Puget Sound Stream Benthos

Stormwater Action Monitoring for Puget Small Streams, Washington State Department of Ecology

Stormwater Action Monitoring (SAM) conducts status and trend monitoring in Western Washington streams to answer how stormwater runoff from a broad range of urban conditions affects the health of small wadable streams.

The Puget Small Streams (PSS) study collects water and sediment chemistry, in-stream and riparian habitat information, benthic macroinvertebrate, and periphyton samples.

Sites are selected following a random probabilistic survey design which allows spatial characterization of large areas across the study region that would not otherwise be possible.
