<br />O~T-16-9a FRI 11:10 UPPER COLORADO RIVER COMM <br /> <br />P _ 15 <br /> <br />000236 <br /> <br />Six State Proposal <br />Straw Man Draft <br />October 13, 1998 <br /> <br />Six States do not believe it is prudent to apply surplus strategies that make additional <br /> <br />water available based on statistical analysis which they believe presents a higher risk, if <br /> <br />the incremental water benefits are likely to be limited to those purposes. The Six State <br /> <br />proposal will make water available for those purposes "in years when the "?OR" strategy <br /> <br />indicates that additional water should be released for beneficial use in lieu of potential <br /> <br />release through the flood control criteria. If incremental surplus volumes are limited <br /> <br />under this tier, priority must be given to groundwater banking for future M&I needs <br /> <br />within California over agricultural uses. Agricultural uses in California should be limited <br /> <br />to those years when the .'70R" criteria results in large surplus volumes and there is a high <br /> <br />degree of certainty that water would otherwise be subject to spill. <br /> <br />S. Flood Control criteria <br /> <br />This tier refers to the current Corps of Engineers criteria for space building in <br /> <br />Lake Mead that is necessary to avoid damaging levels of downstream flood releases. The <br /> <br />flood control criteria is not, per se, a surplus strategy. Rather it is a strategy to use <br /> <br />reservoir space to be able to reduce peak inflows so that outflow rates can be reduced to <br /> <br />non-damaging levels. The surplus strategy relationship develops when the Corps criteria <br /> <br />call for reservoir releases to be made at levels above downstream delivery requirements. <br /> <br />Rather than let that volume be spilled to the Gulf of California, surpluses are declared to <br /> <br />allow increased beneficial use in the Lower .Basin States and Mexico. <br /> <br />14 <br />
