Volume of water in a stream passing a given point at a given moment in time, expressed as a measure of volume per unit of time, i.e. cubic feet per second, million gallons per day, or gallons per minute.
Description and illustrations of hydroacoustic current meters for measuring the discharge in streams and rivers with links to wading discharge measurements, project progress and plans and references.
Portal for Missouri River Infolinks, a clearinghouse to multiple links giving Missouri information, photo gallery, river weather forecast, projects and features, maps, meetings, history, and science research.
National Streamflow Information Program home page describing the operation and maintenance of 7000 streamgages, overview of the program, system for collection of streamflow data, maintaining of historic streamflow data, and available reports.
Description and history of the stream-gaging program of the USGS with information on the networks and monitoring stations, data-collection process, uses of streamflow data, and evaluation of the program.
Site to locate most recent or archive reports for end-of-the-month hydrologic conditions with descriptions, data, charts, and maps giving an overview of water conditions during the month for the state of New York.
Report of completed studies that have investigated the response of river and stream channels in Kansas to a variety of human-caused and natural disturbances.
Links to model documentation, search engine, and help for (FEQ) Full Equations (a computer model for one-dimensional unsteady flow in open channels and through control structures), and the Full Equations Utilities package (FEQUTL).
The USGS collects continuous stage, discharge, and other instantaneous time-series data on the nations rivers. This Archive provides streamflow data and historical data, often several years worth.
Historical maps and animations of maps for monthly and annual streamflow conditions by water year showing generalized contour patterns of streamflow conditions. Maps are for the United States, Canada, and Puerto Rico.
Maps and explanations of continuous real-time data collection methods and results, including water temperature, turbididty, specific conductance, dissolved oxygen, pH, and stream discharge values.
