Our Mission

Water doesn't recognize borders — and neither do the threats it faces. Our international teams work tirelessly to defend it.

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

Our Mission

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

• Disaster response for crisis zones

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

Our Mission

'I used to think my voice didn't matter. Then I joined a citizen monitoring program and realized — my data prevents extinction. Now I'm leading others.' — Jennifer M., Watershed Advocate

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