Who we are and what we do
Sno-King Water Watchers is a community-based water monitoring program. Water Watchers use monitoring data to advocate for protection and restoration of streams, lakes, wetlands and natural areas: and to educate and promote public awareness of watershed health.



Volunteers sample streams monthly for water chemistry and bacteria. Volunteers evaluate streams annually for stream “bugs” which are long-term indicators of biological health.
Sno-King Watershed Council partners with Global Water Watch to train volunteers in water monitoring techniques throughout King and Snohomish Counties.
How you can help your streams
Urban streams are in peril. Stormwater pollution, sediment and contaminants have reduced streams capacity to support salmon and other native wildlife, and streams are often unsafe for human contact. You can learn about watersheds and streams and put your knowledge to work to help solve these problems.

Advocate – Use your voice to support policies and practices that retain trees, replace fish blocking culverts, promote stream restoration and protect wetlands.

Be WaterWise – Practice stormwater conservation at home by installing rain gardens, using a carwash, minimizing fertilizers in the yard, and properly disposing of animal waste.

Lend a Hand – Volunteer as a Water Watch monitor, Forest Steward, or other community engagement opportunity!
We conduct regular educational workshops, which include Introduction to Water Monitoring, Bacteriological Monitoring, Water Chemistry Monitoring, Stream Flow and Habitat Monitoring, Stream Biomonitoring and BIBI (Benthic Index of Biotic Integrity). You can find more information here: Upcoming training classes and events.
