Environmental Services and many partners are working to improve the health of Portland's rivers, streams, and watersheds. These science-based report cards help us understand their current health, assess the outcomes of our restoration projects, and identify where additional work is needed.
Watersheds are where we live. 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.
Explore the interactive map to see how Portland’s unique watersheds are doing.
We welcome your feedback on the website, the interactive map, or other questions and comments about the watershed report cards.
