Rejuvenating Central Park - As new York's Central Park approached its 150th birthday, water quality specialists looked for ways to keep its waters healthy

摘要

When strolling through the Ramble, bird-watching by the Lock, or boating on the Lake, it is easy to forget that Central Park is surrounded by the most densely populated metropolitan area in the United States. However, accommodating 20 million pedestrians and millions of vehicles each year, as we as the surrounding metropolis of 4 million residents takes its toll on this oasis - and on anyone charged with developing an integrated water resource management plan for the park. Central Park's eight man-made waterbodies - the Reservoir, the Lake, Harlem Meer, the Pond, Turtle Pond, the Pool, Conservatory Water, and the Loch - cover 60.7 ha (150 ac; more than 15 percent of the park's total area) and are an integral part of the visitor experience (see Figure 1, p. 52). They provide visitors with opportunities for boating, fishing, and other "secondary contact" recreational activities.
