Data and Tools
Get current water conditions that are important to you, such as water levels, streamflow, temperatures, and more.
WaterQualityWatch (http://waterwatch.usgs.gov/wqwatch/) is a USGS web site that provides access to real time water-quality data collected in surface waters throughout the United States as part of the USGS mission to describe water resources. Measurements include streamflow (through WaterWatch) water temperature, specific conductance, pH, dissolved oxygen, turbidity, and nitrate.
Actively-measured periodic, continuous, and/or real-time wells with at least 20 years of measurements.
Water levels and well information for wells that have been measured by the USGS or USGS cooperators at least once within the past 13 months.
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 Jersey. Surface water data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.
WaterWatch is a U.S. Geological Survey (USGS) World Wide Web site that displays maps, graphs, and tables describing real-time, recent, and past streamflow conditions for the United States.
Select your favorite USGS streamgage from the USGS WaterAlert map, then set water stage or streamflow thresholds to receive instant notifications sent to your email address or mobile device. Click the image at left or the title above to go to the map and select your site(s).
Want to know what's happening right now? Request real-time information from any USGS streamgage with the USGS WaterNow text service. This service responds to your text message with information about the current stage, streamflow, or other parameters collected at the gage.
Annual Water Data Reports were published annually for many decades as static archival products that supplemented direct access to current and historical water data provided by the National Water Information System (NWIS). This site helps users access historical Water Data Reports, electronic Site Data Sheets, or current on-demand, print-ready Water-Year Summaries.
The USGS StreamStats website is a GIS-based web tool for estimating streamflows at gaged and ungaged locations. Features similar to the NSS program are presented to users with no programs to install. Users can visit the StreamStats website linked here and click on a stream location on the interactive map to compute estimated streamflows for floods and other statistics.
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.
Data from rain gages that provide real-time data are relayed to the USGS and are transmitted from each station at hourly intervals. Real-time data available on these web pages are provisional data that have not been reviewed or edited.
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.
