SUSQUEHANNA RIVER BASIN COMMISSION Paul O. Swartz, Executive Director John T. Hicks, N.Y. Commissioner Scott J. Foti., N.Y. Alternate James M. Seif, Pa. Commissioner Irene B. Brooks, Pa. Alternate Jane T. Nishida, Md. Commissioner J.L. Hearn, Md. Alternate Major General Jerry L. Sinn, U.S. Commissioner Colonel Bruce A. Berwick, U.S. Alternate The Susquehanna River Basin Commission was created as an independent agency by a federal-interstate compact* among the states of Maryland, New York, Commonwealth of Pennsylvania, and the federal government. In creating the Commission, the Congress and state legislatures formally recognized the water resources of the Susquehanna River Basin as a regional asset vested with local, state, and national interests for which all the parties share responsibility. As the single federal-interstate water resources agency with basinwide authority, the Commission's goal is to coordinate the planning, conservation, management, utilization, development and control of basin water resources among the public and private sectors. *Statutory Citations: Federal - Pub.
