Groundwater Management Area 9 (GMA-9)


Groundwater Management Area 9 (GMA-9) was established in 2002 and includes all or part of 9 counties in the Texas Hill Country. The Texas Water Development Board created 16 Groundwater Management Areas across Texas, each with a number of groundwater conservation districts (GCDs) included in their boundaries. 

GMA-9 member districts meet at least annually to conduct joint planning with the other districts in the management area and to review the management plans, the accomplishments of the management area, and proposals to adopt new or amend existing desired future conditions. The GMA 9 Committee consists of 9 GCDs, each with its own designated representatives serving as a voting member.

You can obtain all GMA-9 planning, meetings and news at:
