Selection of the optimum water supply reservoir from multiple reservoir sites under consideration in a water resource planning study for the Houston Metroplex evaluated hydrology, engineering, and cost information. Application of this marginal cost analysis technique permitted the determination and selection of the most economical or optimum reservoir from multiple reservoir sites. Thirty-three reservoir sites were investigated as potential water supply sources. Of these sites, the Bedias 10-mile site was selected as the optimum reservoir with a yield 78,500 acre-feet per year at a conservation pool elevation of 210 feet, USGS and a project formulation cost of $0.50/1,000 gallons.
