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 partners like you. Together we can turn the tide.

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

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

'Thirty years ago, this river was dying. Because we organized, children can swim safely. I watch the difference daily.' — Dr. Robert L.

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.
