Contours of Corcoran Clay Depth in feet from Page (1986) for the Central Valley Hydrologic Model (CVHM)
This digital dataset defines the depth 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 …
