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.
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.
USGS researchers publish the results of their science in a variety of ways, including peer-reviewed scientific journals as well as in one of a variety of USGS Report Series [35] that include preliminary results, maps, data, and final results. A complete catalog of all USGS publications is available from the USGS Publications Warehouse. [36]
The first routine measurements of river flow in England began on the Thames and Lea in the 1880s, [2] and in Scotland on the River Garry in 1913. [3] The national gauging station network was established in its current form by the early 1970s and consists of approximately 1500 flow measurement stations supplemented by a variable number of temporary monitoring sites.

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 ...
The Animas River is the largest tributary in terms of stream flow, but drains a comparatively slim watershed of 1,370 square miles (3,500 km 2). [3] [8] In the 21st century, the snowpack in the San Juan Mountains has often been diminished by warming winter temperatures which has led to concerns about the long-term water supply for the San Juan ...
