While this volume is expected to reduce continuously <br /> <br />over time, it is still a significant amount of water and in the early years of the proposal could easily <br /> <br />exceed the amount of water available from spill avoidance strategies. The six states proposal also <br /> <br />includes a small amount of water for municipal uses in Southern Nevada which are anticipated to <br /> <br />meet Nevada's M&I needs above its basic apportionment of 0.3 maf after about the year 2005. <br />WJ~ - ~, !1/} f::; <br />-~rJtPt11t} '.' <br />1/ S-O ............ ~ - <br />Nov M..o..Q <br />IDg?:> - <br />B. Tiered Surplus Strategy ,/ ~ ~~~ <br /> <br />The Six State proposal for Lake Mead operation, like the California 4.4 Plan proposal, <br /> <br />envisions a tiered water management approach. In order to meet the objective of providing <br /> <br />additional water to MWD and SNW A, Arizona must agree, under certain circumstances, to <br /> <br />temporarily waive all or a portion of its legal entitlement to 46% of any surplus. The Six State <br /> <br />tiered approach allows a demand to be incrementally incIca~cdmet in the Lower Basin based on <br /> <br />designed surplus releases under certain reservoir conditions and anticipated runoff. The tiered <br /> <br />approach steps are summarized as follows: <br /> <br />1. Normal Year <br /> <br />During the period while the proposed te.mponuywterim criteria are in place, <br /> <br />normal years will only-be declared only when available Lake Mead storage is at or below <br /> <br />_ af content (elevation JJ.11L). This represents about 6.5 maf of available storage <br />I/so <br /> <br />10 <br />
