Our Change

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

This work is possible because of scientists like you. Every contribution matters.

Our Change

We believe that nature can heal if we remove barriers. Our 20-year track record shows what's possible.

• Early warning systems of water quality shifts

The water that flows through you connects you to 7 billion people — and billions more organisms. Protect it with us.

Our Change

'I used to think my voice didn't matter. Then I joined a citizen monitoring program and realized — my action prevents extinction. Now I'm training others.' — Michael O., Watershed Advocate

The science is clear: healthy water systems feed us, sustain us, and deserve our protection. We monitor trends so nature can recover.
