About the Ojai Basin
The OBGMA is responsible for managing the Ojai Valley Groundwater Basin. The basin is bounded on the west and east by
nonwater-bearing Tertiary age rocks, on the south by the Santa Ana fault and the Sulphur Mountain Range, and Black Mountain and on the north by the Topatopa Mountains. The basin is drained by Thacher and San Antonio Creeks to the Ventura River. Average annual precipitation ranges from 20 to 24 inches. In order to carry out its mission of preserving the quality and quantity of the groundwater the OBGMA must have a comprehensive understanding of the hydrology of the basin obtained through Monitoring, Data Collection, Well Registration and Extraction Measurement.
