Welcome to DWR's SGMA Portal

This portal allows local agencies, groundwater sustainability agencies (GSAs), and watermasters to submit, modify, and view the information required by the Sustainable Groundwater Management Act (SGMA), and enables the public and interested stakeholders to view submitted information and provide comments, where applicable. No login is required for public access.

  • For local agency, GSA, and watermaster access an account is required.
  • If you have an account, sign in here.
  • If you do not have an account, you can register here.
  • If you forgot your passsword, you can recover it here.
  • Once an account is created in the SGMA Portal, a local agency, GSA, or watermaster will only have access to the information that it has uploaded, as well as the information available on the public access site.

The SGMA Portal will coordinate DWR's SGMA responsibilities related to the following topics:

  • GSA: Local agencies can submit their GSA Formation Notification and can make changes to that notification in accordance with Water Code §10723 et seq. Information will not be posted to the public access site until reviewed for completeness. Additional Information is available on DWR's GSA Website
  • GSP: GSAs can coordinate to develop one or more groundwater sustainability plans (GSPs) in a basin and can submit information in accordance with Water Code §10727 et seq. and the GSP Emergency Regulations. Additional Information is available on DWR's GSP Website
  • Alternatives: Local agencies or GSAs can submit Alternatives as described in Water Code §10733.6. Additional Information is available on DWR's Alternative Submittal Website
  • Adjudicated Areas: The adjudicated areas listed in Water Code §10720.8 can access information uploaded on April 1, 2016, and submit annual reports. Additional Information is available on DWR's Adjudicated Area Website

If you have questions or comments, please contact the DWR representative identified on the specific SGMA topic. If you have general SGMA questions, please email DWR at sgmps@water.ca.gov.

GSA Formation Notification System

Local Agency/Entity Access

Groundwater Sustainability Agency (GSA)

This system is intended for use by local agencies forming GSAs in accordance with Water Code §10723 et seq. and for the public to readily view that information. Local agencies must sign in to the system and upload all required information before that notice will be posted. DWR will only post complete notices to the public viewing site. The following should be considered when deciding to become or form a GSA:

  • Only local agencies are eligible to become or form GSAs.
  • A combination of local agencies may form a GSA by using any of the following methods: (1) a joint powers agreement (JPA); or (2) a memorandum of agreement (MOA) or other legal agreement. Each local agency coordinating through a MOA or other legal agreement should provide a resolution to show GSA management intent.
  • The agencies listed in Water Code §10723 are exclusive within their respective statutory boundaries.
  • The decision to become a GSA shall take effect as provided in Water Code §10723.8.
  • Local agencies should clearly state groundwater management intent in the GSA formation information; for example, information that clearly states a local agency intends to form a GSA within a particular area(s), within a particular county(s), and within a particular basin(s).
  • Due to positional accuracy associated with GIS shapefiles, a GSA shapefile may unintentionally and slightly extend into an adjacent basin or county. A 500-foot buffer zone has been applied to the GSA Map to account for GIS shapefile variability. Local agencies should coordinate with each other to improve the accuracy of their GIS shapefiles.
  • Local agencies and GSAs should be contacted to determine parcel-level detail related to GSA, county, and basin boundaries.
  • A local agency, or a combination of local agencies, does not effectively become a GSA until the provisions of Water Code §10723.8 are met. These provisions address overlapping GSA formation notices within a 90-day period.
  • DWR will consider clear management intent when determining the extent of overlap, if any. Any GSA overlap over 500 feet will be considered intentional overlap. Adjacent local agencies or GSAs should coordinate to resolve unintended GIS boundary overlap.

For additional information regarding GSAs and DWR's role in their formation, please contact Mark Nordberg at Mark.Nordberg@water.ca.gov or 916-651-9673. The State Water Resources Control Board can be reached at groundwater_management@waterboards.ca.gov.

Alternative Reporting System

  • Click here to comment on Submitted Alternatives (this link should take you to the list of submitted alternatives).
  • Instructions for Public Comments.

Local Agency/Entity Access


The Sustainable Groundwater Management Act (SGMA) established a process for local agencies to submit an Alternative (to a Groundwater Sustainability Plan) to DWR by January 1, 2017, and every five years thereafter (see Water Code §10733.6). This tool is for use by submitting agencies to submit Alternatives and for the public to access and comment on Alternatives. Additional Information is available on DWR's Alternative Submittal Website

Registration and login are required to submit an Alternative, but are not required to view submitted information.

NOTE: All information submitted to the Alternative Reporting System website can be viewed by the public.

Adjudicated Basins

The Sustainable Groundwater Management Act asks watermasters or managers of adjudicated areas to submit certain values and documents to DWR by April 1 of each year. (see Water Code section §10720.8) This site was developed to allow watermasters and managers to submit the required information to DWR.

Watermasters and managers of adjudicated areas must establish a secure User ID and Password in order to access the system and submit information. Once submitted, the information for a reporting year is locked. If updates or corrections are necessary, please send an email to Timothy.Ross@water.ca.gov.

NOTE: All information submitted to the Adjudicated Basin Annual Reporting System website can be viewed by the public.
