A floodplain reconnection project is underway at the📍Big Quilcene River floodplain on the northeastern Olympic Peninsula!

The Jamestown S'Klallam Tribe is partnering with The Salmon Center and Jefferson County, WA Government to build a new bridge over the river, replace flood-prone parts of Linger Longer Road, restore the historic floodplain, and create logjams to slow the river. The effort will improve the Tribe’s transportation infrastructure, reduce flooding, and improve habitats to help salmon thrive. 🐟

The U.S. Environmental Protection Agency provided time-sensitive funding for design work that helped the project meet funding deadlines.

EPA’s Puget Sound Recovery National Program Office supports projects like this to uphold our Tribal trust responsibility and ensure a safe, healthy, and prosperous Puget Sound. Find out more at https://www.epa.gov/puget-sound.

in Portland, there is a small apiary where a group of honeybees have beachfront condos?! Along the Willamette River, sits a happy colony thriving as advances the cleanup of the Portland Harbor Superfund Site. The bees are used to pollinate the community garden and teach the youth about environmental stewardship.

Our Regional Administrator was happy to stop by and view the busy bees hard at work as we toured Cathedral Park.
