This evening, 3 senior divers went in to assess Lock 23 for me... with the following news. Water temp 13C/56F. They wore 7mm wetsuits and were a bit chilled at the end (they're all pretty big guys). Total dive time 45 minutes - relatively speedy. Current strong, but not as bad as expected. Depth at …

June 2 Conditions at Lock 23
Spring is slowly moving forward. Water temperature today is 13C/56F, a slow start. Last year I was in the water (in my wet suit) on June 10: temp was 15C/59F. It might yet get there. The river is high. Higher than it's been for a while. Here is my photo gauge - from now on …
May 2019 Conditions at Lock 23
It's early May. Still chilly water averaging 8C/46F. Hardy dry-suiters have been in but I like to wait until the river hits 15C/60F (or close). Weeds are at their lowest point of the year - not much of a factor until at least mid-June, so chilly or not, it's an excellent time to see a …
Hydroelectric Plant Sluice Gates: 2018
Whoa! The extraordinary river flow of 2017 caused some pretty drastic long-term changes to the HydroElectric Plant route. Perhaps the most obvious is the change in the sluice gates. This is what they used to look like: But this is what they look like today! It appears I need to resketch my sketch! The boards …
Tanker “Chem Norma” Aground on Lock 23
Quite the start to the 2018 dive season! Larry and I were awakened in the wee hours of a recent clear night by the sound of a long, loud foghorn, followed by the frantic grinding of an engine in reverse. We looked out into the night but could see nothing amiss. In the morning the …
Dive Conditions Update
Along with anyone living in southern Ontario and Quebec this spring, we've been watching carefully the weather reports and specifically rainfall statistics... and we've been driving up and down the shorelines to inspect areas we know. There has been flooding and damage to many, many riverside properties. Lake Ontario levels remain higher than at any …

Middle Route: Rapide Plat Lock (1847)
The approach to the locks is described in this post. You want to arrive at either of position #2 or #3 described there. You'll pass over a tire (the only one in the entire site) and come upon a pile of bottles at the base of the lock's upstream gate. I'm calling it a "gate" …
Inner Route: The Hydroelectric Plant – From Plant Foundation to Tailrace
When you reach the foundations of the hydroelectric plant itself, you'll find bricks: lots of red bricks piled at the bottom of the plant's concrete wall with a few still partially affixed at its top. Pay attention to your direction at the top of the wall. Moving east over it with the current will carry you through the area of …

Top o’ the Wall: Between the Old and New Locks
In this photo, courtesy of stlawrencepiks.com, you can see the grassy section between the two locks. Starting upstream, note its important features: the initial curved approach wall, the dark rectangular and circular flower beds, the lock house in the centre, the position of the downstream Lock 23 gate, and the drop in depth where the wall curves inward, …
