UNDATED (WSAU-Wheeler News) The Great Lakes shipping season ended overnight, after the locks closed at Sault Sainte Marie along the Canadian-and-Upper Michigan border.
Officials estimate that last year's shipping on Lake Superior was 1-to-2 percent higher than in 2012.
Jim Sharrow of the Port Authority at Duluth-Superior predicts higher activity in the New Year, as iron ore shipments -- one of the basic cargoes at the harbor -- will be busier again. The next shipping season begins when the Soo Locks re-open on March 25th. In the meantime, Sharrow says crews in the Twin Ports will be working on at least 10 freighters over the next two months.
