The estimated amount of additional <br />mainstream water made available in the 2002 AOP was 0.640 maf (789 mcm). A volume of 1.5 maf <br />(1,850 mcm) of water was scheduled for delivery to Mexico in accordance with Article 15 ofthe <br />1944 U.S.-Mexico Treaty and Minute No. 242 of the International Boundary and Water <br />Commission. <br /> <br />Lake Mead began water year 2002 at elevation 1,177.96 feet (359.04 meters), with 19.9 maf (24,546 <br />mcm) in storage, 77 percent of the conservation capacity of25.877 maf(31,919 mcm). During the <br />year, Lake Mead steadily declined and reached its minimum elevation of 1155.42 feet (352 meters) <br />at the end of September 2002, with 17.1 maf(21,093 mcm) in storage, 66 percent of capacity. <br /> <br />The total release from Lake Mead through Hoover Dam during water year 2002 was 10.5 maf <br />(12,951 mcm), with an additional 0.282 maf (348 mcm) being diverted from Lake Mead by the <br />Robert Griffith Water Project. <br /> <br />(1) May be exceeded during beach/habitat building flows, habitat maintenance flows, or when <br />necessary to manage above average hydrologic conditions. <br /> <br />(2) Daily fluctuations limit is 5,000 cfs (141.6 cms) for months with release volumes less than <br />0.600 maf(740 mcm); 6,000 cfs (169.9 cms) for monthly release volumes of 0.600 to 0.800 maf <br />(740 to 987 mcm); and 8,000 cfs (226.6 cms) for monthly volumes over 0.800 maf (990 mcm). <br /> <br />December 13,2002 <br /> <br />16 <br />
