Three Riverkeepers, one mission.

What is a Riverkeeper?

Riverkeepers are the eyes and ears of the water, protecting the public's right to clean water in their rivers and streams. Encompassing the skills of scientists, teachers, law officers, fishermen and paddlers, Riverkeepers combine a profound knowledge of their waterway, matched with a relentless commitment to protecting your rights and the rule of law. 

Potomac Riverkeeper Network is the only nonprofit dedicated to protecting the entire Potomac Watershed through legal advocacy. We are home to three Riverkeeper branches:

Protecting the Shenandoah River, from Virginia to where it joins the Potomac River. Mark Frondorf Bio

Protecting the main body of the Potomac River from Harpers Ferry to Washington, DC. Dean Naujoks Bio


Our Riverkeepers are "boots-on-the-ground" and "boats-in-the-water", tracking down pollution single-handedly, bringing a voice to the people through educational presentations and community involvement, and speaking out for change in the courtroom to create stronger environmental protections.

As a member of Waterkeeper Alliance, we provide a way for communities to stand up to anyone who threatens their right to clean water—from law-breaking corporate polluters to irresponsible governments.
