More than any other natural resource, water holds the key to our future. Yet scarcity and competition for water, heightened environmental concerns, and the expense of new water-supply development make sound water management increasingly difficult to achieve. Nowhere is this challenge more recognized than in Texas where the state’s population is projected to double in the next 50 years. A corresponding increase in the water needs of communities, while maintaining traditional agricultural and environmental use, has made the need for careful water-management decision-making ever more important. Texas is a vast and diverse state, and water management solutions that are appropriate for one region or locale may not be appropriate for another.
