Bulletin 118: California’s Groundwater (1975)

Water has long been a key factor in California’s social and economic development.  The water has come about equally from groundwater (water stored underground in permeable rock or soil formations) and from surface water.  Although many reports describing the statewide surface resource have been published, very few reports have been devoted to a statewide groundwater appraisal.

This report provides a summary of the vast amount of information available on individual groundwater basins.  It also describes past, present, and possible future management of the groundwater resource.
