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.

Stream and Lake Average Water-Level Altitudes, April-May 2016
Continuous records of water level altitude at 15 U.S. Geological Survey (USGS) streamgaging stations (13 streams, 1 lake and 1 pond) were retrieved from the National Water Information System (NWIS) and averaged for the months of April and May, 2016. This shapefile consists of the locations of those sites and includes water level altitude data stored in the attribute table. The shapefile was...
Approximate Regional Groundwater Divide on Long Island, New York, April-May 2016
This groundwater divide feature was approximated from and interpolated water table raster for Long Island, April-May 2016. Generally, the highest altitudes of the water table were used to draw the groundwater divide, which implies the groundwater flow direction. The feature is presented in Sheet 1 of Scientific Investigations Map 3398.
Water Table Data in the Upper Glacial and Magothy Aquifers, April-May 2016
Water level altitudes were measured at 275 observation wells and 1 supply well screened in the upper glacial and Magothy aquifers during April and May of 2016. This shapefile consists of the locations of those sites and includes water level altitude data stored in the attribute table. The shapefile was created and intended for use with geographic information system (GIS) software. The...
Water Level Data in the Magothy and Jameco Aquifers, April-May 2016
The potentiometric surface altitude was measured at 61 observation wells and 27 supply wells screened in the Magothy aquifer and the contiguous and hydraulically connected Jameco aquifer during April and May of 2016. This point shapefile consists of the locations of those sites where water levels were measured and includes potentiometric surface altitude values which are stored in the...
Potentiometric Surface Contours of the Lloyd and North Shore Aquifers, April-May 2016
This polyline shapefile consists of digital contours that represent the potentiometric-surface altitude of water in the Lloyd and contiguous North Shore aquifer beneath Nassau and Suffolk Counties, Long Island, New York. The U.S. Geological Survey constructed a potentiometric-surface altitude map using ground-water levels measured in the Lloyd and North Shore aquifers during the spring of 2016...
Water Table Contours in the Upper Glacial and Magothy Aquifers, April-May 2016
This polyline shapefile consists of digital contours that represent the water table altitude in the upper glacial and Magothy aquifer beneath Long Island, New York. The U.S. Geological Survey constructed a water table altitude map using ground-water levels measured in the upper glacial and Magothy aquifers during the spring of 2016. Contours were constructed at a scale of 1:125,000 from water-...
Depth to Water Data in the Upper Glacial and Magothy Aquifers, April-May 2016
The depth to water table was measured at 276 groundwater monitoring wells (observation and supply) screened in the upper glacial and Magothy aquifers during April and May of 2016. This shapefile consists of the locations of those sites where water levels were measured and includes depth-to-water values which are stored in the attribute table. The shapefile was created and intended for use with...
Potentiometric Surface Contours of the Magothy and Jameco Aquifers, April-May 2016
This polyline shapefile consists of digital contours that represent the potentiometric-surface altitude of water in the Magothy and contiguous Jameco aquifer beneath Long Island, New York. The U.S. Geological Survey constructed a potentiometric-surface altitude map using ground-water levels measured in the Magothy and Jameco aquifers during the spring of 2016. Contours were constructed at a...
Water Level Data in the Lloyd and North Shore Aquifers, April-May 2016
This point shapefile consists of digital points that represent water level altitudes in the Lloyd and North Shore aquifers of Long Island, New York. The U.S. Geological Survey measured 55 observation wells and 5 supply wells screened in the Lloyd aquifer and the contiguous and hydraulically connected North Shore aquifer. This point shapefile is a digital representation of the water levels...
Depth to the Water Raster on Long Island, New York, 2016
The depth to water table was measured at 276 groundwater monitoring wells (observation and supply) screened in the upper glacial and Magothy aquifers during April and May of 2016. This raster data set was interpolated from the water level data collected at those sites and represents a continuous surface of the estimated depth to water for hydrologic conditions for Nassau and Suffolk Counties,...
