Groundwater in Texas

The hydrology of Texas is amazingly complex. Here’s the major aquifers:

There’s a map of minor aquifers too. They can’t easily show them on the same map because of overlaps.

Better version of this map and others are available for the clicking from TWDB


  1. The question is can Texas survive another year of drought on groundwater resources alone? Or two years? Three? Multi-year droughts are pretty common out here in California even with the Sierra Nevada and Cascades acting as a vast water storage banks. I hate think what we'd do without them.

  2. Use an NPP to desalinate sea water and pump it up (horizontally is just small losses). The former will cost about $1.30 per metric tonne and using 250 meters as the elvation, the pumping costs add about $0.82 per tonne to that.Much better than a court case, me thinks.Of course, one has to arrange the approximately $4 billion for the NPP alone, plus the desal plant plus the pumping station(s) and piping or canals. But the mortgage payment involved is supposed to be included in the above costs.
