UC Delivers

The Colorado River is the only source of irrigation and drinking water in the Imperial Valley and the main source in Mexicali, Mexico. As much as 4.5 million acre-feet of Colorado River water is used every year to irrigate more than 500,000 acres in the Imperial Valley and in the Mexicali Valley, Mexico. Growers in Southern California are under continuous pressure to conserve water and transfer some of the agricultural water to urban regions of the state. The current water transfer agreement between the Imperial Irrigation District and the San Diego County Water Authority calls for transfer of up to 200,000 acre-feet annually of Imperial Valley-Colorado River water. Increased irrigation efficiency using CIMIS-based irrigation scheduling techniques and other water conservation practices is needed to supply the water demand in Southern California and northern Baja California.
