Hiram M. Chittenden Locks Subarea

Why is this Subarea Important to Salmon?

All salmon entering or leaving the Lake Washington/Cedar/Sammamish Watershed do so by passing through the Locks in Ballard. The locks are a partial migratory barrier for salmon, particularly juvenile salmon heading towards Puget Sound, and for adult salmon returning at periods of low flow. Fish access and passage barriers are complicated by high water temperatures and freshwater/saltwater exchange at the locks.
