Why was the Prairielands GCD created?

The Prairielands GCD was created in response to a finding by the Texas Commission on Environmental Quality that groundwater shortages were expected in Ellis, Hill, Johnson, and Somervell counties over the next 25 years.  The TCEQ finding required local residents to create a groundwater conservation district, or else TCEQ would mandate one.  Enabling legislation for the Prairielands GCD was passed in 2009.
