Lake Carriers’ Association represents 17 American companies that operate 55 U.S.-flag vessels on the Great Lakes and carry the raw materials that drive the nation’s economy: iron ore and fluxstone for the steel industry, limestone and cement for the construction industry, coal for power generation.... Collectively, these vessels can transport more than 115 million tons of cargo a year when high water offsets lack of adequate dredging. More information is available at www.lcaships.com.
