Interstate Commission on the Potomac River Basin
ICPRB was created by an Act of Congress in 1940 to serve, protect, and enhance the Potomac River basin and its tributaries. The organization is an agency of the member jurisdictional states consisting of Maryland, Virginia, Pennsylvania, West Virginia, the District of Columbia, and the U.S. Federal government. The organization is a quasi-governmental agency.
Our mission is to protect and enhance the waters and related resources of the Potomac River basin through science, regional cooperation, and education. Considered the “Nation’s River,” for more than six million basin residents, the river plays an important role in the lives of all. Through regional cooperation and partnerships, ICPRB is protecting the river and improving the quality of life in the watershed.
