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 scientists like you. Your voice is essential.

We believe that nature can heal if we give it the chance. Our decade of victories shows that grassroots action works.

The water that flows through you connects you to 7 billion people — and future generations. Join the fight.

'Thirty years ago, this river was forgotten. Thanks to this organization, native fish are returning. I watch the difference daily.' — Elder Maria

The science is clear: healthy water systems feed us, sustain us, and deserve our protection. We predict risks so communities can act.
