The cost of a 10,000 <br />ac-ft reservoir was developed using the 1986 Hydro-Triad Report. <br />This report displayed three cost estimates for three different <br />sized reservoirs. A curve comparing these costsvs. storage <br />volume was generated (see figure 2). A ratio of costs for the <br />25,240 ac-ft reservoir from the 1986 Hydro-Triad Report and the <br />1992 Appraisal study <br />alternative unit cost estimate <br />was computed. This ratio was <br />applied to the Hydro-Triad <br />curve so that a present day <br />alternative unit cost estimate <br />for a 10,000 ac-ft reservoir <br />could be computed. The <br />resulting $19 million cost was <br />then amortized over a fifty <br />year period with varying <br />interest rates. Figure 3 <br />depicts the annual cost per <br />ac-ft vs annual interest rate. <br />No consideration was made for <br />financial contributions that <br />might be made toward this size <br />reservoir by the Recovery <br /> <br />()fENS CREEt:: <br />It"IOe)(-.a Coct Est IIIIOUl <br /> <br />..., <br /> <br />(;; <br />8 ! <br />~ <br />~ i &:m <br /> <br /> <br />.. <br /> <br />.. <br />- <br />S'rOAAGE V04..\A.E. cae-H) <br /> <br />.........Inoexecl 1992 Acorelael leyttl Coete. <br /> <br />~ 18&6 Hlfcro-Tr'lId ~\ c.o.u <br /> <br />Figure 2 Indexed Total Cost vs <br />Storage <br /> <br />9 <br /> <br />..- <br /> <br />.. <br />
