What is the goal?

The overall goal of status and trend monitoring is to provide a regional assessment of whether collective stormwater management actions are leading to improved receiving water conditions in western Washington.

Where do we monitor?

SAM's receiving water studies occur in western Washington, specifically the Puget Sound and Lower Columbia River watersheds.

Three Puget Sound regional studies completed their first round of monitoring in 2015-2018. Learn more about Puget Small Streams and the Puget Sound nearshore studies.

Lower Columbia regional urban stream monitoring will start in 2020.
