The West Branch Delaware River is one of two branches that form the Delaware River. It is approximately 90 mi (144 km) long, and flows through the U.S. states of New York and Pennsylvania. It winds through a mountainous area of New York in the western Catskill Mountains for most of its course, before joining the East Branch along the northeast border of Pennsylvania with New York. Midway or so it is empounded by the Cannonsville Dam to form the Cannonsville Reservoir, both part of the New York City water supply system for delivering drinking water to the City.
The Croton Aqueduct or Old Croton Aqueduct was a large and complex water distribution system constructed for New York City between 1837 and 1842. The great aqueducts, which were among the first in the United States, carried water by gravity 41 miles (66 km) from the Croton River in Westchester County to reservoirs in Manhattan. It was built because local water resources had become polluted and inadequate for the growing population of the city. Although the aqueduct was largely superseded by the New Croton Aqueduct, which was built in 1890, the Old Croton Aqueduct remained in service until 1955.
The West Canada Creek is a 76-mile-long (122 km) river in upstate New York, United States. West Canada Creek is an important water way in Hamilton, Oneida, and Herkimer counties, draining the south part of the Adirondack Mountains before emptying into the Mohawk River near the Village of Herkimer. The name "Canada" is derived from an Iroquoian word for "village" (Kanata).
Esopus Creek is a 65.4-mile-long (105.3 km) tributary of the Hudson River that drains the east-central Catskill Mountains in the U.S. state of New York.

Many tributaries extend its watershed into neighboring Greene County and a small portion of Delaware County. Midway along its length, it is impounded at Olive Bridge to create Ashokan Reservoir, the first of several built in the Catskills as part of New York City's water supply system. Its own flow is supplemented 13 miles (21 km) above the reservoir by the Shandaken Tunnel, which carries water from the city's Schoharie Reservoir into the creek.
