St. Marys River, United States – On April 7, 2026, the U.S. Coast Guard Cutter Bristol Bay (WTGB 102) assisted the 656-foot motor vessel Federal Nagara as it navigated the icy waters of Lake Superior.

The cutter worked to break up thick ice along the river, creating a relief channel beside the vessel. This careful maneuver relieved pressure from the surrounding ice, allowing the motor vessel to continue its transit safely.

The operation highlights the vital role of ice-breaking cutters in keeping key shipping routes open during harsh winter conditions.
