Abstract: An irrigation district on the westside of the San Joaquin Valley of California was used to demonstrate a method for selecting areas for improved irrigation and drainage water management. Improved management should result in reduced drainage water volumes and salt load in surface water. Factors considered included area drained, total drainage flow, irrigation efficiency, and salt load per unit area. The factors were used to rank each sump and then to calculate a composite value for the final rankin g. The results demonstrated that no single factor dominated.
