Watershed Guardians

Our Work

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

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

Our Work

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

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

Our Work

'I used to think my voice didn't matter. Then I joined a citizen monitoring program and realized — my data prevents harm. Now I'm leading others.' — David T., Community Monitor

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