is lake michigan salt water
Dear Robert, More than 80 percent of the population of the Chicago metropolitan area receives water from Lake Michigan, yet little thought is given to the salt content of that water. In more understandable terms, Swenson says one cubic foot of sea water, when evaporated, yields 2.2 pounds of salt. However, one cubic foot of freshwater from Lake Michigan contains only 0.01 pound of salt. The oceans are 220 times saltier than the waters of Lake Michigan.
