On 4/5/1999 1, the vessel ALGONTARIO (Official Number 320490) was involved in a sank - founders (taking on water above the waterline) in NEEBISH CHANNEL, VICINITY JOHNSON POINT, ONT.,.

The vessel, with 20 persons on board, experienced the incident while engaged in regular operations. Fortunately, the ship was able to continue its voyage. No injuries or fatalities were reported, and there was none pollution.

This incident was officially recorded by Transport Canada on 4/7/1999 8. Weather at the time was reported as clear with winds from the E at 10.00 knots.

In the early morning of 5 April 1999, the Algontario was upbound in the St. Marys River. With the vessel abeam of Johnson Point light, the helm was put "hard to port" to make a 63º alteration of course into the Middle Neebish Channel. The vessel's turning circle increased and the rate of turn decreased due to squat and bank suction effects. The vessel overshot the turn for the deep channel and grounded in the 6.4 m (21 ft.) project depth channel between buoys Q20 and Q22. The channel was closed to upbound traffic until the vessel was refloated. Underwater surveys revealed that the hull suffered extensive damage to the bottom plating. The vessel was later dry-docked for temporary repairs.
