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

It's #fieldworkfriday but the rain has us keeping our cameras inside! We're sharing this photo from a sunny day earlier this week.

"Fresh water emerges at more than 1,000 springs in Florida. This water, flowing from the aquifer below, supplies more than 90% of Floridians with drinking water."

Remember that volunteer day we told you about doing invasive management work upstream from a series of buffers on Amish and Mennonite farms?

Here we are with our host Travis Martin and #WaterWeek founder Fritz Schroeder of @lancasterconservancy

We're celebrating #nationaltrailsday and #LancasterWaterWeek by volunteering!

Sunrise over a recently installed riparian buffer along a tributary to Little Conestoga. This buffer is a small one but important. It's the connecting buffer between five adjacent Amish and Mennonite farms, all of which have installed buffers on their land!

You can join Lamonte Garber from our restoration team this Saturday, June 5 for invasive management at the headwaters of this stream as part of Lancaster Water Week! Link to RSVP in bio.

How are we monitoring the changes by the addition of these buffers? Well that's where the science comes in! Our entomology team is sampling this stream to monitor changes in stream health!
