To enable effective management of the state’s groundwater resources in areas where critical groundwater problems exist or may exist in the future, the Legislature has authorized the Texas Commission on Environmental Quality (TCEQ or Commission), the Texas Water Development Board (TWDB), and the Texas Parks and Wildlife Department (TPWD) to study, identify, and delineate priority groundwater management areas (PGMAs), and initiate the creation of groundwater conservation districts (GCDs or districts) within those areas, if necessary. “Critical groundwater problems” are defined as shortages of surface water or groundwater, land subsidence resulting from withdrawal of groundwater, or contamination of groundwater.
