Nothing grows without water.
Of the rain or snow that falls in California each year, about two-thirds goes straight to the environment where it evaporates or is taken up by trees and other native plants. The remaining water runs off into rivers and steams. Of that runoff, more than 30 percent runs directly to the Pacific Ocean or other saltwater bodies without being trapped. Agriculture accounts for 43 percent and urban uses for 11 percent. California farmers make every drop of water count.
