Semi-Annual Groundwater Reports

Since the Fall of 1971, the San Joaquin County Flood Control and Water Conservation District (District) has monitored groundwater levels and groundwater quality throughout San Joaquin County and has published the data in the Semi-annual Groundwater Report . This report utilizes data from Federal, State and local government agencies as well as non-governmental sources.

The San Joaquin County Groundwater Data Center (GDC) is a Countywide centralized groundwater information vehicle that provides access to groundwater data collected and shared by agencies throughout San Joaquin County. Over the internet, water interests including groundwater users, Basin stakeholders, industry professionals, decision makers, and the general public will be able to access historic groundwater data.
