Sault Sainte Marie, Mich. Saturday March 9 2019, the Coast Guard starts breaking ice in the lower St Marys River in preparation for the 2019 shipping season.

To date, icebreaking activity was limited to the lower St Marys River, south of Munuscong (Mud) Lake and the Middle Neebish Channel north and east of Neebish Island. This Saturday, the Coast Guard will extend their icebreaking activity into the southern half of the West Neebish Channel, working from Mud Lake Junction Light north to the south end of the Rock Cut. The Coast Guard will not disturb the ice north of the Neebish Island ferry crossing or south of West Neebish Channel Light 45.

In the coming weeks, as the March 25 scheduled opening of the Sault Locks approaches, icebreaking activities will 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.

If you have questions about local or regional icebreaking activities, you may contact the Vessel Traffic Service at (906) 635-3232 or via email at SOOTFC@USCG.MIL.
