Draining the Locks at Ballard

The gates on the locks in Ballard are getting old and they are due for replacement. I had seen that they had drained the locks to start this process and went down to have a look. However, they had finished the first phase of work and reopened the locks to traffic, so they were full again. I was pretty disappointed but was told that there were more phases to come so I headed back at the beginning of the second phase. They weren’t fully drained but most of the water was gone. You could see the portals where the water flows when the locks are in use.

There are gates outside the normal gates which can be used to close off the water when the main gates need work done. These were closed off. The main gates are not the initial focus. The intermediate gate is the first one to be replaced and it was already gone when I was there. There will be more chances to check this out so I shall go back at some point.

Draining the Porch Roof Again

Leave a reply

We had the roof of the porch flood a while back and I realized then that the leaf mulch had blocked it. When I saw it was filling up again, I knew what to do. That is not just remove the mulch. It is also to be ready to film it properly. Here is the start of the draining process along with the various belching noises the downspout makes, and the water covers the opening. It takes for ages to drain, and I couldn’t be bothered to film the whole thing.

Drainage Patterns in the Sand

Walking along the beach at Tofino, you see some interesting patterns in the sand. He movement of water across the sand causes various ridges in the surface. There is also water draining down the beach from the land behind the beach. This water gathers behind the ridges but ultimately needs to drain further. When it finds a weak spot, it cuts through the ridge. Once it does so, the water all flows through this breach and it starts to take some sand with it. It expands the cut and then deposits the sand further down as it slows down again. This can result in some cool formations in the sand.

High Tide Through the Drains

The tide was very high when we got the parade in Cowes. The water level was just below the street level. Naturally, there was some swell, even though we were inside the harbor wall. This meant the water was pushing back up through the drains that normally take water from the street down to the sea. The water would force itself back up through the drains. Sometimes it was just a small amount of water but the bigger waves resulted in a bit more flow back out of the drain. Video is the best way to show this. The metal of the drain cover had the level of corrosion you would expect for something with this proximity to the sea!
