Diving notes

This is site for experienced divers.

The Roy A. Jodrey measures 194m (640’) in length. It lies near Wellesley Island to a depth varying between 58m (190’) and 73m (240’). The dive starts from the shore with a surface swim followed by a descent down to 12m (40’). From there, there is a line to follow down to 40m (130’). At that depth, many lines go to different directions. More directions are to come...

The Jodrey has been built in 1965 for Algoma Central Railway, a Canadian company. The ship was loaded with a 20,000 tons of steel to deliver at the city of Detroit.

On November 20, 1974 the ship hit a shoal in the Alexandria Bay which created a large opening while water was rushing in the boat flipped on its side and sank in less than 4 hours. The captain tried to sank the ship on the South side of the Wellesley Island but in vain. All the 29 crew members survived.

In 1988, the American Coast Gards supervised the refloating operations of eight barels of oil from the Jodrey. While...being the cause of small mysteries at Alexandria Bay, in July 1988, the Coast Gards then contracted a a crew for an underwater enquiry about the oil appearing at the surface of water above the wreck. On August 7, divers found eight oil barels on the bow at about 165 feet deep.

The first thing which strucks the diver at each dive are the titanic dimensions of the wreck. The Jordrey is still in very good conditions due to the depth which limits the diving and the stealing.

The main deck is below the 200 feet deep. At the middle of the wreck, there is fracture in the hull. On the bow, it is possible to see the rupture due to the collision with the shoal and the dammages caused by the descent along the cliff.

To dive on the wreck, it requires a large diving experience, adequate training and an adequate equipment for this type of dive. For security reasons, the diver should have received a Trimix training to dive on the site.

The Jodrey is located is an area where there is a high maritime traffic. A strong current is also observed on the site.

Driving directions

From highway 401, watch and take exit 675 leading to
Thousand Islands Parkway - Promenade des Milles Îles. Follow the road for about 2 km. Follow the directions for Mallorytown Landing and then turn on your left when arrived. Park your vehicule in the parking of Park Canada (there is a fee). If there is not more place to launch your boat or if you took arrangements with a dive operator located at Rockport, continue the road until there.


Alternative route. From highway 401, watch and take exit 661 leading to the State of New-York, USA, heading South. After few kilometers, you will have to cross the Canadian - US borders. It is recommended but not mandatory to registrer your equipment with the Canadian custom officier before crossing the border. This way while coming back you may have less trouble since your equipment will appear on the registration slip you then will have. To the American border officer you will have to answer any question he might ask about journey (have your passport). Once you’re done, follow the road now 81 toward Collins Landing. Then turn left on road 12 heading West toward Alexandria Bay. More informations are to come...
