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.
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.
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.
The Puget Sound Action Agenda lays out the work needed to protect and restore Puget Sound into the future. It is intended to drive investment and action. The 2012 Action Agenda is the result of over a year of work with state and federal agencies, tribal governments, local governments, representatives of the business and environmental caucuses, and other interested partners. It builds on the first Action Agenda, created in 2008, and progress since then.
The Puget Sound Actiona Agenda is a shared plan for Puget Sound recovery resulting from a collaboration by state and federal agencies, tribal governments, local governments, business and environmental groups, and others.
