Floodplains are the areas of low-lying ground adjacent to rivers, formed mainly of nutrient-rich river sediments and subject to flooding after storms and heavy snowmelt.

Can restoring the natural balance of the Nooksack River also reduce flood risks? Officials on both sides of the U.S.-Canada border are taking note as climate change raises the stakes.
This article provides an overview and a link to further information about the Floodplains and Estuaries Implementation Strategy. Implementation Strategies (Strategies) are plans for accelerating progress toward the 2020 ecosystem recovery targets for the Puget Sound Vital Signs. The Strategies are developed collaboratively with technical, professional, and policy experts and with local and regional input. They are funded by the Environmental Protection Agency.
A new approach to flood control is taking hold across Puget Sound. Rivers, scientists say, can be contained by setting them free. Conservationists hope this is good news for salmon recovery.
Floodplains by Design identifies floodplains in Puget Sound with multiple benefit potential and use information on flood risk to inform ecosystem restoration.
Synthesis of selected NEP Watershed Lead Organization grants administered by the Department of Ecology part 2
A 2023 report from the University of Washington Puget Sound Institute synthesizes past Watershed Lead Organization Program grants to support the EPA-funded Land Development and Cover and Floodplains and Estuaries Implementation Strategies. The report offers lessons learned from the habitat restoration and land acquisition-focused grants.
A pilot project to create a 'living dike' in Canada's Boundary Bay is designed to help a saltwater marsh survive rising waters due to climate change.
Puget Sound is often referred to as the second largest estuary in the United States behind only Chesapeake Bay, but its overall size may be less important than its complexity. The place is defined by the mixing of saltwater from the ocean and freshwater from creeks and rivers that create an almost alchemical transformation of habitat. In this article, we look at the geologic forces that formed Puget Sound and made it the dynamic system that we understand today.
How can Puget Sound generate more salmon? That question has been at the center of ecosystem recovery efforts for decades. But even as scientists and conservationists make progress on many fronts — from breaching dams to cleaning up the water — they have faced one especially complicated and frustrating limitation: Salmon need more estuaries. We look at how local tribes are working to restore this critical habitat.
Puget Sound National Estuary Program Synthesis of Integrated Floodplain Management in Selected Puget Sound River Deltas
A 2021 synthesis report from the University of Washington Puget Sound Institute synthesizes leading integrated floodplain management approaches to support the EPA-funded Floodplains and Estuaries Implementation Strategy.
Can scientists bring back the lost tidal forests of Puget Sound? It could take generations, but restoring this rare habitat will pay big dividends for Puget Sound’s salmon.
The Puget Sound River History Project at the University of Washington features historical topographic data for Puget Sound's river systems.
In recent decades, hundreds of millions of dollars have been spent to restore habitat for Puget Sound salmon. In this article, we look at how scientists are gauging their progress. Are environmental conditions improving or getting worse? The answer may depend on where you look and who you ask.
The Puget Sound Ecosystem Monitoring Program (PSEMP) is an independent program established by state and federal statute to monitor environmental conditions in Puget Sound.
As threatened Chinook populations in Puget Sound continue to lose ground, the state is looking to new strategies to reverse the trend. In the Skagit watershed, the scientists — and the fish — are among those leading the way.
A 2015 report from the Whatcom Conservation District and Whatcom County describes a pilot watershed characterization study focusing on the Terrell Creek and Birch Bay areas. The report and related appendices are available for download.
A 2015 report from the University of Washington provides the most comprehensive assessment to date of the expected impacts of climate change on the Puget Sound region.
An EPA-funded study by the Thurston Regional Planning Council identified recommended strategies and actions to protect and improve water quality and aquatic resources in the Woodard Creek Basin.
An EPA-funded study by the Thurston Regional Planning Council identified recommended strategies and actions to protect and improve water quality and aquatic resources in the McLane Creek Basin.
An EPA-funded study by the Thurston Regional Planning Council identified recommended strategies and actions to protect and improve water quality and aquatic resources in the Black Lake Basin.
Puget Sound is the second largest estuary in the United States. Today, we understand that estuaries—where freshwater and saltwater merge—are among the most productive places for life to exist.
Habitat restoration was undertaken in 2009-2010 on lower Hansen Creek, Washington. The project converted 140 acres of isolated floodplain into 53 acres of alluvial fan and 87 acres of flow-through wetlands.
