Who We Are

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

This work is possible because of volunteers like you. Your voice is essential.

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

Who We Are

'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.' — Jennifer M., Watershed Advocate

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across industries to hold polluters accountable.
