The 202 ft. sidewheel steamer Keweenaw - Built 1866 at Marine City, Michigan


Underwater Preserve

The Keweenaw Underwater Preserve was established by the State of Michigan in 1991 in order protect the area's submerged historic resources and to help divers to responsibly enjoy the area's shipwrecks. Information about these vessels and their remains is presented here to increase interest in protecting and preserving these and other historic Keweenaw wrecksites. For years these wrecks were slowly deteriorating due to vandalism and neglect. Now however, these historic wrecksites attract many divers and historians to the area and help build the local economy.

Remember, it is illegal to remove anything from most Great Lakes shipwrecks and you can be prosecuted for doing so. Although not all wrecks on this site are actually in the Preserve, they are all still protected from illegal salvage by Michigan State law, and all are closely monitored. Many of these wreck locations were kept secret for years out of fear that they would be looted or damaged. Please respect the decision to publicise these historic wreck locations for your diving enjoyment by not stealing from them or damaging them.
