Groundwater Management Areas

Groundwater Management Areas were created "in order to provide for the conservation, preservation, protection, recharging, and prevention of waste of the groundwater, and of groundwater reservoirs or their subdivisions, and to control subsidence caused by withdrawal of water from those groundwater reservoirs or their subdivisions, consistent with the objectives of Section 59, Article XVI, Texas Constitution, groundwater management areas may be created..." (Texas Water Code §35.001) Added by Acts 1995, 74th Leg., ch. 933, §2, eff. Sept. 1, 1995.

The responsibility for Groundwater Management Area delineation was delegated to the Texas Water Development Board. (Section 35.004, Chapter 35, Title 2, Texas Water Code)

The initial Groundwater Management Area delineations were adopted on December 15, 2002, and are modified as necessary according to agency rules. (356.21, TWDB Rules)

Summary of the Management Plan Components

Here is a spreadsheet summary of the management plan components for all groundwater conservation districts in the state. The spreadsheet was prepared by the Groundwater Division staff to facilitate joint planning efforts in the groundwater management areas and is updated quarterly. There is a summary page that provides information for all of the groundwater conservation districts. Plus there are individual tabs corresponding to each GMA for ease of reference.
