Water Level Monitoring

The OBGMA collects continuous groundwater level and temperature data via data loggers in five production wells and the San Antonio Creek Spreading Grounds depth discrete monitoring well. These data are used by the agency to better understand and manage the basin, such as through the development and calibration of groundwater hydrology models.

VCWPD Monitoring

The Ventura County Watershed Protection  District (VCWPD) collects groundwater level data four times per year from 18 monitoring wells in the basin. Most of the wells monitored are privately owned. Regular monitor­ing by VCWPD began in 2005, though some records go back to the 1950s. The VCWPD produces an annual report summarizing well-monitoring data, well levels, and water quality.
