Watershed Health Monitoring
Ecology's Watershed Health Monitoring (WHM) project collects data on river and stream health by region and has done so since 2009. This project was recently also known as the Status and Trends Monitoring for Watershed Health and Salmon Recovery project or WHSR. Approximately 50 sites are sampled per region in each round of sampling.
The WHM project also offers services to the public for objectively assessing watershed health. These include standard protocols for monitoring rivers and streams, training on these protocols, the Washington Master Sample site set, and the WHMWeb database for managing stream habitat data.
