2014: CASGEM basin prioritization – low. Comments: Sulfate, chloride, fluoride, and TDS concentrations are high for domestic use (DWR 1975). High of boron and TDS concentrations, and high sodium percentage impair groundwater for irrigation use (DWR 1975). 2018: Draft basin priority – very low. Comments:
- 1) CASGEM/WDL/GWIDS: No data or data insufficent to determine GWL status. Source: DWR
- 2) No available documentation on groundwater level decline past or present in the basin
