The discharge of Wellton-Mohawk drainage above Morelos Dam is to be coordinated, insofar as practicable, with Mexico's scheduled deliveries in order to minimize the salinity of its irrigation water. The International Commission will keep the operation continually under review. Both Governments reserve all legal rights. Essentially, the proposed works would be operated so as to discharge the most highly saline drainage water from the Wellton-Mohawk district below Mexico's principal diversion point during the winter months when irrigation requirements in the Mexicali Valley are at their lowest. During this period, this would be accomplished by pumping the most saline drainage water into the extension channel for discharge below Morelos Dam. At other times, when Mexico schedules increased deliveries of irrigation water, drainage water would be pumped from the less saline wells in the Wellton-Mohawk district so that most or all of it may be discharged from the extension channel into the Colorado above Morelos Dam. There it would mingle with other Colorado River flows and be diverted by Mexico for irrigation.
