Puget Sound Stream Benthos


This site analyzes benthic macro­invertebrate community structure to determine the ecological health of streams.  Participating agencies use this site to manage, analyze and share data from their ongoing stream monitoring programs. Our goal is to store macroinvertebrate data in a manner that will allow for consistent comparisons among sites and programs over time. By working collaboratively with multiple jurisdictions and sharing data via the site, we hope to increase the value of our collective efforts.

This site was developed by a group of agencies interested in monitoring the health of streams in the Pacific Northwest. The City of Seattle, King County, Pierce County, and Snohomish County worked collaboratively to create a database system that allows sharing of benthic macroinvertebrate data among organizations and provides tools for calculating metrics and indices. We are actively using this site to store and analyze data from ongoing macroinvertebrate sampling programs. Also, we recently added historical benthic macroinvertebrate data collected by 17 other organizations in the Puget Sound Region (view report).
