Year-to-date the Lakes limestone trade stands at 9.8 million tons, a decrease of 1 percent compared to a year ago.  Loadings out of Michigan and Ohio quarries have slipped 4 percent to 7,842,580 tons.  Shipments from Ontario quarries total 1,950,646 tons, an increase of 233,000 tons.


Lake Carriers’ Association represents 14 American companies that operate 56 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, aggregate and cement for the construction industry, coal for power generation, as well as salt, sand and grain.  Collectively, these vessels can transport more than 100 million tons of cargo per year.  More information is available at
