The Salinas Valley Groundwater Basin includes nine subbasins, six of which fall partially or entirely within the jurisdiction of the SVBGSA within Monterey County:
- 180/400-Foot Aquifer Subbasin
- Eastside Aquifer Subbasin
- Forebay Aquifer Subbasin
- Langley Area Subbasin
- Monterey Subbasin
- Upper Valley Aquifer Subbasin
The Seaside Basin is adjudicated and not subject to SGMA.
In 2020, SVBGSA, in partnership with MCWD GSA and the County of Monterey GSA, completed the GSP for the 180/400-Foot Aquifer Subbasin. In 2022, SVBGSA completed GSPs for its remaining 5 subbasins: the Eastside Aquifer Subbasin, the Forebay Aquifer Subbasin (in partnership with ASGSA), the Upper Valley Aquifer Subbasin, the Langley Area Subbasin and the Monterey Subbasin (in partnership with MCWD GSA).
