Entering off the Bay of Quinte, we welcome you to the Trent-Severn Waterway - stretching 386 km from Lake Ontario to Georgian Bay. Lock 1 is larger in size than standard locks and uses innovative wagon valves in the lock walls for more efficient dewatering. Built by the firm Larkin & Sangster, construction was complicated by the addition of a railway bridge immediately below the lock
