Welcome to the Watershed!

The Catskill Watershed Corporation (CWC) is a locally based and locally staffed non-profit Local Development Corporation responsible for several environmental protection, economic development, and education programs in the New York City Watershed West of the Hudson River.

CWC’s dual mission is to preserve and strengthen the region’s economy as well as to administer a host of Watershed Protection Programs to protect the water supply for half the population of the state of New York. 90% of New York City’s water supply is unfiltered from the West of Hudson Watershed.

Our environmental protection, economic development and education programs are administered in 41 towns that lie wholly or partially within the NYC Catskill-Delaware Watershed region which supplies water to five upstate counties and 9.5 million people in New York State.

Recreational Boating

Four of the Catskill Region’s six New York City Water Supply reservoirs — Cannonsville, Neversink, Pepacton and Schoharie – are open to non-motorized recreational boating.

The Catskill Watershed Corporation and the NYC Department of Environmental Protection sponsor the NYC Reservoir Recreational Boating Program.

Canoes, kayaks, sculls and row boats are welcome to put in at any of 16 launch sites, as long as they have been steam cleaned and tagged by authorized vendors before entering each reservoir. LEARN MORE
