Abstract: Severe drought conditions occurred in Texas during the 1990’s and resulted in many water entities being forced to implement rationing programs to balance water demand with available supplies. Subsequently, the 75th Texas Legislature mandated a review of the State’s Water Plan. As irrigation is the largest user of water in the Texas Panhandle, a critical assessment of irrigation water demand estimates was needed. Previously, the Texas Water Department Board (TWDB) had provided these projections, principally through surveys from county and regional Natural Resource Conservation Service (NRCS) personnel. To attain a more localized focus, the state was divided into 16 regions. Each region was charged to review the TWDB estimates, and either accept their statistics or formulate a methodology that would possibly be more realistic in reflecting the irrigation water demands in their region. The Texas Panhandle High Plains area was designated as Region A. It was comprised of the following 21 counties: Armstrong, Carson, Childress, Collingsworth, Dallam, Donley, Gray, Hall, Hansford, Hartley, Hemphill, Hutchinson, Lipscomb, Moore, Ochiltree, Oldham, Potter, Randall, Roberts, Sherman and Wheeler.
