Trent-Severn Waterway...Kirkfield Lift Lock...visit on August 27th, 2018

Boats from river A enter  this artificially created canal to go to river B. 

The short cylindrical thing you see on the side is where the boat is tied, when waiting for the lift lock to open. these cylindrical things are in a row, meaning that boats wait in line for lift lock to open.

The boat comes to this place and waits. Imagine this is a large tub of water on which the tub is floating.

Above, is the large tub like thing in which the boat is sitting. It is lowered slowly to the level of the canal which is the canal leading to the  river B.
