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.

Grab your family, friends and your running shoes for a commemorative Great Miter Retire 5K Fun Run at 10 am, Saturday, Oct. 7, 2023, at https://www.facebook.com/ChittendenLocks!

 

Our large lock center miter gates are the original gates and have facilitated navigation since 1916.

 

This October, we'll start work to replace them. Improving this 106-year-old navigation infrastructure will help us provide dependable navigation for the next 100+ years.

 

Walk or run along these engineering marvels one last time during this fun run that'll start and end at these gates.

 

Registration is now open. Click  https://www.discovernw.org/great-miter-gate-fun-run.html or scan the QC code, to register or for more info. 

 

All registration funds will go toward supporting new exhibits in our fish ladder viewing room.

Here's our upcoming extended large lock center gate closure schedule: Lock Closure Schedule

Lock Wall Roses at Small Lock Operating House Four

 Researched and written by Stephen Munro, gardener at the Chittenden Locks.

Operating House Four sits adjacent the small locks and is where lock attendants control
the valves and gates for those locks. Two large rose bushes seemingly burst out of the
desolate concrete of the lock wall monolith on the west and east sides of this structure.
The one on the west side is nearly thornless with large very fragrant double purple
flowers. The other, on the east side has large double pinks flowers that are also very,
very fragrant. Both appear to bloom seemingly all growing season from late-May to
September.

Feb. 2 - Anniversary of the First Filling of the Locks

This post was first published in 2018. We've added some new content below the original article. In the article from the Seattle Post Intelligencer it names machinist Carl Sjogren as the individual who actually opened the valves admitting water into the chambers. If there are any descendants of Carl Sjogren who see this post, please send any photos or information you might have of his time at the Chittenden Locks. We'd be happy to add yet more local flavor to this post.

Update

In our own archives we've discovered a group photo where Carl Sjogren can be seen. He's standing in the back row, second from the right. This picture is dated August 1932, for a yet unknown occasion. We've also learned that he started working at the locks in 1912, while they were under construction, until his retirement in 1944. In the 1920 Census he had apparently changed the legal spelling of his name to Seagren. His death occurred in July 1953 in Mount Vernon, an area where he had lived before starting work at the locks. Perhaps the local Nordic community might like to propose that next Feb 2, could be named Carl Sjogren Day, after the machinist who first opened the valves to begin the first filling of the large lock chamber. 

Bowfin Submarine

 

Bowfin Submarine

 

We were recently asked about information on this submarine, which was used as a Navy training vessel on Lake Union from 1960 to 1971. Specifically we'd like to find some photos of it's arrival or departure from Seattle, and especially if anyone might have a photograph of it while in the Chittenden Locks. We did find some articles from the Seattle Times announcing it's arrival and then it's departure a decade later. Look below for the articles. The first of which announced the arrival and expected time that it would be at the lock the following day. Surely lots of locals made the trip to see it and could share their memory of the day and hopefully a photo taken of the event.

Chittenden Lock officials announce lift to some COVID-19 restrictions

 

Some exciting news from our Corps of Engineers. This is copied from their website.

"SEATTLE --

U.S. Army Corps of Engineers officials will begin its next phases of the Hiram M. Chittenden Locks reopening plan which include setting dates for the first floor of the visitors center to open on April 23 and access to the pedestrian bridges beginning April 28. The public restrooms will remain closed until May 3.

The fish ladder viewing area will remain closed until further notice due to an upcoming maintenance project. The historical administration building will remain closed to the public as well.

The decision to reopen these parts of the property was made based on COVID-19 community data and safety considerations. Officials wish to make clear that if the COVID-19 situation in the community gets worse, the restrictions could go back into place for the safety of Locks employees and to ensure no disruptions to lock operations.

“We are happy to welcome our commuters back to the locks,” said project manager Jon Hofstra. “We understand that it has been inconvenient for our neighbors to find alternative routes and we thank everyone for their patience and understanding during this unprecedented time.”

Locks staff ask that commuters travel straight through and practice social distancing while crossing. Please do not stop and congregate to ensure continued safety for all visitors and staff.

The gate hours will be 7 a.m. to 9 p.m. beginning April 28.

As a reminder masks are required on all Federal property in or outdoors.

Before long, visitors will be able to view the fish ladder, cross the pedestrian bridges to the Magnolia side, and check out the exhibits in the Visitor Center. This comes with a warning that if the pandemic takes a turn for the worse, the access to all of this may change as necessary. So, observe all social and health protocols and enjoy some of what makes Seattle special at the locks.
