Coast Guard Sector Sault Ste. Marie, Michigan, plans and runs Operation Taconite, which includes all of Lakes Superior and Michigan, the northern half of Lake Huron, the St. Marys River and the Straits of Mackinac.
During the 160 days of the operation, nine U.S. Coast Guard and three Canadian Coast Guard icebreakers spent more than 5,000 hours breaking ice for convoys and assisted in 946 commercial vessel transits that moved an estimated 33 million tons of dry bulk and liquid cargoes, valued at $1.2 billion. These commodities were crucial to sustaining industrial production and power generation for the Great Lakes region during the winter months. Icebreakers provided direct assistance for 517 of the transits.
An additional 5,597 hours of icebreaking established and maintained tracks through the ice-choked waterways of Georgian Bay, Straits of Mackinac, Green Bay, southern Lake Michigan, St. Marys River, and across Lake Superior.
