The Catskill Aqueduct is a crucial water supply system that transports drinking water from the Catskill Mountains to New York City. Completed in 1917, it spans approximately 85 miles and is part of the larger New York City water supply system. The aqueduct primarily channels water from the Ashokan Reservoir to the Croton Reservoir. Constructed using a combination of tunnels and open channels, the aqueduct helps provide clean water to millions of residents. It plays a vital role in maintaining the city's water quality and ensuring a reliable supply, making it an essential infrastructure component for urban living.
