Potomac Watershed

The Potomac Watershed is the land area that drains rain and snow into the Potomac River, which flows into the Chesapeake Bay. Covering parts of Maryland, Virginia, West Virginia, Pennsylvania, and the District of Columbia, it spans approximately 14,000 square miles. The watershed includes forests, cities, farms, and wetlands that influence water quality and ecosystems. Protecting this area helps ensure clean water, healthy habitats, and flood control downstream. It’s important for drinking water, recreation, and supporting diverse wildlife, making sustainable management key for environmental health and community well-being.
