Every spring, hundreds of peamouth minnows, a foot-long fish native to Lake Washington, spawn in Kelsey Creek. Each spawning event is usually only 24 to 48 hours from start to finish. Be there at the right time and you may see a Great Blue Heron swallow a peamouth whole!
You can attend a Peamouth Patrol Workshop to learn about this remarkable event. But you can also sign up to volunteer - the best way to witness this wonderful sign of spring. Volunteers check the stream for fish for 15 minutes twice a week. In return, they get a text when fish arrive, so they are always the first to know.
