The big lock at Ballard is undergoing a a renovation program where the gates are all being replaced. It is being done in stages and an earlier stage had me taking a trip across to see what I could see. That was in a previous post and it was a semi-successful visit. I was back at the locks over the Christmas holidays on a lovely sunny day when we took my mum out for lunch. As we walked across the small lock to the big one, I could immediately see that it had been drained.
The crew was working on the middle gates and the base of the lock was totally dry unlike last time. The low sun angle meant there was quite a bit of shade in the lock itself but it was still nicely illuminated. You could also get a good look at the ports along the base of the lock through which the water flows and, because the secondary gates were in place, you could see the large outflow ports downstream of the lower gates.
The depth of the locks is quite impressive. When you think how the water level is when it is full, you realize just how much water is in there and how deep it is if you are in something lightweight like a kayak! When you consider that the locks are over 100 years old, it makes the engineering involved in building them even more impressive. I will miss spending time here watching the boats traverse the locks – particularly on sunny summer days when the amount of traffic means the big lock gets filled up with the scores of pleasure craft. Fun times.
