Dive Spot Guide•
Lock 28
Historic river drift dive on the Lock 28 canal route.
Best for advanced cold-water divers who can manage current, navigation, and a very small working depth band.
About Lock 28
Lock 28 is a fresh-water river drift dive on the old Galop Canal route in Cardinal, where the Weehawk entrance and the Conestoga line frame a short current-driven exploration of the lock entrance and adjacent structure. It is a compact, technical-feeling site that rewards good buoyancy, navigation, and a plan for the drift.

Local Intel For Lock 28
Community notes to help plan your visit.
Scuba Diving
This is a cold-water shore dive for divers who want a short but honest drift, not a long sightseeing swim.
Freediving
Not a practical freedive target because the drift is navigation-heavy and current-driven.
Snorkeling
The site is built around scuba drift and structure, not snorkeling.
