Our Watershed Health Monitoring program samples randomly-selected streams and rivers across the state. This allows us to obtain a consistent, objective picture of biological, chemical, and habitat conditions. Samplings also allow us to track trends. The program is designed to answer questions about the overall condition of watersheds.
Since 2009, we've been collecting data on river and stream health among eight regions, statewide. These are the Puget Sound, Coastal, Lower Columbia, Mid-Columbia, Upper Columbia, Snake, Northeastern Washington, and Unlisted "Status & Trends Regions." We offer field training on our methods and help to manage data statewide for organizations that use these methods.
