GREEN BAY, Wis. — In accordance with federal waterway regulation 33 CFR 165.901, the Captain of the Port, Coast Guard Sector Lake Michigan is scheduled to close the waters of southern Green Bay to commercial vessel traffic starting at noon on Sunday, Feb. 1,2026.
This Great Lakes Regulated Navigation Area will impact all waters southwest of a line extending between the Peshtigo Reef Lighthouse and the Sherwood Point Lighthouse in Green Bay.
Closure to commercial traffic minimizes the risk to recreational users and facilitates winter activities, including ice fishing on Green Bay, and is set to remain in effect through the winter months while ice is present.
