The passage of the Sustainable Groundwater Management Act (SGMA) in 2014 set forth a statewide framework to help protect groundwater resources over the long-term. SGMA requires local agencies to form groundwater sustainability agencies (GSAs) for the high and medium priority basins. GSAs develop and implement groundwater sustainability plans (GSPs) to avoid undesirable results and mitigate overdraft within 20 years. GSP boundaries are managed through the SGMA Portal. This dataset represents the current GSP boundaries and includes attributes such as GSP manager contacts and GSP status. The GSP submission process is completed via the SGMA Portal and includes two primary steps: 1) a GSA(s) submits a GSP, and all associated documents and data, to the SGMA Portal’s GSP Reporting System; and 2) the Department conducts an acceptance review and posts accepted GSPs to the SGMA Portal. A single GSP, or multiple GSPs with a Coordination Agreement, must cover an entire basin or subbasin, and can only be submitted once adopted by the underlying GSA(s). GSPs are submitted in the format required by 23 CCR §353.2 and 23 CCR §353.4 of the GSP Regulations and includes the shapefiles associated with this dataset. The Department of Water Resources (DWR) must complete the acceptance review within 20-days following the submission of a GSP. During the acceptance review, DWR verifies that the GSP submission demonstrates that the GSP was adopted, covers the entire basin or subbasin, and contains all required documents and data. If DWR accepts the submitted GSP, it is then posted to the SGMA Portal, and then a public comment period is opened.
