How is the flow of the river measured?

How is the flow of the river measured?

A rivers rate of flow is measured in terms of cubic feet per second (cfs) or how many cubic feet of water (volume) passes by a gaging location for a period of one second (one cubic foot of water is approximately 7.5-gallons). Gages are managed by the United States Geological Survey (USGS) at intervals along a watercourse to measure the rate of flow. You can find information on streamflow on the Brazos River and its tributaries flow by going to this link.

What is the Brazos River?

What is the Brazos River?

The Brazos River is the longest river contained entirely in Texas, with its watershed stretching from New Mexico to the Gulf of Mexico. The Brazos River draw lies approximately 50 miles west of the Texas-New Mexico border, beginning a watershed that stretches 1,050 miles and comprises 44,620 square miles, 42,000 of which are in Texas.The Brazos River proper is formed at the confluence of the upper forks of the river, the Salt and Double Mountain, in Stonewall County. The Clear Fork joins the riv...

What is cubic foot per second?

The measurement cubic foot per second (cfs or ft3/s) is the rate of water movement representing a volume of 1 cubic foot passing a given point during 1 second.  This measurement is equivalent to approximately 7.48 gallons per second or 448.8 gallons per minute.

What is the Clear Fork of the Brazos River?

The Clear Fork is one of the longest tributaries of the Brazos River. It originates as a draw in Scurry County and runs for about 180 miles through Fisher, Jones, Shackelford and Throckmorton counties before joining the river’s main stem in Young County north of Possum Kingdom Lake.For a full-sized map, click here.

What is the USGS?

The United States Geological Survey (USGS) is a federal scientific agency that works in biology, geography, geology and hydrology. USGS is the nation’s primary civilian mapping agency. The agency also monitors streams and other bodies of water across the country for flow and depth. Among its other activities, USGS also monitors earthquakes and volcanic activity.The USGS web site may be found by clicking here.

What is a river basin?

A river basin is the area drained by a river and its tributaries. A river basin is synonymous with the term “watershed.”  For example, the Brazos River basin refers to the same area as the Brazos River watershed.  photo courtesy Texas Parks and Wildlife
