What is the timeline for GSP submittal?

The process is continuous and will be ongoing over at least the next 50 years. In terms of next steps, the GSPAC will make their recommendation on the draft GSP in October. The Groundwater Sustainability Agency (GSA) will adopt the GSP in December 2021. The Napa Valley Subbasin is a high priority subbasin and the GSP must be submitted to DWR by January 31, 2022. DWR has two years to conduct their review. SGMA Annual Reports are due to DWR every April 1; the next Annual Report is due April 1, 2022. The next GSP update will be due in 2027.
