862)

    Though the words Canada East on the map stretch over many rivers and lakes and unexplored wildernesses, the actual Canada, which might be the colored portion of the map, is but a little clearing on the banks of the river, which one of those syllables would more than cover.
    Henry David Thoreau (1817–1862)

    As for evildoers, for them awaits a painful chastisement;
    but for those who believe, and do deeds
    of righteousness, they shall be admitted
    to gardens underneath which rivers flow,
    therein dwelling forever,
    by the leave of their Lord, their greeting
    therein: “Peace!”
    Qur’An. Abraham 14:28 (ed. Arthur J. Arberry, 1955)
