REMINDER: Final Prioritization for Un-Modified Basins to Be Released

Final Basin Prioritization for basins not affected by Basin Boundary Modifications is expected in early January 2019. Draft Basin Prioritization for modified basins is expected in late February 2019, with final Basin Prioritization in May 2019. The 2018 SGMA Basin Prioritization Timeline has been updated to reflect this.

REMINDER: Alternatives Update

SGMO continues to prioritize review of Alternatives to Groundwater Sustainability Plans. DWR expects to release assessments for each of the submitted Alternatives during the first quarter of 2019. If you have any questions or comments, please email Craig Altare at Craig.Altare@water.ca.gov.

REMINDER: Submit Your GSP Initial Notification

Groundwater sustainability agencies (GSA) are required to notify DWR, in writing, prior to initiating development of a groundwater sustainability plan (GSP). GSAs must submit all applicable GSP initial notification information to DWR using the SGMA Portal – GSP Initial Notification System. The SGMA Portal – GSP Initial Notification System also allows edits to be made to a previously submitted Initial Notification, including the ability to withdraw a submittal.

Also, remember, “If the geographic area to be covered by the plan includes a public water system regulated by the Public Utilities Commission, the groundwater sustainability agency shall provide the written statement to the commission.” See Water Code § 10727.8.

For more information, please see Frequently Asked Questions on GSP Initial Notification Requirements or contact the Regional Coordinators in DWR’s four Regional Offices.

For assistance with the system, please email monica.reis@water.ca.gov.

Connect with Your Basin Point of Contact

DWR has designated Basin Points of Contact to assist local agencies and GSAs as GSPs are developed and implemented and to assist with applications for Technical Support Services and Facilitation Support Services.

To determine your basin point of contact, please see the following links that provide maps and contact information:
