BILL NUMBER: AB 647AMENDED BILL TEXT AMENDED IN ASSEMBLY MAY 5, 2015 AMENDED IN ASSEMBLY APRIL 15, 2015 INTRODUCED BY Assembly Member Eggman (Principal coauthor: Assembly Member Olsen) (Coauthor: Senator Berryhill) FEBRUARY 24, 2015 An act to amend Section 1242 of the Water Code, relating to water. LEGISLATIVE COUNSEL'S DIGEST AB 647, as amended, Eggman. Beneficial use: storing of water underground. Under existing law, the right to water or to the use of water is limited to that amount of water that may be reasonably required for the beneficial use to be served. Existing law provides for the reversion of water rights to which a person is entitled when the person fails to beneficially use the water for a period of 5 years. Existing law declares that the storing of water underground, and related diversions for that purpose, constitute a beneficial use of water if the stored water is thereafter applied to the beneficial purposes for which the appropriation for storage was made. This bill would declare that the storing of water underground constitutes a beneficial use of water if the diverted water is used while it is in underground storage for specified purposes. This bill would state the intent of the Legislature that this storage of water underground not injure any legal user of the water involved. This bill would provide that the period for the reversion of a water right does not include any period when the water is being used in the aquifer or storage area or is being held in storage for later application to beneficial use, as prescribed. Vote: majority. Appropriation: no. Fiscal committee: yes. State-mandated local program: no. THE PEOPLE OF THE STATE OF CALIFORNIA DO ENACT AS FOLLOWS: SECTION 1. Section 1242 of the Water Code is amended to read: 1242.
