This is a list of rivers in the continental United States by average discharge (streamflow) in cubic feet per second. All rivers with average discharge more than 15,000 cubic feet per second are listed.
In fiscal year 2008, the USGS provided 35% of the funding for everyday operation and maintenance of gauges. [8] Additionally, USGS uses hydrographs to study streamflow in rivers. A hydrograph is a chart showing, most often, river stage (height of the water above an arbitrary altitude) and streamflow (amount of water, usually in cubic feet per ...
The raster hydrographs in WaterWatch, like those developed by Koehler, depict years on the y-axis and days along the x-axis. Users can choose to plot streamflow (actual values or log values), streamflow percentile, or streamflow class (from 1, for low flow, to 7 for high flow), for Daily, 7-Day, 14-Day, and 28-Day streamflow.
A USGS gauging station on the Scioto River below O'Shaughnessy Dam near Dublin, Ohio. The USGS operates the streamgaging network for the United States, with over 7400 streamgages. Real-time streamflow data [17] are available online.
Within the USGS, the Water Resources Division carries the responsibility for monitoring water resources. To establish a stream gauge, USGS personnel first choose a site on a stream where the geometry is relatively stable and there is a suitable location to make discrete direct measurements of streamflow using specialized equipment.
Rivers with an average discharge of 5,000 m 3 /s or greater, as a fraction of the estimated global total.. This article lists rivers by their average discharge measured in descending order of their water flow rate.
The United States Geological Survey (USGS) defines it as the period between October 1 of one year and September 30th of the next, [2] [3] as late September to early October is the time for many drainage areas in the US to have the lowest stream flow and consistent ground water levels. The water year is designated by the calendar year in which ...
