Sno-King Watershed Council operates a community-based water monitoring (CBWM) program, Sno-King Water Watchers, in King and Snohomish Counties. We are a part of Global Water Watch. From 2015 to 2024, we utilized the Global Water Watch database for entering and viewing data. You can still view that data here:
