Site details

The Nordmeer was a 471-ft German steel freighter that ran onto Thunder Bay Shoal in November 1966 after turning the wrong side of the marker buoy. Once partially above water, the wreck has collapsed and now lies fully submerged in about 40 ft of Lake Huron roughly seven miles north of Thunder Bay Island, with the large diesel engine and big steel hull sections to explore. It is one of the most visited dive sites in Thunder Bay National Marine Sanctuary and suits newer wreck divers in calm conditions.
