Helping to restore and protect the Susquehanna River watershed

The Freshwater Research Institute (FRI) is a collaboration of scientists, educators, conservationists and restoration practitioners within the Susquehanna community who are dedicated to understanding and improving the ecological health of Pennsylvania’s waters.

The FRI’s mission is to provide a student-centered experience that prepares undergraduates to achieve their personal career goals in research, conservation and restoration, and educate future leaders in the field of freshwater studies.

Real-World Experience Starts Here

Susquehanna River in the fall


The Freshwater Research Institute is walking distance from the Susquehanna River — the Chesapeake Bay’s largest tributary and the longest river on the east coast within in the U.S. We are also just a short drive to streams, reservoirs, creeks, wetlands and restoration sites.


The Freshwater Research Institute is located on the 87-acre field station, known as the Center for Environmental Education and Research. The CEER is also home to our beehives, solar array, ecology research plots, walking trails and riparian buffer restoration site.

Stream Ecology Institute for High School Students

At this weeklong summer institute, high school students will explore how a fish, an insect, algae and even an old tire, influence each other and are affected by one another in a continuum — from small streams to large rivers. You’ll engage in learning experiences about the environment and long-term ecological studies, as well as explore career possibilities in science and ecology.

Restoration Opportunities for Landowners

If you are a landowner in Clinton, Centre or Lancaster counties, this mapping tool can give you information about restoration opportunities on your land.

Chesapeake Conservancy

Chesapeake Conservancy

Susquehanna partners with the Chesapeake Conservancy on precision conservation, an approach to restoration on agricultural land that uses high-resolution, geospatial analysis to target and implement on-the-ground agricultural and conservation tactics.

Solar Array

Our 14-acre, 12,000 panel solar array provides 30% of the university’s electricity and when installed in 2018, was the largest university-sponsored solar array in Pennsylvania. Over 30 sheep from Owens Farm in Sunbury serve as our lawn mowers around the solar panels.

Climbing Temperatures Adversely Impact Brook Trout

Recent research from Susquehanna University’s Freshwater Research Institute finds that water temperatures affect certain behaviors in a cold-water predator, especially when in the presence of one that prefers warmer waters.

Susquehanna, Chesapeake Conservancy Formalize Relationship

Susquehanna University and the Chesapeake Conservancy have formalized their ongoing relationship through an agreement that ensures the organizations’ continued cooperation on restoration projects within the Susquehanna River watershed.
