I Accidentally Get Another Shot at the Lock Rehabilitation

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.

The Fish Ladder

Hiram M Chittenden was not only the man in charge of creating the Ballard Locks, he also was ahead of his time in understanding some of the ecological impact of what he was doing. The importance of the fish to the region and the disruption that the salmon would experience led him to the creation of a fish ladder. There is still one there now although it appears to be of slightly more modern construction.

There are ramps alongside parts of the ladder so you can look down and see the fish as they work their way up the steps. You can also look down and see a lot of them swimming around in the approach to the ladder itself. Meanwhile, there is a viewing gallery that has windows into the side of part of the ladder where you can watch the fish either resting in the quieter flows or forcing their way up to the next level. There were signs telling us which types of fish there might be but I have to admit they all looked alike to me.

Just north of the center of Seattle is Ballard. Aside from being an interesting area with shops, bars and restaurants, it is also home to a set of locks that connect the salt waters of Puget Sound with Lake Union and Lake Washington’s fresh waters. The locks are the busiest in the US with a steady stream of traffic. On the weekend, this is heavily dominated by pleasure craft but commercial vessels are also a big feature. Indeed, while we were there, we found out that there is a hierarchy of which types of vessel get to go through first, even if some of the owners of the small pleasure craft were not up to speed on the rules!

The locks are named after the man who was instrumental in the early phases of their construction. Aside from leading a big construction project, he also was quite visionary in other areas but that will be the topic of another post soon. There are actually two locks. One is a small lock that suits pleasure craft or small commercial vessels. The other is far broader and longer and can be operated with a middle set of gates if less vessels are coming through. It can also take a lot of smaller boats wedged together like a giant game of Tetris when demand is high such as is the case on warm holiday weekends.

The locks are open to the public along with a small botanic garden. You can cross over the top of the gates (although these are rather narrow and can get congested when people decide to stop and hang around rather than keep moving). There is plenty of space along the sides of the locks to watch the boats as they come in and as they rapidly rise or fall when the water levels are adjusted. We obviously weren’t the only ones to find it a relaxing spot to hang out for a while.
