2022 Green River Chinook Salmon Returns

This year an estimated 5,587 adult Chinook salmon returned to spawn in the Green River. The relatively strong return exceeded the five-year average of 5,119 by 9% and was the largest return since 2018.  While this figure exceeded the current co-manager escapement goal of 2,744, it remains far below the established recovery target of 27,000.

Community Salmon Investigation for Highline volunteer displays a female Coho carcass

Miller and Walker Creeks Salmon Surveys - Miller/Walker Stewardship Program
In 2022, many rivers in Puget Sound experienced higher salmon returns and Miller and Walker Creeks within Normandy Park were no exception. Volunteers counted over 180 coho this year: the most returning adults since 2012! While these return abundances are exciting and encouraging, pre-spawn mortality remains an important issue for coho salmon in Miller and Walker Creeks, as well as other urban creeks in Puget Sound.

King County Chinook Wind Mitigation Project site

King County Chinook Wind Mitigation Project
The Chinook Wind Mitigation Project provides 6 acres of new estuarine habitat for juvenile Chinook salmon within the Duwamish. Although the new off channel habitat was connected to the mainstem river in August, additional riparian plantings will extend through first quarter of 2023. Riparian planting will be completed by Dirt Corps and King County's Green Start Training Program crews.

Volunteers at Duwamish Alive Orca Recovery Day 2022

Duwamish Alive Orca Recovery Day 2022 was held on November 19th by Green River Coalition and was a hit!
Despite the reschedule, plenty of volunteers and two partner groups attended the Duwamish Alive Orca Recovery Day held at Riverview Park in City of Kent. Orca Conservancy spoke about the Southern Resident killer whales and Long Live the Kings spoke about the salmon. This event was dedicated to restoration work at the Riverview Park. Partner’s presentations educated the volunteers about how the restoration work done that day helps the salmon upstream and orca downstream. We are all in this together, from the headwaters in the Cascades, to Elliott Bay!

The Duwamish Floating Wetlands project constructed floating wetlands (CFWs) to determine if they could increase salmon habitat
Completed by students at the University of Washington and individuals from the Green Futures Lab and Port of Seattle, the goal of this project was to increase salmon habitat and improve water quality to support the survival of out-migrating juvenile salmon in the Duwamish. Salmon smolts were observed resting and feeding, supported by invertebrates produced by the CFWs. Water quality analysis showed that the wetlands removed heavy metals. Through the COVID-19 crisis, local community members aided in monitoring and maintaining the CFWs and were critical to the overall success of the project.

Watch a short video about the project.

Longfellow Creek Floodplain Restoration

Longfellow Creek Floodplain Restoration
Longfellow Creek was once an important salmon stream in Seattle but due to historic development, its habitat and ecological functions have been dismantled resulting in high peak flows, flooding, erosion, channel incision, fish passage barriers and habitat degradation. Through the Longfellow Creek Floodplain Restoration project SPU will reconnect pieces of the creek to support salmon recovery, improves drainage, add resiliency to the creek, and invest in community needs. Through this project, SPU will evaluate the potential for creek and floodplain restoration at five locations along Longfellow Creek and likely advance restoration at 1-2 sites.

Contact Project Manager Arnel Valmonte with any questions.

English Hawthorn Tree

Nicoterra Trails - English hawthorn control
English hawthorn is a noxious weed that can form dense thickets, block animal movement, and obstruct restoration efforts. Nicoterra Trails is conducting a 4-year study on an existing patch of hawthorn trees at the Riverbend site in Tukwila. They are testing whether annual girdling will slowly kill established hawthorn plants while allowing the dying trees to provide bird habitat, shade, soil mulching, and other nursery-type benefits to new native conifer plantings.
