The 1997 Texas Legislature established a state water planning process that assesses conditions in each of 16 regionsidentifies solutions to water shortages and estimates their cost. The Texas Water Development Board (TWDB) synthesizes these plans into a single state plan that estimates the state’s water needs over a 50-year horizon (Exhibit 4).
