New York City Watershed


The NYC Watershed is located in the Catskill Mountains of New York State. The water is provided by precipitation (rain & snow) that falls within the Watershed, flows to nearby streams, and then is collected within the reservoirs. The reservoirs and their major tributaries within the NYC Watershed, including those within Delaware County, are monitored continuously for quality and quantity. For more detailed information about the NYC Watershed, please visit the Facts about the NYC Watershed page.
