These are some of the largest lift locks in the World. They work on a very simple system. The upper lock always has 1' more water in it than the lower lock to push the lower lock to the top. Works every time!! :biggrin:

The lock rests on the bottom here & the gates open to allow boats in/out.

This single lane tunnel runs under the entrance/exit of the upper locks. You can see the end of a liftlock ion the right upper corner.

We were just above Toronto when you went lefty on that groundhog James. :eyebrow: Matter of fact the text came in during breakfast. What a way to start a vacation day. A good late breakfast & a pic of a "good" hog in a text!! :yoyo: :yoyo: Barry is on the other side of Canada.
Sorry Barry!! We never made it that far west. :nono: Someday I would like to tho. I know you're neck of the woodless woods has some beautiful country too. :eyebrownod: :eyebrownod:
Thats pretty wild :congrats:
I dont understand though, why it would have to have so much travel. Is there like a 25 foot difference in the water levels or something :confused:
Thats' pretty neat. Must of been an American engineer that designed it :innocentwhistle:
There was a large piece of that canal built specifically for that liftlock. It was some thing like 7km long & the drop is actually 65'.
The link gives all kinds of pictures & useful information.
The designer was Canadian & He went to France Belgium & England to look at existing models. There is another set of these locks not far from Peterborough.
We even got a tour of an electrical generator plant on the same river. That was really cool. :biggrin:
Here's a sample pic. I have more if anybody is interested in them. :innocentwhistle:
