Clean water is
essential to the health and beauty of Lake Michigan.
Together, the Great Lakes contain one-fifth of the world's fresh
surface water supply, and nine-tenths of the available fresh
surface water in the U.S.
Lake Michigan is the second largest Great Lake by water volume
and is the fifth largest lake in the world by surface area.
Approximately 118 miles wide and 307 miles long, Lake Michigan
contains almost 1,180 cubic miles of fresh water.
Lake Michigan provides drinking water for 11 million people, and
the large area of water supports many other beneficial uses.
Over 43 percent of all Great Lakes fishing is done in Lake
Michigan. Large freighters support a significant commercial
shipping economy, and Lake Michigan provides water for
industrial cooling and agricultural irrigation.
