| Abstract: | Urban land use and water use in the Antelope Valley, California, have increased greatly since the devel- opment of the valley began in the late 1800‘s. Ground water always has been a major source of supply in this area because of limited local surface-water resources. Ground-water pumpage reportedly increased from about 29,000 acre-feet in 1919 to about 400,000 acre-feet in the 1950‘s. Declines in ground-water levels and increased costs of electrical power in the 1970‘s resulted in a reduction in the quantity of ground-water pumped annually for irrigation uses. Ground-water pumpage was further reduced in the 1970‘s following the completion of the California Aqueduct, which conveys water from northern California. Total annual reported ground-water pumpage decreased to a low of about 53,200 acre-feet in 1983 and increased again to about 91,700 acre-feet in 1991. Rapid urban development and the 1987-92 drought renewed concern about a possible return to extensive ground-water- storage depletion and increased land subsidence. Water-demand forecasts in 1980 for the Antelope Valley indicated that total annual demand by the year 2020 was expected to be about 250,000 acre- feet per year, with agricultural uses to be about 65 percent of this total demand. In 1990, total demand. In 1993, preliminary forecasts for total demand for 2010 ranged from about 127,000 to 329,000 acre-feet with urban water uses accounting for all but a few percent of the total anticipated demand. This history of forecasts indicates that expectations change with time. Factors that affect water demand change and different forecasting methods are used. Water-conservation options may be adopted to employ best-management practices that would further influence future water demands in the Antelope Valley. |
