New to SWG? Watch this ten-minute introductory video for a brief history and explanation of the Stormwater Work Group and Stormwater Action Monitoring, posted on Ecology’s YouTube page. 

Who is your SWG representative? Find out here.

Our goal is to support efforts to restore the Puget Sound ecosystem and protect water quality and stream habitat throughout western Washington with a sustainable, cooperative stormwater monitoring and assessment framework that provides actionable information for stormwater managers, promotes greater understanding of harm caused by polluted and erosive runoff, and enables us to know whether and how effectively we are reducing stormwater impacts. 

We oversee Stormwater Action Monitoring (SAM), the regional stormwater monitoring program funded by municipal stormwater permittees. Watch the video explaining SAM and why it's important. See descriptions and deliverables of SAM studies, and budget reports, at ecology.wa.gov/SAM.

SWG was the first work group to be formally included in the Puget Sound Ecosystem Monitoring Program (PSEMP). Our geographic scope extends to southwest Washington.
