What is the water cycle?

The water cycle is the continuous process of water moving from Earth's oceans, atmosphere and land. This cycle does not move in a particular order but in many different variations because different variables impact it like, topography, temperature and location.      Through precipitation, water condenses, forming a liquid and falling to the Earth as rain, snow, hail or fog. Once on the ground, water either remains in its liquid state, freezes, becoming ice or evaporates, or be...

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 an acre-foot?

@media (max-width: 960px) { .img_right { clear: both !important; float: inherit !important; margin: 0 auto !important; margin-bottom: 20px !important; } }An acre-foot is commonly used to measure water volume. It is the amount of water needed to cover one acre (43,560 square feet) with one foot of water. One acre-foot is equal to 325,851 gallons of water, enough to cover a football stadium with a foot of water. Measuring acre footage is...

What is a drought?

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...

What is the National Flood Insurance Program?

The National Flood Insurance Program is a federal insurance program under which flood-prone areas are identified and flood insurance is made available to residents of participating communities that agree to adopt and enforce floodplain management ordinances to reduce future flood damage.  For additional information and qualification requirements, click here.
