Data Development

The development of electronic data by the state's 16 Regional Water Planning Groups is a five-year process that involves a coordinated effort between the TWDB, the Planning Groups, and the Planning Groups' contracted consultants. In the first phase of the planning cycle, the TWDB and the Planning Groups, in conjunction with other state agencies, develop population and water demand projections for entities using water in the state.

The Planning Groups then use these projections to develop their regional water plans and their electronic water planning data sets. Further data development by the planning groups includes determining how much water is available from all water sources in the state ("availability"), how much of that water goes to each water-using entity ("supplies"), and, by comparing projected supplies to projected demands, whether each water-using entity will have a potential need for additional supplies in the future ("needs"). The final phase of planning and data development requires the evaluation and recommendation of water management strategies for water users who will have a potential need for additional supply.

After the Regional Water Planning Groups submit their electronic data, TWDB reviews it for quality assurance, standardization, and content. When the Regional Water Plans are approved by the TWDB, the resulting data is stored in a database and the data is published on our website. The electronic data collected from the Regional Water Planning Groups is ultimately used to prepare the state water plan. The current state water plan is Water for Texas: 2022 State Water Plan.
