We spent a wonderful day Saturday touring Seattle. The weather had given us a break, we were now enjoying warm sunny days. Our nephew Jonathan, his wife Allyson and son Sawyer joined us for the day. Jonathan proved to be an excellent tour guide. He has lived in the Seattle area for at least ten years, and Allyson grew up here. Our first stop was the canal and Hiram M. Chittenden Locks. The six mile navigation channel connects Lake Washington with Puget Sound. The dam and lock system at the west end of Salmon Bay raises the bay's level 21 feet. These locks are one of a few in the world which have a fish ladder where fresh meets salt water . As salmon migrate upstream to spawn they need to pass through the locks and dam, so in 1916 the first ladder was built for the salmon. There is a viewing gallery behind the ladder to see the fish coming through the series of steps. At present the large fish have already done their migrating for spawning and there are only fingerlings coming through. The time of the year makes a difference as to what size fish you will view here. Below is a picture of a part of the ladder. The fish that come in this ladder are shot through tails first. Looked a bit rough to me, but I guess fish are use to rapidly churning waters.
