What is the goal?
The overall goal of the status and trend monitoring program 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 monitoring program focuses on two regions: Puget Sound and Lower Columbia River.
Three Puget Sound regional studies completed their first round of monitoring in 2015-2018. Learn more about the studies in Puget lowland streams and Puget Sound nearshore.
Lower Columbia regional urban stream monitoring will start in 2020.
