Sure it does... I lived in St.Catharines for 28 years and fished that spot probably a thousand times. It's always been called 'the breakwall'. But apparently that terminology is incorrect, perhaps some people here need to go down there and educate the locals on their choice of words. I hope they bring a camera, because I'm willing to bet they'll be going for a swim
The fun times down there was fishing from the center section of the dam, the far left side with all the giant concrete blocks (past the fence) or the 3 falls. I can't count the number of times I got spooled there. Ride down in the morning before it was light on your bike with your fishing rod strapped to the frame, great memories!
