Socio-Political

Economic Value Half of Canadian manufacturing and one-fifth of U.S. manufacturing are based on the Great Lakes freshwater coasts. The binational region accounts for about 60 percent of steel production in North America. Pulp and paper plants, high tech and chemical industries, and other light manufacturing use the region's lakes for water and transportation of goods. (GLIN, 2003)
Major Cities Chicago, Illinois U.S.
Milwaukee, Wisconsin U.S.
