<br />~I <br /> <br />. <br /> <br />. <br /> <br />ACCOUNTING FOR STORAGE OF SAVED WATER <br />UNDER THE METROPOLITAN WATER DISTRICT OF <br />SOUTHERN CALIFORNIA/PALO VERDE IRRIGATION DISTRICT AGREEMENT <br /> <br />The Metropolitan Water District of Southern California (MWD) and the Palo Verde <br />Irrigation District (PVID) have recently entered into an agreement whereby MWD <br />will pay PVID farmers to leave land fallow (idle) in return for the water saved <br />by not irrigating the land. The program will run for 2 years, with estimated <br />water savings of 100,000 acre-feet per year, for a total of 200,000 acre-feet. <br />MWD will be allowed to store the saved water in Colorado River system storage in <br />the lower basin. <br /> <br />The actual water savings to be achieved by leaving PVID farmland fallow is <br />estimated to be 5.1 acre-feet per fallowed acre per year. However, to cover <br />potential evaporation loss while in storage, to develop benefits to <br />Colorado River system storage, and to facilitate administration of the water <br />saving program, the value used in accounting for the water will be 4.6 acre-feet <br />per fallowed acre per year, less any water applied to the fallowed land for dust <br />control. <br /> <br />If the saved water is used by MWD in the same year it is saved, it will be <br />accounted as consumptively used as a part of California's apportionment for that <br />year. <br /> <br />Any water saved during a year, which is still in storage at the end of the , ' <br />calendarfi1ear, will be recorded as saved and stored to the credit of MWD in that <br />year. T 1S saved water will also be charged to California's 4.4 million <br />acre-foot (maf) basic apportionment for that year, and will therefore reduce, by <br />the saved amount, the water available for consumptive use pursuant to that <br />4.4 maf basic apportionment, and consequently the water available pursuant to the <br />7.5 maf basic apportionment of the lower basin. A specific accounting of water <br />saved and stored under the MWD/PVID Agreement will be maintained in the <br />compilation of records kept in accordance with Article V of the Supreme Court <br />Decree (Article V records), as illustrated on the selected pages of the November <br />estimate of 1992 yearend water use which follows page 2. <br /> <br />When any of the saved water in storage is withdrawn in a later year for use by <br />HWD, it will be recorded as used in the year of withdrawal, but will not be <br />charged to California's or the lower basin's apportionments for that year. In <br />other words, the consumptive use of the saved water will be in addition to, and <br />not part of, California's 4.4 maf basic apportionment or the lower basin's <br />7.5 maf basic apportionment for the year of withdrawal. A specific accounting of <br />withdrawal and use of stored saved water will be kept in the Article V records. <br /> <br />In the event that flood control releases are made which result in excess <br />deliveries to Mexico, saved water in storage will be considered and accounted as <br />released for flood control, up to the amount of saved water in storage or the <br />amount of such excess deliveries to Mexico, whichever is less. <br /> <br />Any saved w~r left in storage on January 1, 2000, will cease to be accounted as <br />saved water,~nd will become system water. <br />~ <br />~\ <br />
