A dredge barge and its tug boat have sunk in Lake Huron. U.S. Coast Guard Lt. Justin Westmiller said the 110-foot dredge boat and a 38-foot tug boat started taking on water during stormy weather about two miles from the shore of Lakeport just after 4 a.m. Both boats then sank about 22 feet. The stern of the dredge barge and a portion of the tug boat is still visible in the water. The dredge boat was carrying between 1,500 to 2,000 gallons of diesel fuel, which is now leaking into the water.
