GSA Formation Notifications

The local agencies included on the GSA Formation Table (below) have decided to become or form groundwater sustainability agencies (GSAs). The portion of a basin a local agency intends to manage is included as part of its posted GSA formation notice and is shown on the GSA Interactive Map. A local agency that has formed a GSA will only be identified by DWR as an exclusive GSA if the provisions of Water Code §10723.8 are met. Only exclusive GSAs can coordinate to develop and implement a GSP for a basin and submit that GSP to DWR for review. If two or more local agencies separately decide to become GSAs in all or a portion of the same area of a basin (within 90 days of the initial posted notice), then none of the GSAs will become exclusive GSAs until the overlap is resolved. For reference, the original SGMA language and the language amended by SB 13 that discuss overlap and service area is excerpted below:

Original SGMA §10723.8(b): Except as provided in subdivision (d), 90 days following the posting of the notice pursuant to this section, the GSA shall be presumed the exclusive GSA within the area of the basin the agency is managing as described in the notice, provided that no other notice was submitted.

Amended SGMA §10723.8(c): The decision to become a GSA shall take effect 90 days after the department posts notice under subdivision (b) if no other local agency submits a notification under subdivision (a) of its intent to undertake groundwater management in all or a portion of the same area. If another notification is filed within the 90-day period, the decision shall not take effect unless the other notification is withdrawn or modified to eliminate any overlap in the areas proposed to be managed. The local agencies shall seek to reach agreement to allow prompt designation of a GSA. If agreement is reached involving a material change from the information in the posted notice, a new notification shall be submitted under subdivision (a) and the department shall post notice under subdivision (b).

Amended SGMA §10723.8(d): Except as provided in subdivisions (e) and (f), after the decision to be a GSA takes effect, the GSA shall be presumed to be the exclusive GSA within the area of the basin within the service area of the local agency that the local agency is managing as described in the notice.

The GSA Formation Table includes:

  • The name of the local agency that submitted the GSA formation notice. A local agency may have submitted a single GSA formation notice for multiple basins, or multiple notices for multiple areas.
  • The name and number of the groundwater basin or subbasin as defined in DWR’s Bulletin 118-2003. If basin names and numbers are modified, this information may change. (Water Code §10722 et seq.)
  • The county that is part of the basin described in the notice. A basin may be located in multiple counties.
  • The date the GSA notice was posted, which initiates the 90-day period described in Water Code §10723.8(c). DWR posts all complete notices within 15 days of receipt.
  • The final column indicates the GSA status of the local agency or identifies the date the 90-day period for that portion of the basin described in the notice ends. If two or more local agencies file GSA formation notices for all or part of the same area of a basin, the 90-day date will be replaced with “Overlap.” If no other local agency files a GSA formation notice for that portion of the basin within 90 days, or if the GSA overlap has been resolved, the 90-day date will be replaced with “Exclusive” and no other GSA formation notice will be posted for that area unless the exclusive GSA withdraws its notice. The local agencies involved in GSA formation overlap shall seek to reach agreement to resolve the overlap by June 30, 2017, or risk potential intervention by the State Water Resources Control Board.

Local agencies or GSAs that have either withdrawn their notices or opted out of their role as an exclusive GSA are located here.
