Canadian vacation pics

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!!  



Massive support piston. Had to be 6' across!!


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


View from the top.


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.


A bit about the locks if you can read it.


I google searched the locks & attached the findings so you can read more about these locks if you like. These pages will have answers I don't.

We were just above Toronto when you went lefty on that groundhog James.    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!!    Barry is on the other side of Canada.

Sorry Barry!! We never made it that far west.    Someday I would like to tho. I know you're neck of the woodless woods has some beautiful country too.

Thats pretty wild

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

Thats' pretty neat.  Must of been an American engineer that designed it

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. 
Here's a sample pic. I have more if anybody is interested in them.
