Coastal Bend Regional Water Plan September 2010 A-4 Appendix B Summary of Phase I Studies HDR-007003-10661-10 Appendix B Study 1 - Evaluation of Additional Potential Regional Water Supplies for Delivery through the Mary Rhodes Pipeline, Including Gulf Coast Groundwater and Garwood Project This study: (1) included an evaluation of water quality of potential new supplies, (2) identified potential blending and water chemistry issues, and (3) considered reservoir system operations with possible future supplies from the Gulf Coast Aquifer, Garwood project supplies for two delivery scenarios around and through Lake Texana, and additional Lake Texana water supplies as may be available through projects being considered by the Lavaca-Navidad River Authority. A modified version of the Corpus Christi Water Quality and Treatment Model was utilized to analyze water quality and treatment requirements when blending different water sources. The model was developed to simulate treatment processes currently utilized at the O.N. Stevens Water Treatment Plant (WTP). Five blending scenarios were evaluated. The blending analysis did not indicate any large treatment issues at the O.N. Stevens WTP when blending groundwater supplies from the Gulf Coast Aquifer, surface water supplies from the Garwood Project, or additional supplies from Lake Texana with existing supplies from the Nueces River and Lake Texana. The Corpus Christi Water Supply Model (CCWSM) was then used to evaluate various reservoir system operations and delivery scenarios with potential new supplies delivered through the MRP. System operations for five different combinations of existing and potential future water supplies through the MRP were simulated using the CCWSM at a fixed demand of 175,000 acft/yr. The five operating scenario combinations considered current and potential future water supplies for delivery through the MRP and, on average, the amount of MRP capacity in use ranged from 47% to 100%. Essentially, as more water supplies are available for delivery through the MRP, the supplies needed from the Choke Canyon Reservoir and Lake Corpus Christi (CCR/LCC) System decreases for a fixed demand. This results in more water stored in the CCR/LCC System, which increases reservoir pass-thrus of freshwater for the Nueces Bay and Estuary according to provisions of the 2001 Agreed Order. The results from this study were considered during the update of the Gulf Coast Aquifer Supplies water management strategy (see Section 4C.07) and the Garwood Pipeline Project (see Section 4C.14). Coastal Bend Regional Water Plan September 2010 B-1 HDR-007003-10661-10 Appendix B Study 2 – Optimization and Implementation Studies for Off-Channel Reservoir The 2006 Coastal Bend Regional Water Plan (2006 Plan) and the 2007 State Water Plan included the Nueces Off-Channel Reservoir (OCR) near Lake Corpus Christi as a recommended future water management strategy for the Coastal Bend Region to meet needs by Year 2040. Federal interests are studying opportunities for flood damage reduction, ecosystem restoration, and/or water supply benefits in South Texas. During the 2007 Texas legislative session, the Nueces Off-Channel Reservoir site was designated as one of 19 unique reservoir sites in the State of Texas. The Texas Water Development Board (TWDB) Reservoir Site Protection Study1 recommended the Nueces Off-Channel Reservoir as one of the top-ranked sites in Texas for protection or acquisition. The OCR is a water management strategy that could be used to (1) enhance the system yield of Choke Canyon Reservoir (CCR) and Lake Corpus Christi (LCC), (2) capture water that would otherwise spill from LCC, and
