A trip to the Chittenden Locks in Ballard in the fall is a good time to see salmon making their way up through the fish ladder en route to their spawning grounds. If we know the salmon are there, so do their predators. On this day, it was seals. Seals and sea lions are both common at the locks when hunting for salmon. A pair of seals were playing around in the waters near the locks, no doubt choosing their moment for a snack. Another pair of seals had been a bit more aggressive in their thinking. They had made their way into the fish ladder itself.
There are gates on the entrance to the ladder that are intended to allow the fish through and not the larger predators but I guess on this day, the gates had been left open. Our first glimpse on one of the seals was as it was chomping its way through a salmon it had already caught. It was making swift work of it. A while later we saw them again. They would haul themselves out on to the walls of the ladder for a break before diving back in to search for the next snack!
The salmon head to spawn in phases with the three different breeds coming at slightly different times. They head through the ladder at the locks in Ballard in the fall but, before they head into Lake Washington, they pause in the approach area. The transition from salt water to fresh is something that they have to adjust to and the area just by the locks where the fresh water is spilling out provides a good place for them to get adjusted. They can stay for a couple of weeks or more. The result was that we saw a lot of salmon swimming around in the waters by the dam. This was not a risk free occupation as shall be covered in a future post.
