Stormwater Action Monitoring (SAM) conducts status and trend monitoring in Western Washington streams and nearshore marine waters.
In 2015, the condition of Puget Lowland streams was evaluated by collecting data for stream benthic invertebrates, periphyton, water quality, sediment quality, instream and riparian habitat, and land cover data across the region.
King County recently published the final report; Stormwater Action Monitoring Status and Trends Study of Puget Lowland Ecoregion Streams: Evaluation of the First Year (2015) of Monitoring Data. This large effort was coordinated by the SAM Coordinator and included staff from King and Skagit counties, San Juan Island Conservation District, U.S. Geological Survey (USGS), Ecology's Environmental Assessment Program, Puget Sound Partnership, and a myriad of laboratories.
The science team's recommendations for the streams trend monitoring program are included in the report. The Stormwater Work Group (SWG) will make adjustments to the SAM Puget lowland stream monitoring program based on recommendations from the report and further discussion by the SWG's committees.
SAM's stream study collects water, sediment, and benthic macroinvertebrate samples from Puget Sound lowland streams. This study tracks pollution and indicators of stream health trends over time.
