"The New York City Waterfalls" is a public art project of four man-made waterfalls rising from New York Harbor, some as high as the Statue of Liberty. Organized by the nonprofit Public Art Fund and the city of New York, the artist Olafur Eliasson's much-publicized initiative cost $15 million. It will appear from June 26 to Oct. 13 and run from 7 a.m. to 10 p.m. City officials and the Public Art Fund say that no city money is being used to pay for the waterfalls, with all of the funds coming from foundations, corporations and private supporters.
