Safety Zone; St. Clair River; Port Huron, MI

The Coast Guard is establishing a temporary safety zone for navigable waters of the St. Clair River for 7.5 miles beginning in Port Huron, MI. Though this is an unsanctioned, non-permitted marine event, this zone is necessary to provide for the safety of life on these navigable waters during a float down event near Port Huron, MI. Entry into this zone of vessels or non-participants in the event is prohibited unless specifically authorized by the Captain of the Port Detroit (COTP) or their designated representative.
