Tour boat out of Peterborough, Ontario
The tour boat is returning home, entering Lock 20 at Ashburnham on the Trent-Severn Waterway. It's early evening and the tourists have just been to the highest lift lock in the world, which is less than a kilometre north of this lock. The water in the canal on this side of the lock is approximately 3.7 metres (12 feet) higher than the water in Little Lake just ahead. So the boat must enter the lock to be lowered. Then the gates close behind it.
Water drains from the lock, lowering the boat
In the left-hand corner you can see the very back of the tour boat. The back gates to the lock have closed and some water has already been drained from the lock.
Nearly 3.7 metres (12 feet) of water inside the lock has now drained out of the lock
The boat will soon sail into Little Lake.
Opening the gates in front of the boat
As this Government of Canada employee pushes this lever as he walks around, the lock gates in front of the boat slowly open...
and the tour boat motors on.
