1 <br />January 7, 2004 29 <br />Division States beyond a Full Domestic Surplus. The notation 70R refers to the natural inflow into <br />Lake Powell that has been exceeded 30 percent of the time (17.4 maf). <br />' As provided in Section 3 of the Interim Surplus Guidelines, the Secretary shall undertake a "mid -year <br />review" pursuant to Article I(2) of the Operating Criteria, allowing for the revision of the current <br />AOP, as appropriate, based on actual runoff conditions which are greater than projected, or demands <br />' . which are lower than projected. The Secretary shall revise the determination for the current year <br />only to allow for additional deliveries. Any revision in the AOP may occur only after a reinitiation <br />of the AOP consultation process as required by law. <br />' 1944 U.S.-Mexico Water Treaty <br />' Under most probable inflow conditions, water in excess of that required to supply uses in the United <br />States will not be available, therefore there will be no Colorado River Surplus, as defined by the <br />1944 U.S.- Mexico Water Treaty, for delivery to Mexico. Vacant storage space in mainstem <br />' reservoirs is substantially greater than that required by flood control regulations. Therefore, a <br />volume of 1.5 maf (1,850 mcm) of water will be available to be scheduled for delivery to Mexico <br />' during calendar year 2003 in accordance with Article 15 of the 1944 U.S.- Mexico Water Treaty and <br />Minute No. 242 of the International Boundary and Water Commission. Calendar year schedules of <br />the monthly deliveries of Colorado River water are formulated by the Mexican Section of the IBWC <br />' and presented to the United States Section before the beginning of each calendar year. <br />The International Boundary and Water Commission concluded Minute No. 310 entitled "Emergency <br />' Delivery of Colorado River Water for Use in Tijuana, Baja California," on July 28, 2003. The <br />Minute allows for the delivery of approximately 1,200 acre -feet per month of Colorado River water <br />through the California agencies' distribution system facilities to Tijuana, Baja California. In <br />conformance with the provisions of the Minute, the volume of water delivered and the system <br />conveyance losses will be charged against the total volume of Colorado River water apportioned <br />under the 1944 U.S.- Mexico Water Treaty. The Tijuana utility, CESPT, pays all financial costs <br />' . incurred in making such deliveries. This arrangement will be implemented via an agreement among <br />the Otay Water District, the Metropolitan Water District of Southern California, the San Diego <br />t County Water Authority, the United States Section of the International Boundary and Water <br />Commission, and the Bureau of Reclamation and will be applicable through calendar year 2008. <br />l <br />n <br />u <br />
