Case Study 2,  Parmer County, Texas, Historical Groundwater 3-D Volumetric Analysis

 
 

case study2

Parmer County located in the Texas Panhandle, is approximately 1,000 square miles and the major aquifer is the Ogallala. Over 750 high quality driller’s reports were evaluated for gravel (dark blue), sand (light blue), caliche (olive green), and clay (yellow) intervals from land surface to base of the well. The red base (clay) in the image is the Dockum Formation.

A porosity value was assigned to each type of lithology. Using the 1958 water level surface, the volume of groundwater in static storage was calculated, 19.6 million acre feet. Using the 2008 water level surface, the groundwater in static storage was calculated, 8.0 million acre feet. The yellow line in the 2008 figure represents the 1958 water level surface.
