California Code, Water Code - WAT § 22255

When its board deems it in the best interests of the district, the district may regulate the amount of water to be used to irrigate crops within the district when seepage from the irrigation would damage adjacent land inside or outside of the district or may require as a condition precedent to the delivery of water the construction of adequate drainage facilities to prevent damage to the adjacent land.  Whenever the board finds, with respect to land for which there is no existing system for the application of water for the irrigation thereof, that the character of the soil or elevation of the land to be supplied water from the district water supply is such that the application of such water thereto by flooding is likely to require the use of excess quantities of water or to create a hazardous seepage or drainage problem, the board may limit the application of such water to that land to application through overhead sprinkling systems so designed and operated to prevent the use of excess quantities of water, or the creation of a hazardous seepage or drainage problem.
