The Delaware Aqueduct, completed in 1945, taps tributaries of the Delaware River in the western Catskill Mountains and provides approximately half of New York City's water supply. [16] The latter two aqueducts provide 90% of New York City's drinking water, and the watershed for these aqueducts extends a combined 1 million acres (400,000 ha).
NYCDEP manages three upstate supply systems to provide the city's drinking water: the Croton system, the Catskill system, and the Delaware system. The overall distribution system has a storage capacity of 550 billion US gallons (2.1 × 10 9 m 3) and provides over 1 billion US gallons (3,800,000 m 3) per day of water to more than eight million city residents and another one million users in ...
The aqueduct normally operates well below capacity with daily averages around 350–400 million US gallons (1,500,000 m 3) of water per day. About 40% of New York City's water supply flows through the Catskill Aqueduct.
The process of linking agriculture with the city's urban markets has been largely built upon the fact that the city water supply comes from the protected watersheds in Upstate New York. The water supply system, the largest surface storage and supply complex in the world, yields over 1 billion US gallons (3,800,000 m 3 ) of water daily, from ...
The aqueduct was constructed between 1939 and 1945, and carries approximately half of New York City's water supply of 1.3 billion US gallons (4,900,000 m 3) per day. At 13.5 feet (4.1 m) wide and 85 miles (137 km) long, the Delaware Aqueduct is the world's longest tunnel. [1]
The Croton Watershed is a term describing a part of the New York City water supply system. It is not synonymous with the biological feature Croton River watershed . Numerous small natural lakes and ponds, as well as large Lake Mahopac , are within the river's watershed but not part of the NYC water supply system (even though they too ultimately ...
Rondout Reservoir is part of New York City's water supply network. It is located 75 miles (121 km) northwest of the city in the Catskill Mountains, near the southern end of Catskill Park, split between the towns of Wawarsing in Ulster County and Neversink in Sullivan County. It is the central collection point for the city's Delaware System ...
Seeking to expand the city's water supply, engineers of the city Aqueduct Commission designed in 1884 a 275-to-300-foot-high (84 to 91 m) masonry dam spanning the Croton River near its mouth. The resulting storage reservoir, impounding a 16-square-mile (41 km 2 ) watershed, would hold 14.2 billion US gallons (54,000,000 m 3 ) at full capacity ...
