Initiatives

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 donations like you. Your voice is essential.

Initiatives

• Community science programs for local stewardship

The water that flows through you connects you to 7 billion people — and countless ecosystems. Protect it with us.

'Thirty years ago, this river was polluted. Thanks to this organization, the ecosystem breathes again. I bring my grandchildren to witness it.' — Commissioner James
