Sustainable Management Criteria Public Meetings

The Department of Water Resources Sustainable Groundwater Management Program will host three public meetings in December introducing its newest Best Management Practice (BMP) publication,
Sustainable Management Criteria (SCM). This BMP characterizes the relationship between the different sustainable management criteria – the sustainability goal, undesirable results,

minimum thresholds, and measurable objectives – and describes best management practices for developing these criteria as part of a Groundwater Sustainability Plan (GSP). This BMP does not impose new requirements, but describes best management practices for satisfying the requirements of SGMA and the GSP Regulations.

Local agencies and interested parties are encouraged to attend and provide comments on the SMC BMP. You may fill out a comment card and turn it in at the event, email your comment to: Subject: Comments on Draft SMC BMP, or comment by US Postal Service to:
P.O. Box 942836
Sacramento, California 94236-0001
Attn: Lauren Hersh, Rm 201.

The public comment period ends January 8, 2018.
Comments received by DWR on the Sustainable Management Criteria Best Management Practices are posted on DWR’s Public Comments – Best Management Practices webpage.

Basin Boundary Modifications Requests – 2018 Schedule

The Sustainable Groundwater Management Act (SGMA) established a process for local agencies to request DWR to review and revise boundaries of existing groundwater basins or subbasins, including establishing new subbasins. The initial round of basin boundary modifications was conducted in 2016 with results published in California’s Groundwater – Bulletin 118, Interim Update 2016. More information on basin boundary modifications, including the Basin Boundary Assessment Tool and the Basin Boundary Modification Request System can be found online at GSAs and local agencies are encouraged to reach out to DWR for assistance with this process. All information to support a boundary modification should be submitted to the Basin Boundary Modification Request System.


    • January 1, 2018: Submission Period opens for 6 months. During this window, GSAs and local agencies can submit the required information to support a Basin Boundary Modification on the SGMA Portal
    • June 30, 2018: Submission Period Closes and 30-day Public Comment Period Opens
    • July 30, 2018: Public Comment Period Closes
    • Fall 2018: Draft Basin Boundary Modifications Released
    • Fall/Winter 2018Final Basin Boundary Modifications Released

Draft Guidance Documents for Engagement and Communication

DWR’s draft guidance documentsGuidance Document for Groundwater Sustainability Plan (GSP) Stakeholder Communication and Engagement (C&E) and Engagement with Tribal Governments are being finalized. The C&E document offers guidance on communication with stakeholders for GSP development through a transparent and inclusive process. The Engagement with Tribal Governments document is intended to help local agencies engage with Tribal Governments in the planning, financing and management of a GSA, or with the development and implementation of a GSP. Public comments received during the public comment period are taken into consideration as DWR prepares the final versions of these guidance documents. The public comment period closed August 28th, 2017.

Data, Tools, and Reports

From datasets to groundwater – surface water models, the Department of Water Resources (DWR) is providing technical assistance to help Groundwater Sustainability Agencies (GSAs) develop Groundwater Sustainability Plans (GSPs), and implement the requirements of the Sustainable Groundwater Management Act (SGMA). The SGMA Technical Assistance Factsheet enables users to find links to technical resources, available on DWR’s SGMA Program – Data, Tools, and Reports webpage including:

· Statewide Data Platforms

· Interactive Maps

New - The California DWR Land Use Viewer, allows GSAs and the public to easily access both statewide (as recent as 2014 crop data) and existing county land use datasets that have been collected over the last 30 years. The Viewer also includes a variety of tools that will allow users to download and analyze land use data. You may want to access the webinar on YouTube for a demonstration of how to use the Viewer.

New - The Well Completion Report Map Application provides access to statewide Well Completion Reports. Well Completion Reports contain information collected by drillers during the drilling and construction of water wells, including the location, dates of construction, planned use, depth of the well, subsurface geologic units encountered, well construction, and well yield.

·                     Modeling: DWR provides a number of existing integrated hydrologic modeling codes and applications available for use. A summary of these resources is available in the Modeling Tools Fact Sheet, along with FAQs on DWR's Integrated Hydrologic Models and Water Budget Pilot Projects and Integrated Hydrologic Modeling and Water Budgets pertaining to the Sustainable Groundwater Management Act and Groundwater Sustainability Plan Regulations

·                     Climate Change: DWR is providing data, tools, and guidance to assist GSAs with incorporating climate change into their GSPs. This effort leverages previous work done by DWR for the Water Storage Investment Program (WSIP). Please refer to the Climate Change Fact Sheet for more information about what will be provided.

·                     Reports – Best Management Practices, Guidance Documents, Bulletin 118, and Bulletin 160

·                     NEW GSP Initial Notification System (in development) - DWR is currently in the process of developing a new GSP initial notification system for GSAs to use when submitting their intent to develop a GSP in accordance with the GSP regulations (California Code of Regulations, Title 23, Section 353.6). Existing notification that have been provided to DWR and posted on our website ( will be transferred to this new system. DWR will be contacting and assisting GSAs with this transfer process. As soon as the system is operational, GSAs will be required to use the system when submitting future notifications. DWR will provide a user’s demonstration of the system during public meetings tentatively scheduled for December (exact dates and locations will be announced soon). It is anticipated this system will operational in January 2018.

Upcoming Events

SGMA Definitions and Groundwater Glossary
SGMA provided California with a roadmap for sustainably managing our groundwater, and it also came with its own lexicon. Looking for the definition of “Undesirable result” or “De minimis extractor”? It’s right here. Additional important groundwater terms and definitions are included in the Groundwater Information Center's Groundwater Glossary.


DWR photographers and videographers share their amazing talents by making their photographs and videos available to the public. Check out some of these incredible pictures!

Cal Legislature Wants to Tax Drinking Water for First Time in History

by  Chriss W. Street 26 Aug 2017 Newport Beach, CA


The California Legislature is moving for the first time in history to tax every residence and business about a dollar month for drinking water to generate $2 billion over the next 15 years to supposedly clean up contaminated ground water.


Although Senate Bill 623 is titled: “Safe and Affordable Drinking Water Fund,” a coalition of agricultural and environmental lobbyists convinced its author Sen. Bill Monning (D-Carmel) to amend the ground water cleanup bill that has been moving through the Legislature since February, to quietly add a water tax of 95 cents per month on every residence and business. The bill would also tack on $30 million in farm and dairy fees. Read more
