Summer Concerts at the Locks

 

Summer is here and it's time for the Ballard Locks concert season to start. Come on over and enjoy free concerts every weekend through the summer at Seattle's historic Chittenden locks. Bring your lawn chairs or picnic blankets and enjoy the music, watch the boats coming and going and watch the salmon returning. It's all free and is one of Seattle's best, family friendly events.

While most of the posts on this blog feature aspects of the locks and grounds themselves, or historical events, this post will mark a decided departure from past posts. This is an article where the Ballard Locks are really just part of the backdrop of one of the more dramatic stories we've come across. But the fact that the locks were involved in even the slightest fashion, is all the excuse needed to share a great story.


This is not a drill!

Crystal S crew being rescued by the Bering Sea

The above photo was taken by the cook aboard the Bering Sea as it reached the 5 crew members from the now sunken Crystal S after they had spent the last 3 hours sitting atop their overturned lifeboat after abandoning ship. Although the text accompanying the photograph mentions that they had spent 9 hours adrift, 3 hours seems more accurate, although it might well have been 9 hours until they were landed safely back on shore after the incident.

Before going into what's known of the details of the boat's sinking, let's look into the development of the most crucial piece of equipment which was the primary reason for this story to have had the best of all possible outcomes, given the boat's failure.

David Williams and Jennifer Ott new book launch at MOHAI

Book Launch at Mohai March 24, 2026 

 

Local authors David Williams and Jennifer Ott will be giving a presentation at MOHAI on Tuesday March 24, which will accompany their new book launch. Here's a link to the MOHAI post for further information. The event is free with registration by following the link. This is an updated version of their 2017 book, Waterway, which told the story of the construction of the Lake Washington Ship Canal and the Chittenden Locks. A highly detailed story of the project from it's inception in the late 1800's through it's construction, completion in 1916 and was published just before the Centennial Anniversary of it's official dedication on July 4, 1917.

The brochure below was created from historical maps and documents and was included in a time capsule for the Army Corps of Engineers, to be opened in 2075. It uses the same type of records and maps preserved and relating to the construction of the Ship Canal and Chittenden Locks. It gives a flavor of the historical value sure to be present in the author's new release.

Visitor Center Juvenile Salmon

 


Salmon smolt tank at Visitor Center



The Visitor Center has a new display for viewing until sometime in May. It is a tank of salmon smolt which will be kept in the tank until they reach a size where they can be released into Lake Washington, eventually to make their way into Puget Sound and parts unknown for the following few years. Here's a good chance to see them and wish them Bon Voyage before they head off.

Center Gates Removal

Jan 2024 Center Gate progress photo from Greg Shaw

 

 Here's something you might see every 107 years or so. The center gates at the large lock were being removed recently and will be replaced late next year. This will necessarily cause disruptions in the use of the large lock as it will be closed for extended periods of time until the new gates are installed. Here's a link to the Army Corps page with projected dates for the closures.

Large lock closure information 

 

Both gates were removed late in the night so the public missed a great photo opportunity but for several days it was possible to see the work crews preparing for the rarely performed procedure. We know the gates were removed at least once before in 1973, brought to Tacoma for repairs and reinstalled again. Here's a few pics of the process.

Using torch to burn through wood fender on gate

Axes, chainsaws, torches and crowbars were all used in cutting through the wood before installing the equipment used in lifting the gate from lock. on deck of the large crane was this smaller crane used in bringing the crew close enough to the gate to complete the process.



Here's a small video of a chainsaw in use to cut away a section of the wood fender.

In the meantime, the small lock also needed a little TLC.

While all employees were hard at work, there was one who was clearly just phoning it in.
