The Washington, DC, metropolitan area experienced unusually dry conditions in the summer and fall of 2023, and flows in the Potomac River fell to levels requiring the Interstate Commission on the Potomac River Basin (ICPRB) Section for Cooperative Water Supply Operations on the Potomac (CO-OP) to conduct drought response activities in support of the major regional water suppliers: Fairfax Water, Loudoun Water, WSSC Water, and the Washington Aqueduct, a Division of the U.S. Army Corps of Engineers. This report provides a brief summary of these activities and of related issues and discussions that arose. It also documents the take-aways of a Post-Drought Operations Review meeting that took place on November 3, 2023, and a subsequent meeting of the CO-OP Operations Committee on November 17.
