The Salinas Valley Groundwater Basin includes six subbasins, all of which are subject to SGMA and under the oversight of the Salinas Valley Basin Groundwater Sustainability Agency (SVBGSA):

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).
