POPULATION AND WATER DEMANDS Approximately 26 percent of Texas’ population resided in Region C in the year 2010. By 2060, the population of the region is projected to grow 96 percent to 13,045,592. Projections indicate that by 2060 Region C water demands will increase 86 percent (Table C.1). Municipal demands are projected to increase by 91 percent by 2060 and will account for 88 percent of the total projected Region C demands. With the exception of livestock demands, which remain constant, all categories of water demands are projected to increase over the planning horizon (Table C.1, Figure C.2). EXISTING WATER SUPPLIES The total water supply in Region C is projected to decline by about 3 percent by 2060 (Table C.1, Figure C.2). This projected decline is due to reservoir sedimentation. Existing reservoirs within Region C are projected to provide nearly 58 percent of total water supplies in the region, while surface water supplies located outside of the region account for another 22 percent. Groundwater from the Trinity Aquifer and several minor aquifers provides approximately 7 percent of supplies. Currently authorized reuse provides 10 percent of the available supply to Region C. The remaining 2 percent of the water supply comes from local sources, such as run-of-river permits. NEEDS The majority of water supply needs in Region C are for municipal uses (Table C.1, Figure C.2). By 2060, water supply needs in the region are projected to total 1,588,236 acre-feet. Ninety-two percent of this projected need (1,459,025 acre-feet) is for municipal users and county-other. RECOMMENDED WATER MANAGEMENT STRATEGIES AND COST Region C considered a variety of water management strategies to meet needs. In all, the strategies provide an additional 2.4 million acre-feet by 2060 (Figures C.3 and C.4), with a total capital cost of $21.5 billion (Appendix A) if all the recommended water management strategies are implemented. The plan recommends four new major reservoirs: Lower Bois d’Arc, Ralph Hall, Marvin Nichols, and Fastrill Replacement Project. CONSERVATION RECOMMENDATIONS Conservation strategies account for approximately 12 percent (290,709 acre-feet) of the total volume of water associated with all recommended strategies. A basic conservation package, including education, pricing structure, water waste prohibitions, water system audits, and plumbing code changes, was recommended for all municipal water user groups in Region C. An expanded conservation package, including additional strategies such as landscape irrigation restrictions and residential water audits, was recommended for some municipal water user groups. 46 Chapter 2: region C summary WAT E R FOR TEXAS 2012 STATE WATER PLAN
