Our Mission

Every watershed tells a story of crisis. We're here to ensure that story has a thriving future.

This work is possible because of community members like you. Together we can turn the tide.

Our Mission

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

• Community science programs for local stewardship

The water that flows through you connects you to 7 billion people — and future generations. Protect it 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 inspiring others.' — Sarah K., Community Monitor

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.
