About NYC Reservoir Levels

New York City's water supply system is one of the largest surface water supply systems in the world, serving over 8.3 million residents plus an additional 1 million in upstate communities. The system relies on a network of 19 reservoirs and three controlled lakes, with a total storage capacity of approximately 580 billion gallons.

The three main watershed systems — Croton, Catskill, and Delaware — deliver an average of 1 billion gallons of water per day to New York City. The Catskill and Delaware systems, located in the Catskill Mountains, provide about 90% of the city's supply through one of the world's largest unfiltered water systems.

Key reservoirs include Ashokan Reservoir, Pepacton Reservoir, Cannonsville Reservoir, and Rondout Reservoir. The NYC Department of Environmental Protection monitors these levels closely, especially during dry summers when consumption increases and drought watch protocols may be activated.

Is there a drought risk for NYC water supply?
