Our Watershed Health Monitoring program samples randomly-selected streams and rivers across the state to obtain a consistent, objective picture of biological, chemical, and habitat conditions and 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.
The success of much of our environmental work hinges upon the health of the watersheds that support the natural environment, communities, and the economy. We monitor watershed health by studying various indicators, including water quality, and biological, riparian, and landscape indicators. We follow strict measurement, quality control and data management, review, and validation procedures to gain an accurate picture of watershed health.
