Nevada WaterQualityWatch

WaterQualityWatch ( 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.

Surface-water Data for New Jersey

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.

Annual Water Data Reports

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.

Precipitation for New York

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 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.
