Lock 21 is an exciting and unique dive where you get to go back in time and dive a 19th century submerged Victorian canal lock on the St. Lawrence River. This dive can have strong currents and is best done by experienced 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.

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.

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

The St-Zotique underwater parc has four wrecks the Fédéral 11, The Teddy W, The Anne-Marie G, and the Fédéral 4, multiple anchors all linked togetther with cables so as not to get lost.

This is a great wreck dive on the Canada side of the St. Lawrence River. This is an easy shore entry and once you enter you can follow the 25 meter line to the wreck site. This is a 250 foot long wreck that sits in about 28 feet of water.

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.
