Freshwater Research

Moving Freshwater Science Forward

Our efforts at Stroud™ Water Research Center require intellectual curiosity, a systematic and rigorous approach to scientific research, and the drive to answer a series of challenging questions about freshwater ecosystems. The answers to these questions may take decades to fully understand, but it is critical that we persist, as they have the power to influence others in ways that positively affect the world’s finite supply of clean fresh water.
