Duluth, MN (NNCNOW.com) --- Thick ice formations on the Great Lakes limited iron ore shipments in March to 1.1 million tons, a decrease of 43% compared to a year ago, the Lake Carriers' Association said. Shipments leaving the U.S. Great Lakes ports fell by 52%.
The ice on the lake, along with sub–zero temperatures, caused the problems. They further add that some of the ore loaded in March did not reach its intended destination until April.
"Two vessels that departed Duluth/Superior at the western end of Lake Superior on March 26 did not arrive in Gary, Ind., until April 7," Lake Carriers' Association said.
Normally the near 800 mile trip only takes about 62 hours. Through March there's been a 33% decrease of the Lakes ore trade. This would have been a larger decrease had it not been for iron ore shipped in February which is not usually done.
