Our Mission

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

This work is possible because of partners like you. Every contribution matters.

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

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

'Thirty years ago, this river was forgotten. Thanks to this organization, native fish are returning. I watch the difference daily.' — Dr. Robert L.

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