NYC Drinking Water Supply Map

The Croton, Catskill and Delaware watersheds deliver approximately 1.4 billion gallons of pristine, unfiltered drinking water each day from 19 upstate reservoirs to more than nine million people living in New York City, Westchester, Putnam, Orange and Ulster Counties.
