Community Day and Salmon Spawning at Longfellow Creek

  • Dragonfly Garden 4107 28th Avenue Southwest Seattle, WA, 98126 United States (map)

Join us as we walk a section of Longfellow Creek in West Seattle to investigate the health of one of our local salmon runs. Longfellow Creek, which flows from Roxhill Bog to Elliot Bay, provides spawning habitat for a population of coho salmon every year.

A group of dedicated volunteers is working with Soundkeeper to monitor whether the coho in Longfellow reproduce successfully or succumb to stormwater pollution in the river and die before spawning (a phenomenon known as pre-spawn mortality). Every day for the duration of the salmon run, teams are documenting their observations of live coho and dissecting the dead carcasses to check spawning condition. Come join our Saturday group of volunteers and see them in action!

Also at the event will be groups from the Nature Consortium, Delridge Neighborhoods Development Association, King County Conservation District, and the City of Seattle to talk about wetland recovery, native plants, rain gardens, and what Seattle is doing to reduce the effects of toxic stormwater runoff on salmon populations and other wildlife.

This is a great way to observe one of nature’s most amazing migrations, get a taste of scientific field work, and learn more about what you can do to restore the health of our local waterways.

Equipment: Be prepared to get dirty. Wear athletic clothing and shoes that can get wet. We will be walking along the creek through some muddy areas.

Date: Saturday, November 5th

Time: 11:30am to 1:00pm

Location: Dragonfly Garden, 4107 28th Avenue SW, Seattle 98126
