Each GMA must define its “desired future conditions by 2060” based on actual withdrawal data and projections of groundwater availability. A groundwater management plan must be set accordingly. Water has a higher economic (extractive) value in Region H (Houston area), where water mostly serves municipal and industrial water needs, than in the farming Regions O and A. As a result, the economic cost of unmet water needs (groundwater as well as surface water) is much higher in Region H (Figure C.19).
