Groundwater Management Areas
Groundwater Management Areas (GMA’s) 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. To the extent feasible, the groundwater management areas coincide with the boundaries of a groundwater reservoir or a subdivision of a groundwater reservoir. There are 16 Groundwater Management Areas in Texas. For a map showing the Groundwater Management Area locations click here: . The Gonzales County Underground Water Conservation District is located in GMA 13, along with eight other groundwater districts.

Region L Water Plan
Each Regional Water Planning Group (RWPG) is responsible for preparing and adopting a regional water plan for its area which is then incorporated into the State Water Plan. The Gonzales County Underground Water Conservation District is located in the South Central Texas Regional Water Planning Group (Region L). RWPGs must provide a process for public input in the planning process, hold public meetings, and furnish a draft report of the plan for public review and comment. The Texas Water Code requires that regional and the State Water Plans be updated every five years.

State Water Plan
This plan presents information regarding the recommended conservation and other types of water management strategies that would be necessary to meet the state’s needs in drought conditions, the cost of such strategies, and estimates of the state’s financial assistance that would be required to implement these strategies.
