SAULT STE. MARIE, MICH. – The Sault Ste. Marie Tribe of Chippewa Indians Natural Resources Division staff was notified at approximately 5:45 p.m. on Friday about a potential oil spill at the McKay Bay boat launch, east of Cedarville.

McKay Bay, just northeast of the Les Cheneaux Islands, is on Lake Huron.

Upon learning of the issue, staff immediately contacted local and tribal law enforcement and began coordinating with the Coast Guard on containment and cleanup efforts to prevent the spill from migrating to sensitive coastal wetlands.

An investigation into the cause and full extent of the spill is ongoing.

The boat launch is temporarily closed, and the public is asked to stay away from the area to allow staff to focus on cleanup efforts.
