As a part of the New York City Public Art Fund, The New York City Waterfalls are on display from 06.26-10.13.2008. The four waterfalls are the collaborative work of artist Olafur Eilasson. They are are built on scaffolding, a common place on the streets of NY, and range in height from 90-120'-0". Fear not fellow environmentalists, the water from the East River (which is actually not a river at all, but a Straight) with protective pools to prevent aquatic life from being hurt, they are 100% green power, and are not filtered out in any way.
Eilasson says that the water is a direct reflection of NYC and address the heightened relationship with the environment. The water changes, as does the city.
