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.

Water use data for New York

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 Beach Status

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....

Long Island Depth to Water Viewer 2013

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.
