California agriculture has made great strides in improving water use efficiency while increasing output. Since 1970, many water providers have modernized their water delivery systems, and farmers have moved to higher value crops and are utilizing technologies to save water and increase crop yields; this has significantly increased the overall economic value of the state’s agricultural production.
Agricultural and urban water users will continue to improve water conservation strategies moving forward. A survey of growers found that the irrigated acreage using drip irrigation and micro-sprinklers increased 16% between 2001 and 2011, while the acreage of land irrigated using surface irrigation methods decreased by 13%.
In some areas of the state, growers are being encouraged to retain flood irrigation infrastructure to enable on-farm recharge on fields during years with above average precipitation.

Crops like rice, corn, and alfalfa provide over a million and a half acres of potential habitat when managed for multiple-benefits. Waterbird use of flooded habitats depends primarily on the depth and timing of flooding, and the extent and height of vegetation.
