CHICAGO The Great Lakes
shipping season has begun, according to the Lake Carriers
Association of Rocky River, Ohio.
Over the next several weeks, 52
U.S.-flag lakers will return to service, ultimately spending
more than 10 months hauling iron ore, limestone and coal.
The St. Lawrence Seaway System
will open at the Montreal-Lake Ontario section and the Welland
Canal March 22, and the Sault Ste. Marie locks and canals will
open March 25, Canadian and U.S. seaway agency officials said
in their first 2013 notice to mariners.
Vessel transits will be subject to weather and ice
conditions and restrictions may apply in some areas until
navigation aids have been installed, the officials said.
