Groundwater Management Areas are comprised of members from groundwater conservation districts within the GMA boundaries. GMAs determine Desired Future Conditions (DFCs) for the aquifers in the regions that they serve. These DFCs are established at least once every five years. These are incorporated into the Regional Water Plan adopted by the local Regional Water Planning Group. High Plains Water District has counties in both GMA 1 and GMA 2.

There are 16 RWPGs in Texas that are charged with developing and adopting regional water plans every five years. High Plains Water District is included in the Panhandle Regional Water Planning Group (Region A) and the Llano Estacado Regional Water Planning Group (Region O).
