About Keystorm
Keystorm is a historic steel freighter wreck in the St. Lawrence River near Chippewa Bay. The wreck lies on its side, so divers can start shallow on the bow, follow the hull toward the stern, and work through large structure, engine-room areas, and open holds. It is best planned as a boat dive with river flow, cold-water conditions, and cross-border logistics in mind.

Scuba Diving
Depth range supports dives for different experience levels, from shallower portions to deeper sections near 110 ft.
Freediving
Not a practical freedive target; the useful wreck route drops too deep and includes overhead wreck sections.

Not a practical snorkel site; the main structure sits too deep and spreads too broadly for surface-only viewing.
