Interstate Commission on the Potomac River Basin
The jurisdictions include the states with territory within the Potomac basin, and the District of Columbia, entirely in the basin. ICPRB works with the jurisdictions and federal government to encourage cooperation on Potomac issues, such as the need for basin-wide comprehensive watershed and resource management. Each jurisdiction has its own programs to address diverse watershed-related issues.
