Draft GSP Regs Posted

Draft Groundwater Sustainability Plan Emergency Regulations Posted
The legislative intent of the 2014 Sustainable Groundwater Management Act (SGMA) is for groundwater basins in California to be managed and regulated by local public agencies and groundwater sustainability agencies (GSAs). In the basins designated by the Department of Water Resources (DWR) as medium and high priority, local public agencies and GSAs are required to develop and implement groundwater sustainability plans (GSPs) or alternatives to GSPs (Alternatives). Pursuant to Water Code Section 10733.2, DWR is required to draft and adopt emergency regulations for the evaluation of GSPs and Alternatives, the implementation of GSPs and Alternatives, and coordination agreements by June 1, 2016...More Info

SGMA Basin Boundary Regulations
DWR implemented new basin boundary regulations on November 16, 2015. Establishment of the regulations comes well in advance of the January 1, 2016 SGMA deadline, effectively giving local agencies an additional six weeks to prepare their requests for any basin boundary modifications. DWR will accept basin boundary modification requests from January 1, 2016 through March 31, 2016. A copy of the regulations can be found here.

OSWCR: Online System for Well Completion Reports is Ready for Use
OSWCR ("Oscar") allows water well contractors to submit their well completion reports to DWR using a web based system. This replaces the paper-based system used for the last 60+ years. If you are interested in recieveing information about OWSCR, please subscribe to our mailing list to keep up to date on scheduled training sessions... More Info

Groundwater Basin Boundary Assessment Tool
The Department of Water Resources (DWR) has developed a web-based application to inform local agencies and the Public about the existing Bulletin 118 groundwater basins and other relevant data. The Groundwater Basin Boundary Assessment Tool is an interactive map application that allows users to view and overlay numerous map layers important to water planners.

Statewide Advisory on Sealing Materials

Statewide Advisory: Sealing Materials for Water Wells, Monitoring Wells, Cathodic Protection Wells, and Geothermal Heat Exchange Wells
This advisory is to inform well drillers, local enforcing agency staff, and others about important sealing material considerations for well construction (annular seals) and destruction in the unsaturated zone in California. Studies have shown that a sealing material included in the California Well Standards may not perform adequately in the unsaturated zone... More Info

NASA Land Subsidence Report
A new report on subsidence in California's Central Valley, prepared for DWR by NASA's Jet Propulsion Laboratory, was released in August 2015. The report, Progress Report: Subsidence in the Central Valley, California, shows that subsidence rates of up to nearly two inches per month have occurred in some locations within the Central Valley. This report is also posted on the DWR Drought Information Page.

The GIC Interactive Map
In July 2015, DWR released an updated version of its Groundwater Information Center Interactive Map Application, used to view and download selected groundwater data. Fall 2014 and Spring 2015 groundwater level data is now available, and the updated version also contains a new look and some new functionality.


Public Access to Well Completion Reports
In June, 2015 Senate Bill 83 amended California Water Code §13752 to allow public access to well completion reports.  DWR is required to redact personal information from the Well Completion Reports before making them public.  Since there are about 800,000 reports on file with the Department, it will require a significant effort to redact the personal data from all the Well Completion Reports.  DWR is currently developing a process to make well logs publically available online.  Please visit the Well Completions Report page for more information.

Groundwater Sustainability Program
In March, 2015, DWR released the Draft Strategic Plan for the Groundwater Sustainability Program.

For more information visit the Sustainable Groundwater Management Program website.

Water Management Planning Tool
In February 2015, DWR released its new Water Management Planning Tool to view boundaries important to water planners. The Department intends to test the Water Management Planning Tool internally while also providing a beta version to the public.

New Groundwater and Sustainable Groundwater Management websites
As a result of the recent groundwater legislation, DWR has created two new websites relating to groundwater: "Groundwater" and "Sustainable Groundwater Management". The new DWR Groundwater website provides a central hub to California's major groundwater programs that DWR is responsible for, including Sustainable Groundwater Management, California Statewide Groundwater Elevation Monitoring (CASGEM), and Bulletin 118. The new DWR Sustainable Groundwater Management website provides information related to DWR's new Sustainable Groundwater Management Program.

Prioritization Map

Initial Groundwater Basin Prioritization under the Sustainable Groundwater Management (SGM) Act
The SGM Act directs DWR to develop the initial groundwater basin priority by January 31, 2015. DWR has concluded that the basin prioritization finalized in June 2014 under the California Statewide Groundwater Elevation Monitoring (CASGEM) program will be the initial basin prioritization. The SGM Act applies to the 127 High and Medium priority groundwater basins, which account for approximately 96 percent of groundwater use in California. Read more here...

Public Update on Groundwater Conditions
On November 25, 2014, DWR released the Drought Response report as required by the Governor's April 2014 Proclamation of a Continued State of Emergency. The report identifies groundwater basins with potential water shortages, gaps in groundwater monitoring, and includes a summary of land subsidence monitoring and agricultural land fallowing. Information regarding current drought conditions and DWR's drought response efforts is available at the DWR Drought Information website.

2014 Land Subsidence Report
The report summarizes recent and historical land subsidence and estimates the potential for future subsidence within the DWR Bulletin 118-defined groundwater basins of California. Information contained in the report is also available on the Groundwater Information Center Interactive Map Application.

Groundwater Conditions Report
On April 30th, 2014, a Drought Response report was completed by DWR and delivered to the Governor's office as required by the Governor's Drought Declaration (January, 2014). High-resolution figures from this report are available in the Groundwater Data Reports section of the Groundwater Information Center.

Contractors State License Board Licensed Well Drillers List
The Governor’s Drought Task Force has identified existing resources available to consumers whose groundwater wells have gone dry due to the drought. Because of this and other drought-related impacts, the Contractors State License Board (CSLB) is expediting C-57 applications. Any contractor hired to drill a well in California is required to possess a valid C-57 Water Well Contractor's License issued by the CSLB. Licenses from other states are not valid in California. Consumers can check the status of a contractor’s license and get more information on hiring a contractor at or by calling 1-800-321-CSLB (2752). Well construction also requires permits from the local permitting agency. Click here for more information about well permitting agencies.
