Fox Canyon GMA


Groundwater Management Agency

The Fox Canyon Groundwater Management Agency (FCGMA) manages and protects both confined and unconfined aquifers within all or portions of four groundwater basins underlying the southern portion of Ventura County. The FCGMA is an independent special district, separate from the County of Ventura or any city government. It was created by the California Legislature in 1982 to oversee Ventura County’s vital groundwater resources. The boundary covers 183 square miles, and all lands lying above the deep Fox Canyon aquifer account for more than half of the water needs for over 700,000 residents in the cities of Ventura, Oxnard, Port Hueneme, Camarillo, and Moorpark, plus the unincorporated communities of Saticoy, El Rio, Somis, Moorpark Home Acres, Nyeland Acres, Point Mugu and Montalvo.

Our offices are located in the Water Resources Division Ventura County Government Center Administration Building. For maps and directions to the FCGMA office, click here.
