The Catskill Aqueduct begins at the Ashokan Reservoir in Olivebridge, New York, in Ulster County. The Ashokan Reservoir is a reservoir in Ulster County, New York, USA. Olivebridge, New York is a community in Ulster County, New York, U Ulster County is a County located in the state of New York, USA. It then heads south, flowing toward Orange County, New York, and then crosses underneath the Hudson River to Putnam County, New York. Orange County is a County located in the US state of New York. The Hudson River, called Muh-he-kun-ne-tuk, the Great Mohegan by the Iroquois, or as the Lenape Native Americans called it in Unami Putnam County is a County located in the US state of New York, in the lower Hudson Valley. The aqueduct transports water from Ashokan as well as the Schoharie Reservoir, which feeds into Ashokan. An aqueduct is an artificial channel that is constructed to convey water from one location to another From the Ashokan, the aqueduct traverses in a southeasterly direction through Ulster, Orange, and Putnam, counties. It crosses 1100 feet below the Hudson River bed at Storm King Mountain in Orange county. It crosses into Putnam county on the east side of the river at Breakneck Mountain. [1]
It then enters Westchester County, New York, and flows to the Kensico Reservoir, which also receives water from the City's Delaware Aqueduct. Westchester County is a primarily Suburban county located in the U The Kensico Reservoir is a Reservoir located in Valhalla New York that was put into service in 1915 Roebling's Delaware Aqueduct, also known as the Delaware Aqueduct is the oldest existing wire Suspension bridge in the United States; it runs It continues from the Kensico reservoir and terminates at the Hillview Reservoir in Yonkers. The Hillview Reservoir is a 164 Acre (066 km² storage Reservoir in southeastern Yonkers New York. Yonkers is the fourth largest city in the US State of New York (behind Rochester, Buffalo, and New York City) and the largest city in The Hillview Reservoir then feeds City Tunnels 1 and 2, which bring water to New York City. If necessary, water can be made to bypass both reservoirs.
Construction commenced in 1907. The aqueduct proper was completed in 1916 and the entire Catskill Aqueduct system including three dams, and 67 shafts was completed in 1924. [2]The total cost of the aqueduct system was $177 million. [3]
The 163 mile aqueduct consists of 55 miles of cut and cover aqueduct, over 28 miles of grade tunnel, 35 miles of pressure tunnel, six miles of steel siphon, and 39 miles of conduit. A tunnel is an underground passageway The definition of what constitutes a tunnel is not universally agreed upon The 67 shafts sunk for various purposes vary in depth from 174 to 1187 feet. [4] Water flows by gravity through the aqueduct at a rate of about 4 feet per second. [5]
The Catskill Aqueduct has an operational capacity of about 550 million gallons per day north of the Kensico Reservoir in Valhalla, New York. The Kensico Reservoir is a Reservoir located in Valhalla New York that was put into service in 1915 Valhalla is a hamlet and census-designated place (CDP located in the town of Mount Pleasant in Westchester County New York, Capacity in the section of the aqueduct south of Kensico Reservoir to the Hillview Reservoir in Yonkers, New York is 880 million gallons per day. The Hillview Reservoir is a 164 Acre (066 km² storage Reservoir in southeastern Yonkers New York. Yonkers is the fourth largest city in the US State of New York (behind Rochester, Buffalo, and New York City) and the largest city in [6] The aqueduct normally operates well below capacity with daily averages around 350 - 400 million gallons of water per day.
