Sustainable Groundwater Management Act: groundwater adjudication.

The California Constitution requires that the water resources of the state be put to beneficial use to the fullest extent of which they are capable. Existing law specifies the jurisdiction of the courts. Under existing law, courts may adjudicate rights to produce groundwater and exercise other powers relating to the supervision of a groundwater basin. Existing law authorizes a court to order a reference to the State Water Resources Control Board, as referee, of any and all issues involved in a suit brought in any court of competent jurisdiction in this state for determination of rights to water. This bill would authorize the state to intervene in a comprehensive adjudication conducted as specified in AB 1390 of the 2015–16 Regular Session. Existing law, the Sustainable Groundwater Management Act, requires all groundwater basins designated as high- or medium-priority basins by the Department of Water Resources that are designated as basins subject to critical conditions of overdraft to be managed under a groundwater sustainability plan or coordinated groundwater sustainability plans by January 31, 2020, and requires all other groundwater basins designated as high- or medium-priority basins to be managed under a groundwater sustainability plan or coordinated groundwater sustainability plans by January 31, 2022, except as specified. The act authorizes a local agency to request that the department revise the boundaries of a basin. This bill, in an adjudication action to determine rights to groundwater in a basin that is required to have a groundwater sustainability plan under the act, would require the court to manage the proceedings in a manner that minimizes interference with the timely completion and implementation of a groundwater sustainability plan, avoids redundancy and unnecessary costs in the development of technical information and a physical solution, and is consistent with the attainment of sustainable groundwater management within the timeframes established by the act. The bill would authorize an entity that is directed by the court in an adjudication action to file the request that the department revise the boundaries of a basin. The act authorizes the state board to designate certain high- and medium-priority basins as a probationary basin if prescribed criteria are met. The act authorizes the state board to develop an interim plan for a probationary basin if the state board, in consultation with the department, determines that a local agency has not remedied a deficiency that resulted in designating the basin as a probationary basin within a certain timeframe. The act also requires the department, at least every 5 years after initial submission, to review any available groundwater sustainability plan or alternative and the implementation of the corresponding groundwater sustainability program for consistency with the act, including achieving the sustainability goal. The act requires the department to issue an assessment for each basin for which a plan or alternative has been submitted that may include recommended corrective actions to address any deficiencies identified by the department. The bill would prohibit the provisions relating to probationary basins and interim plans from applying to a judgment approved by the court if the judgment is submitted to the department for evaluation and assessment and the department determines that the judgment satisfies the objectives of the act for the basin. The bill would require the department to submit to the court assessments and any recommended corrective actions for these judgments and would require the court, after notice and, if necessary, an evidentiary hearing, to determine whether to amend the judgment to adopt the department's recommended corrective actions. This bill would prohibit a court from approving entry of judgment in an adjudication action for a basin required to have a groundwater sustainability plan under the act unless the court finds that the judgment will not substantially impair the ability of a groundwater sustainability agency, the board, or the department to comply with the act and to achieve sustainable groundwater management.
