<br />will undertake enforcement actions consistent with the Decree to ensure that no Colorado River <br />water user(s) exceeds its lawful use in CY 2003. <br /> <br />For informational purposes, the natural inflow required to reach a Quantified Surplus (70R value <br />strategy) on January 1,2003, is 34.9 maf(43,049 mcm), which has been exceeded in the historical <br />record less than 1 percent of the time. As provided in Article IV(l) of the Interim Surplus <br />Guidelines, the 70R strategy involves assuming a 70-percentile inflow into Lake Powell, subtracting <br />out the consumptive uses and system losses and checking the results to see if all of the water could <br />be stored or if flood control releases from Lake Mead would be required. If flood control releases <br />from Lake Mead would be required, additional water is made available to the Lower Division states <br />beyond a full domestic surplus. The notation 70R refers to the natural inflow into Lake Powell that <br />has been exceeded 30 percent of the time (17.4 mat). <br /> <br />On June 19,2002, Reclamation published a Federal Register notice (67 FR 41733) stating the <br />Secretary would be accepting input on the following: <br /> <br />(1) The ability oflower basin entities outside of California to affect compliance with section <br />5(B) requirements, <br />(2) the need of other lower basin entities outside of California, to utilize surplus quantities in <br />2003 (and the relative amounts of such surplus quantities), <br />(3) impacts on storage of water in the Colorado River reservoirs, and the impact on future <br />deliveries to users of the waters of the Colorado River under applicable provisions of <br />federal law and international treaty, and <br />(4) impacts on California's ability to meet applicable conditions for reinstatement of the <br />determinations under sections 2(B)(1) and 2(B)(2). <br /> <br />In response to this Federal Register Notice, Reclamation has received comments and is continuing to <br />review the issues identified in the notice. <br /> <br />As provided in Section 3 of the Interim Surplus Guidelines, the Secretary shall undertake a "mid- <br />year review" pursuant to Article 1(2) of the Operating Criteria, allowing for the revision of the <br />current AOP, as appropriate, based on actual runoff conditions which are greater than projected, or <br />demands which are lower than projected. The Secretary shall revise the determination for the current <br />year only to allow for additional deliveries. Any revision in the AOP may occur only after a <br />reinitiation of the AOP consultation process as required by law. <br /> <br />1944 U.S.-Mexico Water Treaty <br /> <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 ofthe International Boundary and Water Commission.
