Summary
Mendenhall and others (1916) published depth-to-water data compiled in 1910 for all known wells in the San Joaquin Valley, California. Data for the 3,429 wells having depth-to-water of greater than zero feet were used to construct an interpolated depth-to-water surface for the entire SJV. This map represents groundwater levels in approximately 1910, prior to extensive development of the groundwater system. A depth-to-water contour map with contour lines of 5, 10, 15, and 25 meters below land surface was then drawn from this raster surface.

Purpose
The purpose of this dataset is to represent groundwater levels in the San Joaquin Valley, California in approximately 1910, based on data from Mendenhall and others (1916). A GIS raster of depth-to-water below land surface was interpolated from the point data and is provided.
