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.

Echosounder Points, Cannonsville Reservoir, 2015
From 2013 to 2015, bathymetric surveys of New York City’s six West of Hudson reservoirs (Ashokan, Cannonsville, Neversink, Pepacton, Rondout, and Schoharie) were performed to provide updated capacity tables and bathymetric maps. Depths were surveyed with a single-beam echo sounder and real-time kinematic global positioning system (RTK-GPS) along planned transects at p
Bathymetric and tidal discharge data for Wilderness Breach, Fire Island National Seashore, Long Island, NY, May 14, 2015 - Bathymetry Contours: U.S. Geological Survey data release
In 2012, Hurricane Sandy created an open breach in the barrier island system along the south shore of Long Island, N.Y. This breach formed at a location known as Old Inlet and migrated rapidly westward over the winter storm season following Hurricane Sandy. On May 14, 2015, U.S. Geological Survey (USGS) New York Water Science Center (NYWSC) personnel collected data to evaluate ch

Bacteria, nutrients, and contaminants of emerging concern in shallow groundwater of nearshore environments, Suffolk County, New York, 2013
Onsite wastewater disposal systems (OWDS) in coastal regions of Long Island, New York, contribute bacteria, nutrients, and organic wastewater-associated compounds (including pharmaceuticals, personal care and domestic use products referred to here as contaminants of emerging concern (CECs)) to downgradient shallow groundwater in nearshore settings. Many of the densely popula
