<br />onl~3~ <br /> <br />. <br /> <br />. <br /> <br />However, in order te regulate the irrigation wator after it has reached the <br />Fountain Valloy, the constru.ctien of a new reservoi!' or tho enlo.rgenent of <br />sone existing reservoir would be necossary. Sinilarly# the conclusion that <br />power could be purchasod choaper than it could bo gonoratod with the punped <br />water is roaffirnod. all water divorted fron tho South Platte Rivor undor <br />this plan would roquire replaCel:lent. That could be acconplished with trans. <br />mountain water upon construotion of the potential Blue-South Platto projoct. <br /> <br />23. This plan, as undor the single-purpose plan. would roquire oithor: <br />(a) the construction of a regu.lating roservoir on the South Platte River. <br />or (b) agreemont with tho City and County of Denver for use of tho antoro <br />and Elevon Milo Cc.nyon Reservoirs.. Tho OJq,.onses involved in oithor roquire_ <br />nent are not incluced in the subsequent fiscal amlysis. <br /> <br />24. Beeause of the dual function of nost facilities__for su.pplying <br />nunicipal and irrigation wc.tor--costs would be allocated to each function <br />thereby roducing tho costs fron those rcquired for corrospo!\ding singlo- <br />purposo facilities. Thus, the cost of 5,000 acro-foot of nunicipal wator <br />under tho dual-purpose plan would be about $45.54 par acre-foot, in con- <br />trast with $95.83 par acre-foot far tho sat~ m:tount of water undor tho <br />singlo_purpose plan. Bath cost oalculations utilize anortizatiol1s of allo- <br />cated construction casts over 40 years with interest at 2-1/2 percent. <br />annuc.l O&:M, and the basic cost of $20 par acre..,foot for :nunioipnl wator at <br />tho sourco of supply. <br /> <br />25. Construction costs allocatod to irriGation undor tho dual-purpose <br />plan~ould bo roinbursod ;-- ~R J ,. without intorest. The totnl annunl <br />cost of tho puriped irrigntion wator would be ~38.64 pOl' c.crs-foot. which <br />consists of nn nnortization of the allocatod construction cost without <br />intorest, allocated O&:t~ and tho busic cost of w20 pOl' acro-foot for water <br />at tho sourco of supply, <br /> <br />26. Tho 40,000 acro-foet of irrigation wator would furnish a full <br />supply for 12,000 acrcs of non~irrigatod land in tho Fountain Valloy. <br />Roturn flows fron that water and fron nunicipal wc.tor would provido a <br />supplonontal irrigation supply fOr sone 15,000 :lorOS of prosontly irriga_ <br />tod land lower in tho Fountain Valloy. Tho payment capacity of the <br />irrigable lands with tho now supply is estinntod at ~5.00 pOl' acro c.nnunlly. <br />Operation, naintonanoo, nnd roplaoonont oxponsos on tho storago and dis_ <br />tribution systons alono would anount to about :~2.25 pOl' aorc. Tho ronain- <br />ing $2.75 pOl' acre would bo insufficient to ~ot the other allocatod oosts <br />Which would include tho following~ an11uo.l O',l\i. &: R. for punping, including <br />pmvor costs, construction costs of the pumping systen, and constructicn <br />cost of tho irrigation rogulc.tory roservoir. To Sl.m:',lUrizol tho total <br />D.l;Ulual cost of the pur.1pod we. tel' wo\l1d bo ~38. 64 pOl' acro-foot, tho total <br />paynont capncity of tho irrigatod lands would bQ about ~5.00 pOl' acro. <br /> <br />7 <br /> <br />
