The Croton River ( / ˈ k r oʊ t ən / KROH -tən ) is a river in southern New York with three principal tributaries: the West Branch , Middle Branch , and East Branch . Their waters, all part of the New York City water supply system , join downstream from the Croton Falls Reservoir . Together, their waters and the reservoirs linked to them represent the northern half of the New York City water system's Croton Watershed .
12-965: Shortly after the confluence of the three Croton River branches the Croton River proper, along with its tributary, the Muscoot River , flows into the Muscoot Reservoir , after which it empties into the New Croton Reservoir , which feeds the New Croton Aqueduct supplying water to New York City . Excess water leaves the spillway at the New Croton Dam and empties into the Hudson River at Croton-on-Hudson, New York at Croton Point , about 30 miles (50 km) north of New York City. The river has
24-588: A drainage basin of 20 square miles (52 square kilometres). Water which is either released or spilled out of Amawalk Reservoir flows south in the Muscoot River and eventually enters the Muscoot Reservoir , and then flows into the New Croton Reservoir . The water enters the New Croton Aqueduct , which sends water to the Jerome Park Reservoir in the Bronx , where the water is distributed to

60-547: A watershed area of 361 square miles (930 km). The Croton River was the main source of the city water supply from 1842 to the mid-20th century. Water was brought to the city through the Croton Aqueduct , later called the Old Croton Aqueduct. The larger New Croton Aqueduct opened in 1890. The Old Croton Aqueduct remained in service until 1955. Seeking to expand the city's water supply, engineers of

The rivers headwaters flow southwards from gates at Kirk Lake , a controlled lake in the New York City water supply system , and Lake Mahopac , lying near one-another in the Putnam County hamlet of Mahopac, New York in the Town of Carmel . About two miles south the flow of Secor Brook joins in, an outfall from Lake Secor to
84-704: The Croton system as it became more and more unsuitable for drinking. In 2004, a project was started to rehabilitate the New Croton Aqueduct and build the Croton Water Filtration Plant , which came online in May 2015. By the early 21st century the Croton system was supplying 10% of the city's water. 41°11′12″N 73°52′36″W / 41.18667°N 73.87667°W / 41.18667; -73.87667 This article related to
96-497: The Croton were dammed, creating the Croton Falls Reservoir , which was placed into service in 1911. In the 1890s, rather than building an expensive filtration system , the city ordered the destruction or relocation of any village or hamlet in the watershed that was considered to be a potential pollution source for the Croton or its tributaries. Many were moved. In the late 1990s, the city stopped using water from
108-408: 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) watershed, would hold 14.2 billion US gallons (54,000,000 m) at full capacity. This dam, now known as the New Croton Dam , was completed in 1906. Further upstream, two tributaries of
120-676: The northwest. After trending slightly southeast for a bit over three miles the Muscoot drains into the Amawalk Reservoir in the town of Somers , crossing about midway along its length into Westchester County. Upon leaving the Amawalk Reservoir via a spillway in the Amawalk Dam at the reservoir's southern end, the Muscoot is shortly joined by Hallocks Mill Brook from the west. Less than two miles later it flows into
132-642: The northwestern reaches of the Muscoot Reservoir west of Whitehall Corners and northwest of Katonah, New York . The waters of Muscoot Reservoir then join with those of the New Croton Reservoir before either being carried to New York City via the New Croton Aqueduct or, in times of surplus, over the spillway at the New Croton Dam and into the Croton River , then carried into the Hudson River at Croton-on-Hudson at Croton Point about 30 miles (50 km) north of New York City. 41°16′10″N 73°43′31″W / 41.2695°N 73.7254°W / 41.2695; -73.7254 This article related to

#1732772824729144-597: The system's Croton Watershed , it was formed by impounding the middle of the Muscoot River, one of the tributaries of the Croton River . This reservoir was put into service in 1897, and was named after the original community of Amawalk, New York , which was inundated by the reservoir and relocated near the dam. The reservoir is one of the smaller in NYC's water supply system. It is only about 3 miles (4.8 kilometres) long. It only holds about 6.7 billion US gal (25 million m ) of water at full capacity, and has
