SSJID and OID joined forces again to build Melones Reservoir. Melones Reservoir held 110,000 acre feet and could irrigate 144,000 acres of land in both districts. Years later, the federal government took over Melones and greatly increased its capacity. The water storage facility is now known as New Melones Reservoir and allows the two districts rights to the first 600,00 acre feet that flows into New Melones Reservoir each water year.
