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.

National Water Information System (NWIS) - Web Mapper application
This mapper provides access to over 1.5 million sites contained in the USGS National Water Information System (NWIS), including sites where surface-water, groundwater, springs, and atmospheric data has been collected.
Surface-water data for New York
Real-time, daily, peak-flow, field measurements, and statistics of current and historical data that describe stream levels, streamflow (discharge), reservoir and lake levels, surface-water quality, and rainfall in New York. Surface-water data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.
Groundwater 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.
Water-quality data for New York
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.
Hydrologic Conditions Mapper (New York)
New York Hydrologic Conditions Mapper: (1) Streamflow conditions (2) Groundwater conditions (3) Precipitation (4) Precipitation departure from normal (5) NYC Water Supply System Status. In addition, historical monthly conditions reports and seasonal condition maps are also available.
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....
StreamStats
StreamStats for New York can be used to estimate (1) instantaneous flood discharges with exceedance probabilities of 0.8, 0.667, 0.5, 0.2, 0.1, 0.04, 0.02, 0.01, 0.005, and 0.002 (1.25-, 1.5-, 2-, 5-, 10-, 25-, 50-, 100-, and 500-year recurrence intervals, respectively) for ungaged, unregulated, rural streams throughout New York; (2) bankfull discharge and channel characteristics of streams in...
