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.

Brook trout toxicity data from bioassays conducted in Western Adirondack Streams, 2001-03 and 2015-17

This dataset is composed of a single data table containing survival data and ancillary measurements for brook trout bioassays conducted in streams of the Western Adirondack Mountains during 2001-03 and 2015-17. At each stream site, 4 replicate bottles, each containing five young-of-year brook trout, are exposed to ambient stream waters for approximately one month during spring.

Horizontal-to-Vertical Spectral Ratio Soundings and Depth-to-Bedrock Data for Geohydrology and Water Quality Investigation of the Unconsolidated Aquifers in the Enfield Creek Valley, Town of Enfield, Tompkins County, New York, April 2013 - August 2015

From April 2013 to August 2015, the U.S. Geological Survey, in cooperation with the Town of Enfield and the Tompkins County Planning Department, collected horizontal-to-vertical seismic soundings at 69 locations in the Enfield Creek valley to help determine thickness of the unconsolidated deposits and depth to bedrock. The HVSR technique, commonly referred to as the passive-seismic metho

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.

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 observ
