The south outlet of the Shandaken Tunnel, just above
Esopus Creek.
The Shandaken Tunnel is an underground tunnel in Eastern New York State, and is part of the New York City Water Supply System. It was constructed from 1917 to 1924. The aqueduct starts in Gilboa, New York at the Schoharie Reservoir, which is in the counties of Schoharie, Delaware, and Greene. The water flows south towards the Esopus Creek in Ulster County. It finally empties into a man-made pool in Allaben, New York, within the Township of Shandaken, and enters Esopus Creek there.
The tunnel is over 18 miles (29 kilometres) in length, and carries water through Greene County and Ulster County. Water is forced through the tunnel by gravity; it slowly declines at a rate of 4.4 feet per mile. It is 11.5 feet high, and 10.2 feet wide, meaning that it isn't a perfect circle. There are seven shafts throughout the length of the tunnel, all serving as air vents to introduce oxygen to the water, and to bring out impurities.
