“Most of the fish ladder plaza area and the ramp to the viewing room will be closed to the public,” states the US Army Corps of Engineers (USACE) website. The cleaning, which got underway yesterday, will wrap up on Friday, June 4th.
Each spring the USACE gets the fish ladder ready for thousands of adult salmon to migrate upstream to spawn. According to the USACE, approximately 33,702 sockeye, 5,082 chinook and 20,732 coho adult salmon made their way up the fish ladder last year on their way upstream.
Friends of the Ballard Locks has a great write-up on the history of the fish ladder and timing for salmon migration.
