A satellite image of circular fields characteristic of center pivot irrigation, Kansas Farmland with circular pivot irrigation. Center-pivot irrigation (sometimes called central pivot irrigation), also called water-wheel and circle irrigation, is a method of crop irrigation in which equipment rotates around a pivot and crops are watered with sprinklers.
The canal network of 1,100 miles (1,800 km) is managed by the Lower Colorado River Authority (LCRA) and provides water to farm a region with inadequate and unreliable rainfall. Texas produces 7% of the nation's rice, and the majority of this rice is grown along the Colorado River. Nine pumping stations provide water to the canals.
The government used irrigation and dam-building to further social goals like poverty relief by creating construction jobs for poor whites and irrigation schemes to increase white farming. One of their first significant irrigation projects was the Hartbeespoort Dam , begun in 1916 to elevate the living conditions of the 'poor whites' in the ...
The treatment of waste water issuing from raceway farms is a major concern. Fish fecal matter and uneaten feed are typically the major elements of solid waste produced in raceway aquaculture farms. These can adversely impact the environment in the receiving water body.

Fish farming or pisciculture involves commercial breeding of fish, most often for food, in fish tanks or artificial enclosures such as fish ponds. It is a particular type of aquaculture , which is the controlled cultivation and harvesting of aquatic animals such as fish, crustaceans , molluscs and so on, in natural or pseudo-natural environments.
Rio Grande dams and diversions are structures that store water along the Rio Grande or its tributaries, or that divert water for use in irrigation. The first diversions were made by the Pueblo Indians over 1,000 years ago. More permanent diversions were built by the Spanish in New Mexico to feed acequias, or shared irrigation canals. [1]
The aquaculture or farming of piscivorous fish, like salmon, does not help the problem because they need to eat products from other fish, such as fish meal and fish oil. Studies have shown that salmon farming has major negative impacts on wild salmon, as well as the forage fish that need to be caught to feed them.
