Groundwater Management Area 2 (GMA 2) is one of 16 groundwater management areas in Texas. It covers a large portion of the South Plains region of Texas.

The process of adopting a Desired Future Condition (DFC) was established by the Texas Legislature in 2005 and requires groundwater conservation districts within their respective GMA to establish DFCs for relevant aquifers at least once every five years.

Texas Water Code § 35.001 states that groundwater management areas may be created “to provide for the conservation, preservation, protection, recharging, and prevention of water of the groundwater, and of groundwater reservoirs or their subdivisions.”

GMA 2 Process

The Desired Future Conditions (DFC) process is a vital part of the state’s overall water planning.

  • All groundwater conservation districts (GCDs) in a groundwater management area (GMA) must meet at least annually for joint planning purposes.
  • Desired Future Conditions (DFCs) are developed during the joint planning process. This results in a “big picture plan” for future aquifer conditions.
  • Groundwater levels, amount of groundwater in storage, desired spring flow, or base flow to rivers and streams are all factors that can be considered in setting DFCs.
  • After the DFC is determined, the proposed DFC and supporting data are sent to the Texas Water Development Board (TWDB) in Austin.
  • TWDB staff translate the DFC into an estimate of the amount of managed available groundwater (MAG).
  • Regional Water Planning Groups use the area’s MAG to evaluate potential needs of water user groups during a 50-year planning horizon.


Representatives of Groundwater Management Area 2 adopted the proposed desired future conditions at their March 25, 2021 virtual meeting.

  • A GMA 2-wide average drawdown of 28 feet between 2013 and 2080 for the Ogallala and Edwards-Trinity (High Plains) Aquifers.
  • A GMA 2-wide average drawdown of 31 feet between 2013 and 2080 for the Dockum Aquifer.

The process of adopting a DFC was established by the Texas Legislature in 2005 and requires groundwater conservation districts to establish DFCs for relevant aquifers at least once every five years.

Ogallala Aquifer

  • The major aquifer in GMA 2.
  • Groundwater in the Ogallala Aquifer in the Texas Panhandle flows from northwest to southeast at about 100 to 150 feet per year under natural conditions.
  • The amount of water bearing material (“saturated thickness”) can vary greatly—depending upon the spatial arrangement of rivers and valleys when the sediments were deposited. Because of this, the saturated thickness of the aquifer in GMA 2 can change over a very short distance.
  • Playa lakes that fill with rainwater are primary recharge points for the Ogallala Aquifer in GMA 2.
  • Estimated recharge to the Ogallala Aquifer in GMA 2 can vary from 1/4 inch to 2 ¼ inches per year.
