WRIA 9 Partner American Rivers Publishes New Study!

Restoration supports Revenue! This is the lead finding from a recent American Rivers report on the Economic Outcomes of Urban Floodplain Restoration and shows that restoration of our urban rivers can result in positive net impacts to local and state budgets. In light of the economic impacts of COVID-19, it is critical to understand and articulate the economic outcomes of our efforts as we work to restore healthy, functional rivers, increase equitable access to open space and sustainably grow our economies in the future. Our intent is that this report can serve as a resource for communities as they develop plans and policies to achieve multiple benefits along their rivers.

This project would not be possible without our dedicated consultants from ECONorthwest and Environmental Science Associates the generous financial support of our partners at the King County Flood Control District, Watershed Resource Inventory Area (WRIA) #9, the Urban Waters Federal Partnership, The Russell Family Foundation and the Bullitt Foundation.

Swim Duwamish Video

In 2015, Mark Powell swam from the headwaters of Green-Duwamish River in the Cascade Mountains to the river’s end in the saltwater of Puget Sound. From June to October, he swam 85 miles from the meandering, pristine start of the river to the polluted superfund end of the river. This site chronicles his journey.

It's Salmon SEEson again!

It's Salmon SEEson again in WRIA 9! Stop by our suggested salmon viewing sites this fall to catch a sight of salmon returning upstream to spawn. Two newest viewing sites are at Miller and Walker Creeks in Normandy Park. Returning sites include Longfellow Creek, a few sites along the Duwamish River, the Whitney Bridge across the Green River, and the Soos Creek Hatchery.

thank you letter for Puget Sound Day on the Hill


Lobbying effort brings 60 Puget Sound recovery partners to DC

In this summary, Puget Sound Partnership Director Sheida Sahandy recaps the “Puget Sound Day on the Hill” effort in early May that brought dozens of recovery partners to Washington, D.C. to convey to members of Congress the value and importance of protecting Puget Sound. Among the attendees was Doug Osterman, WRIA 9 Salmon Recovery Manager. The summary recaps highlights of the event and provides a good update on the status of federal priorities for the Sound. Thanks to The Nature Conservancy, a website was created to share the many inspiring recovery projects taking place around the Sound; WRIA 9’s Maury Island and Quartermaster Harbor, Seahurst Park, and Duwamish Gardens are featured.

Washington's Senators advocate for salmon recovery funding

The Capital Building in Washington DCOn May 24, Washington Senators Maria Cantwell and Patty Murray, with other West Coast Senators, sent a letter to President Trump urging him to reinstate funding for the Pacific Coastal Salmon Recovery Fund (PCSRF) cut in the Administration’s FY 2018 budget. The Senators cite the progress made in salmon recovery with PCSRF funds and the critical role of salmon in the economic, cultural and ecosystem health of the region.

In mid June, the WRIA 9 Watershed Ecosystem Forum sent letters to all Republican members of the U.S. Senate and House of Representatives thanking them for their support for federal salmon recovery funding, and to urge them to reinstate and appropriately fund PCSRF to continue important progress in salmon recovery.

What will conditions be like in the watershed this summer?

Snowpack in the Cascade Mountains, Washington StateAs you no doubt noticed, our region just experienced one of its wettest and coldest winters and springs on record! Snowpack was abundant this year and regional water supplies are in good shape right now. However, NOAA predicts higher than normal temperatures for the Northwest over the next three months, with precipitation likely near normal. Remember that low flows and high water temperatures can affect salmon even if there is not a drought. And using water wisely is always a good idea to help fish!

GreenRiverGorgeGreen River Gorge Greenway, A Visual Journey

The Green River Gorge is located between the communities of Black Diamond and Enumclaw, connecting the foothills of the Cascade mountains to the Puget Sound lowlands of the Green River Valley. It's rugged remoteness creates a unique opportunity to preserve this wilderness landscape next to a growing urban area of over two million residents...if we act now. In 2016 Lisa Parsons hiked the entire 12-mile long Gorge and created an exhibition of photography, video, written word, and social medial outreach of the Gorge and her journey. Learn more at Lisa is looking for a variety of locations in the watershed to exhibit the work and give presentions on the documentary and her hike down the Gorge. Contact her at if you know of available venues.
