<br />August 19, 1999 <br /> <br />154'Q <br /> <br />Scenario Analysis <br /> <br />In addition to analysis of each alternative on its own, several configurations which utilize a <br />combination of the alternatives will be analyzed. It is anticipated that project reoperation can be <br />combined with many of the other alternatives to meet storage needs. Therefore, project <br />reoperation in conjunction with the other five capital improvement alternatives will be analyzed. <br />In addition, there are several other combinations of alternatives that could combined. It is <br />difficult to develop these combinations until the results of each of the individual alternatives are <br />realized. Therefore, the combinations of capital improvement alternatives will be selected as <br />results become available. <br /> <br />The analysis will be performed using three different methodologies: <br />I. Total storage is increased using a single or combination of alternatives until all <br />storage requirements are satisfied. <br />2. Combinations of alternatives will be analyzed for subsets of the total demands as <br />provided by the SECWCD Storage Study Committee. <br />3. Each alternative will be analyzed to show its cost per acre-foot of yield. A graph <br />can then be developed which shows the incremental cost per acre-foot of storage <br />required from a composite list of the alternatives. <br /> <br />The following scenario combinations have initially been identified for further study in the <br />scenario analysis, although the scenario analysis will not be limited to these combinations. <br /> <br />I) Reoperations + Pueblo Reservoir Enlargement + Turquoise Reservoir Enlargement <br /> <br /> Potential <br />Alternative Capacitv (ac-ft) <br />Reoperations 90,000 <br />Pueblo Reservoir Enlarl!ement 75,000 <br />Turquoise Reservoir Enlargement 9,000 <br />Scenario Total 174.000 <br /> <br />2) Pueblo Res.
