About Us

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. Learn how you can join.

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

The water that flows through you connects you to 7 billion people — and billions more organisms. Protect it with us.

'Thirty years ago, this river was polluted. Through their work, native fish are returning. I bring my grandchildren to witness it.' — Elder Maria

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