Cedar River Salmon Journey

Cedar River Salmon Journey

Where Hiram Chittenden Locks

When June 23, July 7, July 21, August 18, August 25, September 8 and September 15 at 11am–3pm

Join the journey of a lifetime. Free and family friendly!

Join volunteer naturalists at the Ballard Locks and at four sites along the Cedar River to see and learn about salmon. 

What do salmon need to thrive? Why is clean and cold water so important to their survival? Discover how you can help to keep these special creatures coming back to the river where they were born. See the salmon migration and learn about the epic journey that takes place every year as salmon swim from the ocean, through the Ballard Locks, into Lake Washington, and up the river to spawn. The Cedar River hosts chinook, sockeye and coho salmon among other fish species.

Summer: Watch the salmon migration through the Hiram Chittenden Locks in Ballard on June 23, July 7, July 21, August 18, August 25, September 8 and September 15, 11am–3pm.

Fall: See spawning salmon at one or all four locations along the Cedar River in the Renton and Maple Valley areas on October 6, 7, 13, 14, 20, 21, 27, and 28, 11am–4pm.

Sites include the Renton Library, Cedar River Park (behind the Renton Community Center), Cavanaugh Pond and Landsburg Park and Dam. Click here to view the flyer with directions.
