Basin Notes
2003: Bulletin 118 basin description Corral de Tierra
2014: CASGEM Basin Prioritization – Medium
2016: Basin boundary modified in relation to the adjudicated neighboring Seaside 3-004.08 subbasin. Per DWR: This request was initially submitted as a jurisdictional subdivision, but was
changed to a scientific external modification based upon the USGS study supporting the adjudication of the Seaside area. The remaining portions of the original Seaside subbasin were incorporated into the Corral De Tierra subbasin due to similar hydrogeologic properties.
2018: Basin priority: High. Prioritization comment: Seawater intrusion began in the Salinas Valley by the 1930s. Since that time, seawater intrusion has continued and now extends more than five miles inland. The Monterey County Flood Control and Water Conservation District built Nacimiento Dam in 1957 and an Antonio Dam in 1965 to provide flood control and to accelerate groundwater recharge to mitigate seawater intrusion. In April 1998, the Monterey County Water Recycling Projects started delivering recycled water for irrigation in lieu of groundwater pumping, effectively slowing the seawater intrusion rate. 2) The Salinas Valley Water Project is currently being implemented by the Monterey County Water Resources Agency to mitigate groundwater overdraft and seawater intrusion. The project includes mitigation measures such as construction or retrofit of recharge dams, protection of recharge areas, and injection of recycled water into the impacted aquifers. Arsenic noted in GAMA study and reported in 9/22/16 Monterey County Weekly
2018: Final Basin Prioritization: Basin status remains unchanged at medium priority.
2022: January 28 – GSP submitted to DWR
2023: April 27 – GSP approved by DWR
