In 1958 the St-Lawrence seaway was created. The depth of the seaway was increased to allow larger ships to travel to the Great Lakes. As such many villages, road ways, locks, power houses, canals were submerged and can be seen by divers.

A great site to dive the historic Locks of the St. Lawrence River. This site is accessible from the Canadian side of the river. A nice dive for beginners as there is no current and the depth is shallow.

Multiple entry points. There is a wall drop-off where you can enter, but the site can also be accessed from an easy gradual shore entry point (near the wreck of Wee Hawk). This is a shallow drift dive that can end up at the Conestoga Wreck.

The Wee Hawk wreck is very deceiving and should be viewed from the exterior; it is located in very shallow and calm water. Penetration should not be attempted without proper training.

This site was set up by the City of Prescott. It has easy access and a nice set up for divers. The area is shallow with calm water. Bottom composition is silt.

Touted in Augusta as the “World’s Best Fresh Water Scuba Diving,“ this Rothesay dive and picnic site offer a great day-use area with easy access to amazing freshwater diving. The water clarity is excellent with no thermocline.

This dive site is in the old Canal Soulange (no longer in use). It has an interesting location near Parc des Ancres (where you will find many old ship anchors). The site is shallow with very calm water. As such, it is easy to silt it up so take caution.

The St-Zotique underwater park boasts four wrecks: the Fédéral 11, The Teddy W, The Anne-Marie G, and the Fédéral 4. There are multiple anchors all linked together with cables so divers do not get lost.

It is best to dive the wreck of Robert Gaskin from a dive boat. The dive can be done from shore but requires a long swim and a diver that has a very low SAC. It is located at Brockville, Ontario / N44°35’21.48“ W75°40’37.4988“, more information is available at https://saveontarioshipwrecks.ca/buoysites/robert-gask
