Who We Are

Our work begins where rivers meet the sky and ends where groundwater feeds the soil. We use advocacy to protect it all.

This work is possible because of volunteers like you. Learn how you can join.

Who We Are

We believe that nature can heal if we remove barriers. Our 20-year track record shows that change happens.

Who We Are

'I used to think my voice didn't matter. Then I joined a citizen monitoring program and realized — my data prevents harm. Now I'm inspiring others.' — David T., Watershed Advocate

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across political boundaries to solve problems at their source.
