PROBLEM As part of an effort to sustain a viable water-supply system for 8 million residents in New York City, and 1 million other residents in upstate New York that rely on City water, the New York City Department of Environmental Protection (NYCDEP) has requested a multi-disciplinary study by the U.S. Geological Survey (USGS) to determine the source(s) of water to surface-water sites (springs and expressions) in areas adjacent to the Catskill Aqueduct. In the area near the Delaware Aqueduct, which has been determined by the USGS to have a water-tunnel contribution to flooding issues during periods of high precipitation, the NYCDEP plans to repair the leaks with a grouting procedure. However, without monitoring...

Problem Previous hydrologic studies have indicated that there may be sufficient water resources underlying Queens, Kings, Richmond, New York, and Bronx Counties for use as a supplemental water supply in times of drought or other emergency. An extensive ground-water and surface-water monitoring program is necessary to provide a comprehensive hydrologic data set for use in ongoing and future ground-water investigations. Objective The project will provide a continuous hydrologic data set needed for resource assessment, planning, and protection. To meet this objective the U.S. Geological Survey (USGS), in cooperation with the New York City Department of Environmental Protection, maintains and operates a network of approximately...

Background The Ashokan Reservoir is located in the Catskill Mountains of New York State and is part of New York City’s (NYC) water supply system. The NYC water-supply system is operated by the NYC Department of Environmental Protection (NYCDEP) under a filtration avoidance determination (FAD) issued by the New York State Department of Health. The Ashokan Reservoir watershed is 255 mi2 and is one of two reservoirs in the New York City Catskill Reservoir system and one of six reservoirs in the West-of-Hudson Catskill-Delaware system. The upper Esopus Creek is the primary tributary to the Ashokan Reservoir, with a 192 mi2 watershed from the source, Winnisook Lake, to the Ashokan Reservoir near Boiceville, NY. Suspended-sediment...

Problem Suspended-sediment concentration (SSC) and turbidity are primary water-quality concerns in New York City’s (NYC) water-supply system (U.S. Environmental Protection Agency, 2007). In the NYC water-supply system turbidity is largely caused by clay and silt rather than organic material (Effler et al. 1998, Peng et al. 2002, 2004). Sediment can originate from the watershed land surface and the active stream corridor (the stream bed and its adjacent banks and hillslopes) (Walling 2005). In the upper Esopus Creek watershed, the main source of water to the Ashokan Reservoir, the active stream corridor is the primary source of sediment and turbidity to the stream. Terrestrial sources of sediment and turbidity are...

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...

Problem Previous hydrologic studies have indicated that there may be sufficient water resources underlying Richmond, New York, and Bronx Counties for use as a supplemental water supply by the New York City Department of Environmental Protection (NYCDEP) in times of a drought or other water shortage. Unfortunately, comprehensive data on the quantity and quality of the Counties' water resources are not available to make an accurate assessment. In order to evaluate the availability and suitability of these resources, representative and timely data on the ground-water and surface-water resources of these three Counties are needed. Objectives The primary objective is to develop, operate, and maintain long-term monitoring...
