The rate of the river flow is measured in cubic feet per second (cfs), which is the measure of the volume of water passing any given point in a river in one second. One cubic foot of water is about the size of a beachball. These levels are measured by the United States Geological Survey (USGS) along the course of the waterflow at different points, or subsections, along a marked line. A river will typically be measured approximately 25 to 30 times at regularly spaced locations. USGS gage loc...

A drought is generally considered to be a prolonged period of less-than-normal precipitation such that the lack of water causes below-average streamflow or lake levels, lowered soil moisture, crop damage, or economic losses.  Droughts are globally the second-most costly weather event behind hurricanes, according to National Geographic. In Texas, during the 2011 drought, an estimated $7.62 billion was lost by farmers and ranchers, according to Texas AgriLife. Not only are droughts one o...

The Brazos River is the longest river contained entirely in Texas, with its watershed stretching from New Mexico to the Gulf of America. 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 t...

A floodplain is any ordinarily dry land area susceptible to inundation by water. This area is usually low, flat, and next to a stream or other body of water. Living on a floodplain can be especially dangerous in the circumstance that flooding does occur. There is always some risk for those on a floodplain, whether it’s people, businesses, or agriculture. Some floodplains are clearly defined by natural features, by infrastructure made by people, or not clearly outlined.Some floodplains are ...

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.

The headwater is the upper reaches of a stream or reservoir. It can also include the merging of streams that come together to form a river.The Brazos River’s headwater begins at the confluence of its Salt Fork and Double Mountain Fork near the eastern boundary of Stonewall County. The river stretches a total of 938 miles across the state of Texas.Knowledge surrounding a stream or river’s headwater can provide important information about the sources or causes of pollution and nutrient...
