![]() NPS Nearly 18 million people rely on the Delaware River system for water. The main stem of the Delaware extends 330 miles from the confluence of its East and West branches near the Catskill Mountain town of Hancock, NY to the mouth of the Delaware Bay. In all, the basin comprises 13,539 square miles, draining parts of Pennsylvania, New Jersey, New York and Delaware. In order to monitor the water quality of the river basin, water samples must be collected and analyzed. A segment of those collection and analysis responsibilities falls to school children involved in the annual Water Snapshot program.
