The Amawalk Reservoir was formed by impounding the middle of the
Muscoot River, one of the tributaries of the
Croton River, and put into service in 1897. The reservoir has a
drainage basin of . About long and narrow, it holds about of water at full capacity, making it one of the smaller in NYC's water supply system. Water either released or spilled out of Amawalk flows south in the Muscoot River to its confluence with the
Muscoot Reservoir, a collecting point for the Amawalk,
Titicus, and
Cross River Reservoirs. The Muscoot flows into the
New Croton Reservoir, where the
New Croton Aqueduct carries the Croton Watershed water to the
Jerome Park Reservoir in the
Bronx for distribution to the Bronx and northern
Manhattan. On average, the New Croton Aqueduct delivers 10% of New York City's drinking water. Excess passing over the New Croton Dam spillway flows back into the Croton River and drains into the
Hudson River at
Croton Point. ==See also==
