The construction of a reservoir lake was proposed in 2010 for George County, Mississippi, USA. The proposed reservoir would be designed to serve primarily for industrial water storage. As the preliminary portion of the reservoir project, a baseline watershed assessment was performed for the purpose of identifying a reservoir site with potential to fill a lake volume capable of providing a sufficient water supply to prevent the Pascagoula River near Graham Ferry, Mississippi from dropping below a measured 7Q10 base flow when 100 million gallons of water per day are withdrawn from the river for industrial use. The initial focus of the assessment was on three watersheds Big Creek, Big and Little Cedar Creek, and Escatawpa River. Evaluations of surface water quantity and quality measurements along with reservoir daily water storage models suggested two reservoirs were suitable for continuation of the reservoir project.
