New York Water Science Center
Data and Tools
Continuous and discrete surface-water, groundwater, and water-quality data are collected to provide long-term hydrologic records critical to investigating hydrology, modeling climate-change, evaluating natural and anthropogenic changes in the hydrologic regime, and providing information on water availability to water managers.
USGS StreamStats
StreamStats is a Web-based Geographic Information Systems (GIS) application that provides users with access to an assortment of analytical tools that are useful for a variety of water-resources planning and management purposes.

New York Water Data
Emerging contaminant data at wastewater treatment facilities, municipal water supplies, surface water and lake sites in the northeastern United States, 2009-2018
Over 300 samples were collected in New York, Vermont, and Massachusetts from wastewater treatment facilities (20 locations), drinking water facilities (9 locations), streams (53 locations), lakes (2 locations), a bay (1 location), and a POCIS (Polar Organic Chemical Integrative Sampler) blank sample between April 2009 and October 2018. This data release provides chemistry data for over 400...
NY WSC Go2 Mapper
Interactive web mapping application used to display Go2 warning messages and field personnel locations. The Go2 system is used by USGS staff to monitor the maintenance of USGS gages.
Drought Streamflow Probabilities in Northeast Region
Maximum likelihood logistic regression (MLLR) is used to estimate drought probabilities for selected Northeast rivers and streams. Winter streamflows are used to estimate the chance of hydrologic drought during summer months. This application allows the display and query of these drought streamflow probabilities for Northeastern streams.
Detailed Aquifer Mapping Program in Upstate New York
Define the hydrogeology of extensively used (primary) stratified-drift aquifers in upstate NY, and present the information as individual sets of maps at 1:24,000 scale. Each published report describes the hydrogeology of a specific aquifer or segment, and depicts selected hydrogeologic characteristics. Continue the hydrogeologic assessment and mapping of selected principal aquifers in upstate...
Baselines used to calculate rate of shoreline change statistics for New York State coastal wetlands
This data set contains baselines used to calculate shoreline rate of change statistics for New York State coastal wetlands. Analysis was performed in ArcMap 10.5.1 using the Digital Shoreline Analysis System (DSAS), created by U.S. Geological Survey, version 5.0, and polyline vector historical shorelines from the National Oceanic and Atmospheric Administration (NOAA) . The baselines used in...
Intersection points used to calculate rate of shoreline change statistics for New York State coastal wetlands
This data set contains intersection points used to compute rate of change statistics for New York State coastal wetlands. Analysis was performed in ArcMap 10.5.1 using historical vector shoreline data from the National Oceanic and Atmospheric Administration (NOAA). Rate of change statistics were calculated using the Digital Shoreline Analysis System (DSAS), created by U.S. Geological Survey...
Data for Assessing the Status of Macroinvertebrate Communities and Sediment Toxicity in the Buffalo River Area of Concern, New York
Data from 10-day sediment toxicity tests of bed sediments from the Buffalo River Area of Concern (AOC) and reference reaches on the Buffalo River upstream of the AOC, Erie County, New York, respectively. Specifically, the data was used to compare the survival and growth of two macroinvertebrate species in sediments from study sites and laboratory controls. Results are from 10-day sediment...
Adirondack and Catskill stream-fish survey dataset (ver. 2.0, July 2019)
The dataset is composed of two data tables containing information from electrofishing surveys conducted in the Catskill and Adirondack regions. The first data table contains fish collection information and the second data table contains information on the sampled reaches. First posted September 25, 2018, ver. 1.0 Revised July 2019, ver. 2.0 Version 2.0: This version of the dataset has...
2018 Hydrologic Data Summary for the Central Pine Barrens Region, Suffolk County, New York
This document provides a summary of surface water-quality, streamflow, and groundwater data collected by the U.S. Geological Survey (USGS) 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 under a five-year comprehensive water resources monitoring program. The...
Occurrence of per- and polyfluoroalkyl substances, Long Island and New York City, New York
State and local county health departments have detected per- and polyfluoroalkyl substances (PFAS) in groundwater downgradient of airports and military and firefighting training areas in Long Island, New York. However, the occurrence and spatial distribution of PFAS throughout the surficial aquifer is not well established. Shallow groundwater samples were collected in 2018 from two observation...
End point rate of shoreline change statistics for New York State coastal wetlands
This data set contains rate of shoreline change statistics for New York State coastal wetlands. Analysis was performed in ArcMap 10.5.1 using historical vector shoreline data from the National Oceanic and Atmospheric Administration (NOAA). Rate of change statistics were calculated using the Digital Shoreline Analysis System (DSAS), created by U.S. Geological Survey, version 5.0. End-point...
Historical shorelines used to calculate rate of shoreline change statistics for New York State coastal wetlands
This dataset includes New York State historical shoreline positions represented as digital vector polylines from 1880 to 2015. Shorelines were compiled from topographic survey sheets from the National Oceanic and Atmospheric Administration (NOAA). Historical shoreline positions can be used to assess the movement of shorelines through time. Rates of shoreline change were calculated in ArcMap 10...
