Basin Notes
2003: Bulletin 118 basin description.
2016: Basin boundary modification approved with Llargas Area 3-003.01 subbasin
2018: Draft Basin Prioritization note: GWLs continued to decline in areas of basin that rely on GW, specifically in the Bolsa, San Juan, Hollister West, Bolsa SE, and Tres Pinos subbasins. While some subbasins showed groundwater level increases, overall groundwater in storage decreased. Groundwater elevation declines and storage decreases during drought do not constitute overdraft; nevertheless, the continued reduced supplies of imported water in tandem with increased groundwater demands are a warning of potential overdraft.

2019: Basin boundary modification approved consolidating the Hollister Area subbasin into the North San Benito Groundwater subbasin (3-003.05)
