Background Every day, the New York City Department of Environmental Protection (DEP) supplies more than one billion gallons of drinking water to more than nine million people. To do this, the DEP maintains an extensive network of reservoirs and aqueducts. A major part of this system, the West of Hudson (WOH) network, in the Delaware and Hudson River drainages, includes six reservoirs (fig. 1) – Ashokan, Cannonsville, Neversink, Pepacton, Rondout, and Schoharie – which were constructed from the early 1900s to the 1960s and have an estimated combined storage capacity of more than 460 billion gallons. Problem and Objective The daily and seasonal management of the WOH reservoirs by DEP depends on accurate bathymetric...

Problem Statement More than nine million people rely on the New York City Water-Supply System for their daily-drinking water needs. Approximately 40 percent of this water comes from the Schoharie and Ashokan Reservoirs (fig. 1). This water is transported from the Catskill Area to New York City through Esopus Creek and a series of man-made tunnels and aqueducts built starting in the early 1900s (fig. 1). The U.S. Geological Survey (USGS) has been measuring streamflow continuously in the Upper and Lower Esopus Creeks for many decades. Specifically, streamflow has been measured in the Upper Esopus Creek at Coldbrook (station number 01362500) for about 80 years and in the Lower Esopus Creek at Mount Marion (station...
