<br />"l <br /> <br />"l <br /> <br />b. Scenari 0 II <br /> <br />.... <br /> <br />.... <br /> <br />Scenario II investigates the benefit of repairing both Santa ~~ria <br />and Continental dams, increasing storage to 43,564 acre-feet in Santa <br />Maria reservoir and to 22,679 acre-fe~t in Continental reservoir. The <br />additional storage reduced the shortage of demand by 80,000 acre-feet <br />during the 31 year period as commpared to the "do-nothing" Scenario I. <br />Th i s represents an average benefi t 01' addi ti onal wa ter of approxima- <br />tely 2,600 acre-feet per year. The benefit of Scenario II is plotted <br />on Figure IV~7. Zero values indicate no net benefit during the year. <br /> <br />.... <br /> <br />'11II <br /> <br />'11II <br /> <br />"" <br /> <br />c. Summary <br /> <br />ii <br /> <br />The benefit of repairing the two dams is 80,000 acre-feet within <br />the 31 year period, an average yearly increase of approximately 2,600 <br />acre-feet. The increased yields are available in only 7 out of the 31 <br />year study period. This is caused by the lack of available irl'igation <br />water during most years and the inability of the reservoir to store <br />water in excess of thei I' restri cted capacity duri ng average or dry <br />years. The benefits accrue during the wet years when full stol'age can <br />be utilized, similar to the past couple of years. These benefits are <br />very conservatively estimated, since they do not include the ~ncanced <br />yield attributable to the operation of the Closed Basin Project and <br />the out-of-priority storage program under the agreement with the State <br />Engineer. <br /> <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br /> <br />!V - 18 <br />
