Initially, the icebreaking activity will focus on the lower St. Marys River, south of Munuscong (Mud) Lake and
the Middle Neebish Channel north and east of Neebish Island. As the week progresses, the Coast Guard extends
this icebreaking activity into the southern half of the West Neebish Channel, working from Mud Lake Junction
Light north to Moon Island. The Coast Guard will not disturb ice south of West Neebish Channel Light 45,
above Ferry crossing, or the ice north of Moon Island, below the Ferry crossing.
In the coming weeks, as the March 25th scheduled opening of the Sault Locks approaches, icebreaking
activities encompass all navigable waters of the St. Marys River. Recreational users of the ice should plan their
activities carefully, use caution near the ice and stay away from charted navigation areas.
