The Jacqueline Kennedy Onassis Reservoir, also known as Central Park Reservoir, is a decommissioned reservoir in Central Park in the borough of Manhattan, New York City, stretching from 86th to 96th Streets. It covers 106 acres and holds over 1,000,000,000 US gallons of water.
Croton Aqueduct Board president Nicholas Dean proposed the construction of Central Park around its receiving reservoir in the 1850s. As part of this project, the Central Park Reservoir was completed in 1862. The reservoir was decommissioned in 1993, after it was deemed obsolete, and control was transferred to the Department of Parks and Recreation in 1999. The Central Park Reservoir was renamed in honor of Jacqueline Kennedy Onassis in 1994 to commemorate her contributions to the city, and because she lived nearby.
