Beneficial use or beneficial purpose: The causing, suffering or permitting of any water pumped or flowing from any well to be used for the purpose of irrigation of lands and/or for domestic use and/or for the propagation of fish.
Irrigation of land: The artificial application of water to lands whenever rainfall is insufficient to meet the full water requirements of crops, applied to lands in such quantities and in such manner, from time-to-time during the growing season of the trees or plants being irrigated, as will provide sufficient moisture to promote plant growth, having reference to the particular kind of crops grown and the particular type of soil involved.
Propagation of fish: The breeding and/or propagating of edible or pet species of fish where such breeding and/or propagation is carried on as a commercial enterprise.
Unnecessarily flow: The causing, suffering or permitting water flowing from an artesian well or pumped from a pumping well to be stored or used for any purpose other than a beneficial use or beneficial purpose, as defined in this section.
Waste of water:
A. The causing, suffering or permitting of any water pumped or flowing from any well to run into any river, creek or other natural watercourse, or channel, or into any bay or pond, or artificial reservoir, or into any street, road or highway, unless it be used thereafter for a beneficial purpose; and where such water is caused, suffered or permitted to be run into any pond or artificial reservoir, such storing of water shall be deemed a waste of water, unless it is used thereon for the beneficial purposes of domestic use, and or propagation of fish, and/or thereafter removed therefrom and used for the beneficial purpose of irrigation.
B. The causing, suffering or permitting any water pumped or flowing from any well to run upon the land of any person, or upon the public lands of the United States, or the State, unless it be used thereon for the beneficial purposes of irrigation thereof, or for the propagation of fish.
C. The causing, suffering or permitting any water pumped or flowing from any well to be used for a beneficial purpose, where such beneficial use allows more than five percent of the water so pumped to escape in such a way as would define the use of such escaped water to be classified as "waste of water" under this section.
Water well orwells: An artificial hole made in the ground through which water naturally flows from subterranean sources to the surface of the ground, commonly known and designated as an artesian well; or any well from which water is obtained by means of a pump or other mechanical device, commonly known and designated as a pumping well.
