Lakes Limestone Trade Down 3.6 Percent in 2012

January 15, 2013

Shipments of limestone on the Great Lakes totaled 27,145,219 tons in 2012, a decrease of 3.6 percent compared to 2011. 

 

The trade was 7 percent below its 5-year average.


Shipments from U.S. ports fell 2.4 percent when compared to 2011, and slightly more – 4.1 percent – when compared to their 5-year average.  Loadings at Canadian quarries decreased 9 percent compared to 2011, and slipped almost 19 percent compared to their 5-year average.

Falling water levels and the dredging crisis took a toll in 2012.  By year’s end, a vessel that has carried as much as 35,457 tons in a single trip averaged only 29,796 tons on the three stone loads it moved in December.  The cargos were loaded at a quarry on Lake Huron and that body of water has fallen to a new record low.


U.S. ports: Calcite, MI, Cedarville, MI, Drummond Island, MI, Kellys Island, OH, Marblehead, OH, Port Inland, MI and Presque Isle, MI.  Kellys Island ceased shipping in fall 2009.  Canadian ports: Bruce Mines, Manitoulin Island and Smelter Bay (all Ontario).
