 During drought periods the West Branch also receives water pumped in from the Hudson River by the City's Chelsea Pumping Station near Beacon in Dutchess County, some from New York City.It was used for this purpose during the 1965–66 and 1985 droughts, as well as during May 1989.Water withdrawn from the West Branch ordinarily flows via the Delaware Aqueduct to the Kensico Reservoir in Westchester County for further settling.
