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 billion US gal of water. In the 1850's, Nicholas Dean, the board president of the Croton Aqueduct water distribution system, proposed that Central Park be planned around its existing receiving reservoir.
