<br />16 <br />Typically, by the end of July, the reservoir is approaching its highest level of the year. <br />Figures 9 and 10 show the same relationships as Figures 7 and 8, only for reservoir elevations at <br />the end of July. Inspection of these figures shows again that the occurrences of elevations at the <br />end of July that were below 6000 feet above sea level increased significantly when the model <br />achieved the 18,600 cfs objective, The Action(ALL-I) occurrences when elevations at the end of <br />July were below 6000 were about 20 (>1% of the time). The Action(ALL) occurrences for this <br />same classification were nearly 300 (12% of the time), The No Action model run had no <br />occurrences where elevations at the end of July were below 6000, <br /> <br />Table 2 shows the exceedance percentage values for all February and July elevations for <br />the Action(ALL and ALL-I) and No Action results. The results in Table 2 indicate that the <br />"most likely" (50% exceeclance) reservoir elevations at the end of February for the Action(ALL- <br />I) model run were be about 2 fef?t lower than the No Action model run, The "most likely" end of <br />July elevations had a difference of nearly 4 feet for the Action(ALL-I) and NoAction rolesets. <br />Similar comparison between the Action(ALL) roleset and the NoAction rolesets shows that the <br />"most likely" end of February elevations were about 5 feet lower for the Action(ALL) then the <br />NoAction ruleset. The July elevation difference was about 7 feet. <br /> <br />TABLE 2 Percental!e Exceedance Februarv/Julv Elevations <br />Percentage Action (ALL-I) Action (ALL) No Action <br />Exceedance (Feet above Sea Level) (feet above Sea Level) (Feet above Sea Level) <br />90% 6016.4/6019.2 5992.9/5997.2 6020.1/6021.4 <br />80% 6020.116023.6 6013.7/6015.7 6024.7/6024.1 <br />70% 6022.5/6026.4 6017.7/6020.3 6026.3/6026.7 <br />60% 6024.0/6028.0 6020.0/6023.5 6026.9/6028,7 <br />50% 6025.1/6029.1 6022.0/6026.0 6027.0/6032.8 <br />40% 6025.9/6030.3 6024.2/6027.9 6027.2/6033.9 <br />30% 6026.3/6030.7 6025.5/6029.3 6027.3/6034.9 <br />20% 6026.6/6031.2 6026.2/6030.8 6027.5/6036.1 <br />10% 6027.0/6032.1 6026.8/6031.8 6027.7/6038.0 <br /> <br />Figures II and 12 show the complete distribution of the February and July elevations that <br />were predicted for the three model runs. For reference, historic elevations for the period from <br />1971 through 1991 have been included on the figures, <br />
