It is located about two hours away from Manhattan and is responsible for 40% of New York’s water supply; Ashokan Reservoir. It travels more than 100 miles of tunnels from this location to provide water to 8.4 million residents of the city. The Catskill Aqueduct that delivers water from Schoharie and Ashokan reservoirs is operational since 1915.
Recently, New York Public Library released about 200,000 digitized images and they also include the pictures of Catskill Aqueduct during the construction (1906-1915).
