This U.S. Geological Survey data release provides surface-water quality, streamflow, and groundwater-elevation data collected within the Central Pine Barrens (CPB) Region of Suffolk County, New York. The data were collected in cooperation with the Central Pine Barrens Commission and the Town of Brookhaven as part of a five-year comprehensive water-resources monitoring program. Water quality and quality-assurance data from seven sites on two rivers (Carmans River- 5 sites and Peconic River - 2 sites) in the CPB are included. Carmans River sites were sampled four times throughout the year (fall, winter, spring, and summer) and Peconic River sites were sampled twice throughout the year (fall and spring). Water-quality...

Problem: Dissolved volatile-organic compounds (VOCs), including trichloroethylene (TCE), have been identified in a sole-source aquifer near the former Northrop Grumman Bethpage facility and Naval Weapons Industrial Reserve Plant (NWIRP) in Nassau County, N.Y. The Northrop Grumman Bethpage facility and NWIRP are listed as Class II inactive hazardous waste disposal sites (Site Nos. HW130003A and HW130003B respectively) on the New York State registry of Inactive Hazardous Waste Disposal Sites. Past investigations have documented that the groundwater contamination originated from these two sites and now extends nearly four miles to the south; in the direction of groundwater flow. During 2019, a groundwater-flow model...

From 2013 to 2018, the U.S. Geological Survey, in cooperation with the Town of Enfield and the Tompkins County Planning Department, studied the unconsolidated aquifers in the Enfield Creek Valley in the town of Enfield, Tompkins County, New York. The objective of this study was to characterize the geohydrology and water quality of the unconsolidated aquifers in the Enfield Creek valley and produce a summary report of the findings. The spatial extent and geohydrologic framework of these unconsolidated aquifers were delineated using existing data, including soils maps, well records, geologic logs, topographic data, and published reports. An interactive ArcGIS Online web map of the geospatial datasets is available...

This U.S. Geological Survey (USGS) data release contains batch formatted annual peak streamflow data (PkFlows_AllSites.txt) for the respective periods of record (through the 2020 or 2021 water year) for seven USGS streamgages in the upper Esopus Creek watershed in upstate New York. This data release also contains batch formatted specification (PkFlows_AllSites.psf) and output (PEAKFLOWS_ALLSITES.PRT) files from log-Pearson type III (LPIII) flood-frequency analysis of the annual peak streamflow data from version 7.3 of the USGS PeakFQ software (https://water.usgs.gov/software/PeakFQ/), and a csv file (FloodFrequencyEstimates.csv) with estimates of flood magnitudes for selected annual exceedance probabilities from...

Problem - During 2003-07, a precipitation-runoff watershed model with water-quality components was developed to assess pollutant sources and loadings to Onondaga Lake, and to assist water-resources managers in making decisions regarding the selection and location of mitigative measures to maximize load reduction for a given effort. In the absence of chemical loading rates that were specific to the Onondaga Lake Basin, the model was calibrated to estimated loading rates that were derived from a review of scientific literature. During 2005-08, an intensive water-quality study of the basin was conducted to provide basin-specific data that, among other uses, could be incorporated into the watershed model and provide...

Objective: The USGS New York Water Science Center (NYWSC) works with other Federal agencies as well as with State, municipal, and tribal agencies to provide research and data about water-related issues. Relevance and Impact: The NYWSC leads the scientific and water-resources management communities by providing high-quality, timely, and unbiased scientific data, reports, and other information that are widely accessible and understandable and that benefit science interests of all levels of government, academia, nongovernmental organizations, the private sector, and the general public. Statement of Problem: The NYWSC studies the effects of weather, climate, and manmade influences on groundwater levels, streamflow (discharge),...

Problem The ground-water flow system underlying the Manhasset Neck Peninsula, which provides potable water to the local population, consists of a complex assemblage of Pleistocene- and Cretaceous-age sediments that form five aquifers and at least two confining units. Recent hydrogeologic mapping in Manhasset Neck indicates significant glacial erosion of the Magothy aquifer, Raritan Clay, and Lloyd aquifer, and several gaps in the confining units that overlie the North Shore and Lloyd aquifers. Five areas of salt-water intrusion have been delineated, two of which are considered active. Several public-supply wells on the Manhasset Neck Peninsula have been shut down in the past as a result of saltwater intrusion....

The upper Esopus Creek is the primary tributary to the Ashokan Reservoir, part of the New York City (NYC) water supply system. Suspended-sediment concentration (ssc) and turbidity are primary water-quality concerns in the NYC water-supply system, particularly in the upper Esopus Creek watershed. In 2016 the NYC Department of Environmental Protection and U.S. Geological Survey entered into a collaborative agreement to conduct a comprehensive study of suspended sediment and turbidity in the upper Esopus Creek watershed. Objectives included ssc, streamflow, and turbidity monitoring, and development of turbidity-ssc regression equations to estimate ssc from continuous turbidity measurements. Cross-section and point...

This data release contains the output from a Soil-Water-Balance (SWB) model (Westenbroek and others, 2010), used to estimate potential recharge to the Long Island regional aquifer system from 1900-2019. Output data for two SWB simulations are included. The first simulation uses available land-use/land-cover datasets to estimate recharge with changing land use from 1900-2019 (referred to as the post-development simulation). The second simulation assumed a forested, undeveloped (predevelopment simulation) condition across Long Island for the same period. The same soil coverages and time-series climate data were used throughout both simulations. Potential recharge was spatially distributed as gridded output across...

This data release contains results of a high-water mark survey across Upstate New York following flash flooding during July 9-10, 2023. The survey was conducted between July 12 and September 20, 2023 by U.S. Geological Survey (USGS) personnel, and is based on surveyed elevations of mud, debris, and seed lines (Koenig and others, 2016) left by the flooding. Real-time and static Global Navigation Satellite System (GNSS) surveying (Rydlund and Densmore, 2012), combined with differential leveling (Kenney, 2010), were used to determine high-water mark elevations at 186 locations. Additional data associated with the July 2023 flooding, such as photos of the survey locations, can be found in the USGS Flood Event Viewer,...

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...
