Minimum Depth to Groundwater for the Coastal San Francisco Bay Area

This dataset shows estimated values for minimum depth to groundwater in the coastal Bay Area. The estimation is based on an interpolation that uses ground elevation data and minimum depth to water values measured at monitoring wells in the nine Bay Area counties over the past 20 years. NOTE: The most recently uploaded data file (August 24, 2018) has the highest accuracy in the interpolation. Please use this file rather than the older versions.
