§ 833. Except as provided in subdivision (b), this chapter applies to actions that would

(a) Except as provided in subdivision (b), this chapter applies to actions that would comprehensively determine rights to extract groundwater in a basin, whether based on appropriation, overlying right, or other basis of right. (b) This chapter does not apply to any of the following: (1) An action that concerns only allegations that a groundwater extraction facility, or group of facilities, is interfering with another groundwater extraction facility or facilities and does not involve a comprehensive allocation of the basin’s groundwater supply. (2) An action that concerns only claims to extract, or to prevent interference with extractions of, a specific source of groundwater recharge and does not involve a comprehensive allocation of the basin’s groundwater supply. (3) An action that can be resolved among a limited number of parties and does not involve a comprehensive determination of rights to extract groundwater within the basin. (4) An adjudicated area described in subdivisions (a) to (d), inclusive, of Section 10720.8 of the Water Code, unless a court with jurisdiction over a proposed expansion of the adjudicated area orders that the proceeding be conducted in accordance with this chapter. (c) If the court finds that including an interconnected surface water body or subterranean stream flowing through known and definite channels is necessary for the fair and effective determination of the groundwater rights in a basin, the court may require the joinder of persons who claim rights to divert and use water from that surface water body or subterranean stream in a comprehensive adjudication conducted pursuant to this chapter. (d) If the court finds that claims of right to extract or divert only minor quantities of water, not to exceed five acre-feet of water per year, would not have a material effect on the groundwater rights of other parties, the court may do either of the following: (1) Exempt those claimants with respect to those claims for only minor quantities of water, but a person who is exempted may elect to continue as a party to the comprehensive adjudication. (2) Treat those claimants separately from other parties to the comprehensive adjudication by separately processing and entering orders with respect to those persons, in order to reduce their burden of participation and more efficiently administer the case.
