Our Focus is Fresh Water

Since 1967, Stroud™ Water Research Center has focused on one thing — fresh water. We seek to advance knowledge and stewardship of freshwater systems through global research, education, and watershed restoration.

What We Do

Future of Fresh Water Initiative

Goal: $20 Million

Nowhere else in the world is there an organization like Stroud Water Research Center, which has spent 51 years focused on understanding, preserving, and protecting fresh water. To strengthen ongoing research and to expand community empowerment programs to protect clean fresh water regionally and around the world, the Stroud Center has announced its Future of Fresh Water Initiative.


Help us reach our goal. Give to the Future of Fresh Water Initiative. Gifts to the Executive Director’s Fund and the Environmental Education Fund will be DOUBLED thanks to generous challenge grants!

Featured Initiatives and Partnerships

WikiWatershed® web tools offer watershed data visualization, geospatial analysis capabilities, and science-based predictions of human impacts on stormwater runoff and water quality.

EnviroDIY™ is a community where members ask and answer questions and network within interest groups to develop do-it-yourself environmental science and monitoring devices.

The Leaf Pack Network® is an international network of teachers, students, and citizen monitors using a simple experiment to determine the health of their local streams.

The Water Quality mobile app is a water-monitoring data-collection and learning tool designed for use by educators and their students, citizen scientists, and researchers.

The Society for Freshwater Science Taxonomic Certification Program ensures skilled persons are providing aquatic invertebrate identifications in North America.

The Consortium for Scientific Assistance to Watersheds provides free technical assistance to Pennsylvania-based watershed and conservation organizations.

Upcoming Events

Some activity by our friends, the beavers, along the West Branch of Brandywine Creek on a winter day.

Beavers are often called ecosystem engineers because they can radically alter stream or valley bottom ecosystems. Check out the link in bio to hear Stroud Center's Fluvial Geomorphologist, Melinda Daniels, Ph.D. talk about the benefits beavers can provide to a stream.

DID YOU KNOW? As ice and snow blanket our streambanks each winter, life still blooms in our streams! Water has a high specific heat capacity — water absorbs a lot of heat before it begins to get hot, and it resists changes in temperature even during the most wintry days. Although streams can freeze over, the ice is typically just a few inches thick and can provide extra insulation for the critters living below. As a result, the bottom of the stream can act a lot like a “streambed sleeping bag” for stream bugs and aquatic macroinvertebrates, who overwinter as larvae or eggs under rocks, leaves, and streambed sediments. ...
