The U.S. Coast Guard has begun salvaging a sunken barge and an overturned tugboat in southern Lake Huron.
Petty Officer Levi Read tells the Times Herald of Port Huron (http://bwne.ws/MOX3cS) work began at first light on Saturday.
The 110-foot dredging barge and the 38-foot tug were overcome in rough seas early Thursday about a mile from the Michigan coast and nearly six miles from the opening to the St. Clair River.
No one was hurt. Diesel fuel spilled into the lake, but officials say it's uncertain how much escaped.
Read says crews plan to work on the salvaging project all day Saturday and will continue to do so on Sunday if necessary.
Officials continue investigating what caused the sinking.
