There will be more weeks with which to enjoy these scenes up close and personal but until you make it to the locks ... enjoy these. Thanks again, Emily!

Summer at the Locks

As summer is drawing to a close, it's worth reminding ourselves that we still have plenty more time to enjoy an outing at the locks. The concert season is continuing with jazz and classical music scheduled for Aug. 16 and 17 respectively and there is also a classic pre 1950's car show on the grounds on the 16th. Here is a link to the full schedule: Summer concerts and events at the locks.  

Some recent concerts featured latin music, a sedentary(!) marching band and a ukulele orchestra with a grab bag of genres.
Musica Molida

Relaxed Ukes

Ballard Sedentary Sousa Band

Here are some photos taken by a new volunteer, Kendra, at the recent fuchsia show.

Kendra also contributed these photos from a stroll around the grounds. Enjoy these and come down for your own stroll and enjoy the summer weather.

Greater Seattle Fuchsia Society

Our friends at the Greater Seattle Fuchsia Society have sent the following invitation to their upcoming show at the locks. This group has been volunteering at the locks for decades and are responsible for the fuchsia display you will find outside the Admin. building as you approach the locks. Some of the plants you will see have been developed locally and are named after local members of the society. So come and enjoy a day of all things fuchsia!

Fuchsias on display

47th Annual Greater Seattle Fuchsia Society judged show on

 For those who use the walkway to cross the canal please read the following notice taken from the Corps Facebook page. Be sure to check their page for further notices as more construction is planned for the summer.

Summer is coming to the Locks

As summer approaches, the locks will see a steady increase in visitors either walking the grounds or actually heading in from or out to the Sound. One of our volunteers, Emily Dunn, has provided us with more of her photos showing views of the locks as well as several pics from the garden. The smolt slides are installed to help start the young salmon on their sea journey. Two of the dam gates have been replaced so far and the rest will be replaced over the coming months. Those who choose to use the walkway for cross canal access should be alert to posted information on dates and times when the walkway may be closed. For now, here are some of our latest pictures and there will be more to follow as the summer progresses.

Managing water levels - The Hiram M. Chittenden Locks, Lake Washington, and the Cedar River

With spring runoff starting, winter floods behind us, and a record drenching March, as you walk over the locks, some of you may wonder where does all this water come from and how does the Corps of Engineers know how much to release or keep.

The water that leaves through the lock chambers, races under the tainter gates, or gushes through the fish ladder at the Hiram M. Chittenden locks has had a long journey by the time it hits the Puget Sound. Most of the water starts out as snow high in the Cascade Mountains slowly working its way down, over waterfalls, through turbines, meandering down a river, and then hanging out in Seattle before finally meeting the ocean. In this article we will take a brief look at the history of what role the locks has had on the watershed that drains through Salmon Bay and how and who manages the water levels.

Springtime at the Locks

While it's still a little early for viewing the annual salmon migration through the Chittenden Locks, the boating traffic is starting to increase (the small lock has been closed for the regular inspection/maintenance, but will reopen soon), the Carl English Garden has been busier than ever. Spring brings an outburst of new blooms and if you take your time walking through the grounds you can see some new arrivals. These photos were taken by Emily Dunn, a local high school student, who has provided us with many other garden photos while accumulating hours towards her community service. See how many of these flowers you can spot on your next visit.

Notice to Chittenden Locks marine traffic

We received the following notice concerning the annual closure of the small lock for it's maintenance and inspection procedures. Plan accordingly boaters. And for visitors and tourists, it is still a great time to visit and get a look at what it looks like below the water's surface.

Chittenden Locks small chamber closing 14 days for annual maintenance

SEATTLE - The Hiram M. Chittenden Locks small chamber will close to marine traffic from noon Friday, April 4, through 7 p.m. Friday, April 18
Crews will conduct maintenance and safety inspections during the small chamber pump out and closure. Foot traffic will not be affected and the large lock will continue around-the-clock operations for vessels. Lock wall staff will get commercial traffic through as quickly as possible.

All pleasure craft will use the large lock, and boaters should be prepared with appropriate equipment and crew. Large lock requirements include long lines and fenders on board. Current locking through information is available at Mariners may experience delays, depending on passage demand.

Most machinery and equipment, including the gates and valves, are original to the 97-year-old facility. The annual closure gives dam safety experts and maintenance staff an opportunity to dry out the chambers for thorough inspections and to make necessary repairs. This routine maintenance is necessary and important in keeping the Chittenden Locks safe and operational as the locks approach their 100-year anniversary.

The U.S. Army Corps of Engineers owns and operates the Chittenden Locks. The busiest in the nation, nearly 50,000 vessels lock through each year.
