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 new viewing sites in 2018 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.

Provide input on Chinook Winds restoration site on Duwamish River on May 24

The King County project design team is hosting a stakeholder meeting and design charrette to collect input on the Chinook Winds restoration site on the Duwamish River, just east of the Tukwila International Boulevard Bridge. The site, nearly six acres in size, presents a rare opportunity to replace a small portion of the vital wetlands and marsh that historically covered much of the valley, while also providing invaluable habitat to fish and wildlife that use the Duwamish River.

Thursday, May 24, 1-4pm in the Banquet Room at the Tukwila Community Center (12424 42nd Ave S, Tukwila, WA)

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! Keep current on current and forecasted conditions at:

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.

See it? Report it! Help stop the spread of invasives - with your phone!

An updated app from the Washington Invasive Species Council lets you report - via your phone: unusual sightings of potential invasive species, whether it’s a new plant taking over your local park or a strange fish you reel in. Once experts verify your report, it becomes part of a nation-wide system tracking invasives. Learn more at

Funding available!

The National Fish and Wildlife Foundation is accepting grant proposals for funding from the Killer Whale Research and Conservation Program (KWRCP), whose mission is to study and protect killer whales in the wild. Program priorities include supporting projects that increase prey availability, including “riparian and nearshore habitat restoration projects for Chinook salmon in Puget Sound.” Proposals are due July 13; eligible applicants include non-profits, state, federal and local governments, tribes, schools and businesses.
