Watershed Guardians

Our Work

Water doesn't recognize borders — and neither do the threats it faces. Our regional teams work year-round to protect it.

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

Our Work

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across political boundaries to rebuild what was lost.

Join thousands of water guardians pushing back for justice.

Our Work

'Thirty years ago, this river was forgotten. Because we organized, the ecosystem breathes again. I work alongside their team.' — Professor Chen

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