Adjudicated Basin Reporting

The Sustainable Groundwater Management Act (SGMA) established a process for adjudicated basin watermaster or local agencies to report information according to Water Code 10720.8: The watermaster or a local agency within a basin identified in subdivision (a) shall do all of the following:

  • (1) By April 1, 2016, submit to the department [DWR] a copy of a governing final judgment, or other judicial order or decree, and any amendments entered before April 1, 2016.
  • (2) Within 90 days of entry by a court, submit to the department a copy of any amendment made and entered by the court to the governing final judgment or other judicial order or decree on or after April 1, 2016.
  • (3) By April 1, 2016, and annually thereafter, submit to the department a report containing the following information to the extent available for the portion of the basin subject to the adjudication:
    • (A) Groundwater elevation data unless otherwise submitted pursuant to Section 10932.
    • (B) Annual aggregated data identifying groundwater extraction for the preceding water year.
    • (C) Surface water supply used for or available for use for groundwater recharge or in-lieu use.
    • (D) Total water use.
    • (E) Change in groundwater storage.
    • (F) The annual report submitted to the court.
Approach for Developing Adjudicated Basin Reporting System

DWR reviewed available adjudication judgements and watermaster annual reports to provide a scope for this system.  DWR compiled a list of watermasters and water managers of adjudicated areas specified in the SGMA. DWR developed a draft template for the online reporting tool and presented the template to water managers at an in-person and WebEx workshop on February 3, 2016.  DWR has revised the draft template following the valuable interactions at the February 3 workshop.

How to Submit SGMA information for Adjudicated Areas

DWR, in conjunction with their contractor, is developing a detailed data model and building a web-based application system and will roll out this new system for use in early March. The Adjudicated Basin Reporting Website is:
