Dive-site story
Flowing south out of Lake Huron along the border between Ontario and Michigan, the St. Clair River provides a high-energy freshwater drift dive. Divers drop into brisk current over gravel beds, submerged riprap, and clay bottom formations. The riverbed collects historic bottles and lost artifacts dating back through centuries of heavy shipping, alongside resident river fish that shelter in the eddy lines.
