Basin Notes
2018: Basin prioritization comment – 1) CASGEM/WDL/GWIDS: No data or data insufficient to determine GWL status. Source: DWR 2) 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. Source: San Benito County Water District San Benito County Water District annual report Basin boundary modification request pending that, if successful, would consolidate the Bolsa Area 3-003.02, Hollister Area 3-003.03, San Juan Bautista Area Subbasin of the Gilroy Hollister Valley and Tres Pinos Valley 3-025. This would shift supervision of the subbasin to the north central region office.
2019: Basin boundary modification approved, now part of the newly formed North San Benito Groundwater subbasin 3-003.05.
