The <br /> <br />validity of this method is based on the assumption that the mix of uses at the <br /> <br />priority margin is similar to the average. <br /> <br />Upper Basin demands were satisfied before any system reservoirs and Lower <br /> <br />Basin demands, but were subordinate to the Lee Ferry delivery obligation. <br /> <br />Demands in the Lower Basin were given priorities which reflect the U.S. <br /> <br />Supreme Court decision in Arizona v. California (1968). California's 4.4 MAF of <br /> <br />high-priority consumption and Arizona's non-CAP consumption were satisfied <br /> <br />first. CAP was satisfied next, and California's "excess" consumption (above the <br /> <br />4.4 MAF level) was satisfied last. If there was excess water supply to the <br /> <br />Lower Basin (if the Mead flood control pool was not empty), then the excess <br /> <br />California uses were satisfied. Note that the Secretary of the Interior has the <br /> <br />authority to declare a surplus at Lake Mead which allows the MWD excess demand <br /> <br />to be satisfied from the Mead Conservation pool. This was not simulated in the <br /> <br />model. <br /> <br />Nodes 29 and 30 (see Table 111-3) represent M&1 and agricultural demands <br />respectively, located along the Colorado River in Arizona and Nevada. Node 31 <br /> <br />represents both agricultural and M&1 uses supplied by the CAP. Node 32 <br /> <br />represents California agricultural uses (largely Imperial Valley, but also along <br /> <br />the main stem). Node 33 represents the Los Angeles Metropolitan Water District <br /> <br />demands. Demands at Nodes 32 and 33 total to 4.4. MAF, California's high- <br /> <br />priority entitlement as set by Arizona ~ California -- Node 34 represents <br /> <br />demands in the metropolitan Los Angeles area which are in excess of the high- <br /> <br />priority entitlement. These demands have the lowest priority in the Lower <br />
