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.
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.
The U.S. Geological Survey's (USGS) National Water Information System (NWIS) is a comprehensive and distributed application that supports the acquisition, processing, and long-term storage of water data.
Real-time and historical water data for New York
Data from wells, springs, test holes, tunnels, drains, and excavations in New York; well location data includes information such as latitude and longitude, well depth, and aquifer. Groundwater level data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.
Chemical, physical, and biological properties of water, sediment, and tissue samples from New York. Water-quality data are collected as either discrete field measurements or as continuous time-series data from automated recorders.
Water-use data are collected by area type (state, county, watershed, or aquifer) and source (rivers or groundwater), and category (such as public supply or irrigation). Water-use data has been reported every five years since 1950. The USGS works with local, State, and Federal agencies as well as other organizations to collect and report withdrawals.
Nowcast predicts water quality conditions at select beach swimming areas in the Great Lakes. Nowcast estimates conditions by merging environment and climate data with variables measured at a beach by 8 AM each morning and entering them into a computer program which provides a probability from 1 to 100 as to whether or not the beach has exceeded the bathing-water standard of 235 units of E. coli.

USGS collects groundwater data at varying measurement frequencies to monitor the hydrologic conditions on Long Island, New York. Each year during April and May, the USGS conducts a synoptic survey of water levels to define the spatial distribution of the water table and potentiometric surfaces within the three main water-bearing units underlying Long Island.
The USGS Flood Event Viewer helps USGS and its partners to track of the storm and its impact on surface water levels. A storm track field is included from NOAA's National Hurricane Center, and real-time USGS streamgage data and Rapid Deployment Gage data are linked through this map-based product.
