The Peterborough Liftlock is the world's highest hydraulic lift lock. It is Lock 21 of the Trent-Severn system and is a large unreinforced concrete structure that was designed to lift boats 65 feet (almost 20 metres). The lock operates on a balance system. Water is let into the upper chamber. Boats going down enter the caisson and boats going up enter the lower caisson. The pivoting gates are closed and locked. A connecting valve is opened and the heavier chamber automatically descends, forcing the lower chamber up. There is no external power needed. The lift lock functions by gravity alone, using the principle of counterweights.

opening day of the Liftlock |
My family has connections to the Lift Lock that go back to the early days of construction. My nephew, Ian worked summers on the Lift Lock while he was in school.
My Grandfather worked with his team of horses digging out the channel that would eventually be flooded to connect the two bodies of water that would be traversed by the liftlock.
Just before the Liftlocks was a railway swing bridge. My Great Uncle Matt lived close to the swing bridge and he operated that for many years. A boat would ring its' bell or blow its' whistle and Matt would open the railway swing bridge to let them through and then close it for the trains running on the line. We were told on the cruise that a Canadian National Railway employee bids on a contract to operate the swing bridge. These days, there are more boats going through than trains so the employee comes and closes the bridge when a train scheduled and during the night when most of the trains go through and locks don't operate.
During my childhood, I spent a lot of time with my Aunt Lil and Uncle Mait who lived just a block away along the railway line. I remember running to my second story bedroom window or along the tracks in the backyard, making the motion of pulling the whistle lever. The guys would always sound it a couple of times for me and wave. I loved it!
I also remember crossing that railway bridge with Uncle Mait when we were walking the dog. I was terrified. At the time I was just a slip of a girl and could have easily fallen down between the ties to the river. So not only did I never learn to swim but grew up with a fear of heights. Uncle Mait told me I was being silly and Tommy the dog was much smaller but very sure-footed. You can bet after a few of those walks, I refused to go on any more. I was never a shy child!
I love having grown up in Peterborough and recognizing how people and places here are woven together to form the tapestry that is my family.

We did the lift lock cruise last year and really enjoyed it. Even though we have been to the lift locks many times it was the first time we took the cruise. Lots of fun. I remember you mentioning your connection to the locks then. Sounds like you all had a fun cruise.
ReplyDeleteWe had a great time but I would avoid going on a Sunday. There were so many people from the GTA and they stood at the front of the boat for the whole 2 hours and made it difficult to take pictures. It would be quieter during the week. xo J
DeleteThat sounds like fun, especially if it was a really hot day. Anything to do with water at this time of year is sounding good. We are in the middle of a heat wave...lol.
ReplyDeleteIt was interesting to read about how your family is intricately tied up in the running, and building of the locks, you must feel a special bond with that.

Thanks Jen. It was a really hot day so I did have a cold beer from the bar as well. Lots of fun. We do have a lot of connections to the Liftlocks and many other things in Peterborough. I've never lived anywhere else and never wanted to but now I'm thinking a little place in the country would be perfect for my retirement years. xo J
DeleteAmazing that something built that long ago still functions so well. I'd like to take that cruise some time!
ReplyDeleteIt really is Maureen. There's always been repairs done but nothing major has changed. What amazes me is that the concrete wasn't even reinforced. xo J
DeleteGreat history lesson today. I enjoyed it. And fun, fun photos.
ReplyDeleteThank you for sharing.
