Contours of Corcoran Clay Thickness in feet by Page (1986) for the Central Valley Hydrologic Model (CVHM)
This digital dataset defines the thickness of the Corcoran Clay Member of the Tulare Formation. The complex 
hydrologic system of the Central Valley is simulated using the USGS numerical modeling code MODFLOW-FMP 
(Schmid and others, 2006b).  This simulation is referred to here as the Central Valley Hydrologic Model …
