The King County Flood Control District (KCFCD) is proud to announce the successful allocation of over $12.2 million in grant funding through its 2025 Cooperative Watershed Management (CWM) Grant Program. This essential investment will support dozens of habitat restoration, salmon recovery, and water quality improvement projects across the region’s critical watersheds.

Now in its 13th year, the CWM Grant Program remains a vital tool for advancing locally led, scientifically grounded watershed restoration efforts. In 2025, the program received 99 project applications totaling more than $21.5 million, far exceeding available funds and demonstrating both the need and enthusiasm for environmental restoration work throughout King County.

City of Tukwila and King County Flood District Partner to Preserve Critical Duwamish River Property

The City of Tukwila and the King County Flood Control District today announced the successful transfer of the former George Long Property, located at 14800 Interurban Ave South in Tukwila, WA, for $4.5 million. The acquisition preserves over three acres of critical shoreline along the Duwamish River, opening the door for potential future uses including flood risk reduction, habitat restoration, and public access to the river.

"This acquisition marks an important step in safeguarding the safety and health of the Duwamish River and the surrounding community," said King County Flood Control District Chair Reagan Dunn. "By securing this property, we’re not only preserving critical shoreline habitat—we’re also creating the opportunity to thoughtfully consider its best future use as part of our comprehensive planning for the Lower Green River Corridor.”

The Lower Green River Corridor Flood Hazard Management Plan is a comprehensive, multi-year effort led by the King County Flood Control District to reduce flood risks while also enhancing fish habitat, improving public safety, and supporting local communities. The plan is being developed in partnership with Tribes, local and county governments, businesses, and area residents to ensure an inclusive, science-based approach that balances flood protection with ecological restoration and other multi-benefits.

Abundance of Pink Salmon May be Harming Orcas

Pink salmon now comprise nearly 80% of all adult salmon in the North Pacific. This record abundance is coming at a cost to other salmon species such as threatened Chinook, which compete with pinks for spawning territory. A new study shows that the ecological toll may extend all the way to endangered southern resident killer whales.

Port of Seattle’s Elliott Bay Hydrophones Launching in July!

port

The Port of Seattle will launch an underwater noise assessment program in July. Acting on its commitment to better understand the underwater soundscape and reduce its negative effects on marine life, the Port has partnered with underwater acoustics specialists to deploy two hydrophones in Elliott Bay. Over two years, the team will collect, analyze, and report on continuously recorded acoustic data to establish a multi-year baseline. They will also assess the impact of maritime activities on the underwater soundscape and use the baseline data to set actionable noise reduction targets. Read their blog to learn more!

SHADOW Lake Nature Preserve is Providing Critical Filtration to the Greater Seattle Area

SHADOW Lake Nature Preserve is home to a 10,000-year-old peat bog that provides critical filtration ecosystem services to the greater Seattle area and the Salish Sea. While standard garden soil can only filter a quarter of its weight in water, peat can absorb twenty times its weight in water, making it especially well-suited for filtering out water pollution. Water from the bog drains into a tributary of Jenkins Creek, which then flows into Soos Creek, the Green River, and then to the Salish Sea, providing clean water to the Green-Duwamish River Watershed and creating healthy salmon habitat.

Chinook salmon (also known as king salmon) are listed as threatened under the Endangered Species Act. In WRIA 9, citizens, scientists, businesses, environmental and community organizations, and local, state and federal governments are cooperating on protection and restoration projects and have developed a science-based plan to conserve salmon today and for future generations. Funding for the salmon conservation plan is provided by 17 local governments in the watershed. For more information visit our website at www.govlink.org/watersheds/9/.
