Water Planning

The TGRGCD was created to address groundwater issues or problems within the District overlaying Trinity group of aquifers. The District includes data from the TWDB’s Groundwater Availability Models (GAMs), input from the Groundwater Management Area 9 cooperative planning process, public input, and the most current and accurate site-specific data available in the development of its management plan to preserve, protect and conserve the Aquifer.


The District also cooperates with adjacent groundwater districts, Groundwater Management Area 9, Regional Water Planning Groups, local water purveyors and stakeholders, and adjacent counties with similar aquifers and/or groundwater usage to ensure a collaborative means of protecting water supplies in this area of the state.
