  The city's active reservoirs, like Jerome Park Reservoir in the Bronx and Silver Lake Reservoir on Staten Island, are easy to spot.
  But there are quite a few city spaces that you may be surprised to learn once functioned as reservoirs.
  Beginning in the 1840s, what is now the Great Lawn in Central Park was a receiving reservoir for clean water from the Croton Reservoir in Westchester. (It was replaced by the Central Park Reservoir, which was decommissioned in the 1990s.)
  In the 1880s, the Williamsbridge Oval was transformed into a reservoir to carry water from the Bronx and Byram Rivers to parts of the Bronx from the Kensico Reservoir in Valhalla. (It was decommissioned some 30 years later.)
  In the 1890s, what we now know as the New York Public Library on 42nd Street was a distributing reservoir called the Murray Hill Reservoir. (Bryant Park was then called Reservoir Square.) And Baisley Pond in Jamaica, Queens, was part of Brooklyn Waterworks, a group of reservoirs and wells that supplied water to the Ridgewood Reservoir.
  In fact, about 80 percent of the ponds and lakes in our city parks were once used as reservoirs or impoundments.
