Coast Guard Cutters Mackinaw and Mobile Bay began icebreaking operations on the waters of Green Bay this week. The Coast Guard is preparing regional waterways for ship tanker movements. U.S. Oil is scheduled to resume the shipment of fuel products to the Port of Green Bay after ice is cleared for the ships.

These icebreaking operations will likely occur in areas used by recreational users such as, but not limited to, the Fox River Entrance Channel, the Sturgeon Bay Ship Canal, Menominee River Entrance, and the waters of Little Bay De Noc near Escanaba.

In the coming weeks, these icebreaking efforts will increase in frequency as ice conditions deteriorate and commercial navigation increases. All snowmobile, all-terrain vehicle (ATV) operators, ice fishermen, and other recreational users of the ice should recognize the instability of the ice. Additionally, they should plan their activities carefully and use extreme caution on and near the ice, especially in proximity to charted navigation areas.
