Cheboygan, United States – Heavy machinery and two marine vessels are operating upstream of the Cheboygan Lock and Dam Complex at Mullett Lake to remove debris and break up ice.

The work is part of ongoing efforts to keep water moving through the system.

Crews are using equipment on both land and water to clear blockages forming in the area.

The operation is focused on managing ice buildup and debris accumulation upstream of the dam complex.

Authorities say the work is continuing as conditions require attention to maintain proper water flow.
