2018: Draft basin priority – very low. Comments –
- 1) CASGEM/WDL/GWIDS: Longterm hydrographs show groundwater level decline. 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.
