The reservoir is the collecting point for the water from all six reservoirs in the Catskill Mountains: the Ashokan Reservoir, the Cannonsville Reservoir, the Neversink Reservoir, the Pepacton Reservoir, the Rondout Reservoir, and the Schoharie Reservoir.
It also receives water from the Croton Falls Reservoir, the Muscoot Reservoir, the New Croton Reservoir, and the West Branch Reservoir through the Catskill and Delaware aqueducts, along with water from Rye Lake.

The resulting body of water has a drainage basin of only 13 square miles (34 km²), and holds 30.6 billion US gallons (116,000,000 m³) of water at full capacity.
The reservoir itself provides only 2% of NYC's water supply; the rest of the water comes from the reservoirs to which it connects.
The water in the reservoir either provides NYC with water, or it travels down the spillway at the southernmost dam, and continues down the rest of the Bronx River, eventually flowing to the East River.

The water that does supply New York City travels down either the Catskill Aqueduct or the Delaware Aqueduct.
If it goes down the Delaware Aqueduct, it will pass through Yonkers, and flow through the Hillview Reservoir.
It then continues through The Bronx, Manhattan, Brooklyn, and then stops at Staten Island.
If it flows through the Catskill Aqueduct, It will stop at the Hillview Reservoir, and continue on through The Bronx, Queens, Brooklyn, and then stop at Staten Island.
