A simple water budget includes precipitation, streamflow, change in storage, evapotranspiration, and residuals: P=Q + ET + ΔS + e. It is essential to include the managed component (i.e., the “human” component) to close the water budget and reduce the magnitude of the residuals from “natural” water budgets. Some of the largest components of managed water withdraws are public supply, irrigation, and thermoelectric. The modified water budget is: P=Q + ET + ΔS + (PS + Irr + TE) + e, where PS is public supply, Irr is irrigation, and TE is thermoelectric water use. This data release contains both the natural and managed components of the water budget for a region within the Apalachicola-Chattahoochee-Flint (ACF) River...

Background For effective wellhead protection, the area where water carrying potential contaminants can enter the groundwater system and flow to the supply well must first be defined, and then best management practices need to be implemented to minimize the opportunity for contamination to occur in areas defined as sources of water to the well. Determination of the sources of water and contributing areas to wells is complex because aquifers and their connection with recharge sources are heterogeneous in nature and hidden from direct observation. The major groundwater source for public supplies in upstate New York are valley-fill aquifers of glacial and post-glacial origin. Saturated coarse-grained sediments (sand...

Problem - The demand for water in New York State is unevenly distributed. Because increasing competition for local supplies could lead to shortages, it is expedient to know how and where water is withdrawn, delivered, and used. There are many dimensions to water-use issues, and all should be considered to develop a full understanding of the use and delivery of water in the State. In order to apply water-use information to problems of water-demand management, many data elements need to be collected and stored in a convenient location and format. The categories of water use most commonly considered include public-water supply, domestic, thermoelectric power generation, industrial, irrigation and, to a lesser degree,...

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...

Background The Shinnecock Nation is located on the south fork of eastern Long Island adjacent to the town of Southampton to the east, and the hamlet of Shinnecock Hills to the west, in Suffolk County, NY. Shinnecock Nation tribal lands encompass approximately 1.2 square miles and are bounded to the east and west by tidal creeks, and to the south by Shinnecock Bay. The Shinnecock Nation has a population of 662 residents who live in 256 housing units (U.S. Census, 2016). The Shinnecock Nation became the 565th federally recognized Tribe by the United States government in October 2010. (Shinnecock Nation, 2014). Shinnecock Nation tribal lands are situated in a coastal environment where bay and wetland health 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...

The lakes, rivers, and streams of New York State provide an essential water resource for the State. The information provided by time series hydrologic data is essential to understanding ways to promote healthy instream ecology and to strengthen the scientific basis for sound water management decision making in New York. The U.S. Geological Survey, in cooperation with The Nature Conservancy and the New York State Energy Research and Development Authority, has developed the New York Streamflow Estimation Tool to estimate a daily mean hydrograph for the period from October 1, 1960, to September 30, 2010, at ungaged locations across the State. The New York Streamflow Estimation Tool produces a complete estimated daily...
