Our Focus Is Fresh Water

Who We Are

Since 1967, Stroud™ Water Research Center has been focused on one thing — fresh water. We are dedicated to understanding the ecology of streams, rivers, and their watersheds — both pristine and polluted.

What We Do

The health of freshwater ecosystems is our first line of defense in preserving clean water — and clean water is essential to all life. Our freshwater research, education, and watershed restoration programs enable businesses, policymakers, landowners, and individuals to make informed decisions that affect water quality and availability around the world.

How You Can Help
