New York City’s main source of drinking water – an interconnected series of reservoirs
covering almost 2,000 square miles across parts of eight New York counties and Fairfield
County, Connecticut – is an invaluable resource. Protecting the watershed is a high
priority for many government agencies and private organizations. We hope the links
below will help you learn more about the importance of protecting the watershed
and how you can help. These resources are part of an ongoing effort on behalf of
the Open Accessible Space Information System (OASIS NYC) to provide information
to the thousands of people who visit the OASIS website each week to better understand
their neighborhoods and the stewardship and sustainability of the city’s open space
