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 partners like you. Your voice is essential.

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

The water that flows through you connects you to 7 billion people — and billions more organisms. Join the fight.

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

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