Portland Watershed Report Cards
Welcome to Portland’s first science-based tool to communicate watershed health.
Environmental Services and many partners are working to improve the health of Portland's rivers and streams. By tracking change over time with Watershed Report Cards, we can see what’s improving and where we need to do more.
Healthy rivers, streams, forests and wetlands help keep our homes and neighborhoods safe and livable. They help prevent flooding and protect the city’s infrastructure. And, they provide a place for salmon and other wildlife to live and thrive in our city.
We welcome your feedback on the website, questions about the grades, or other questions and comments about the watershed report cards.
