<br />these circlUnstances, it, probably will be more practical to ant.icipate
<br />a future repayment eontraet based upon amortizat.ion of allocated .
<br />costs by equal annual payments rather than by wat.er serVIce c.ha.rges
<br />OIl an acre-foot basis. For purposes of illustratIOn, however, the
<br />required annual charge of $130,000 for municipal and industrial
<br />water as related to the average annual water reqUIrements of J4,GOO
<br />acre-feet, as retleeted by hydrologic studies, would amount to about
<br />$3.75 an acre-foot.
<br />During tlH~ deferred 01' accrual-use period, or prior to t.he execution
<br />of a repayment contract, it is proposed that the operation, mainte-
<br />nanee, and replaeement of $2,300 annunlly which has been assigned to
<br />munieipal and industrial water would be prorated among the remain-
<br />ing w".,tern-slope funetions of flood control, fish and wildlife, and
<br />recreation.
<br />
<br />CONCLUSIONS AND RECOMMENDATIONS
<br />
<br />Condu~~ion8
<br />Based upon reconnaissance or preliminary data, construction of the
<br />Ruedi Dam .nd Reservoir appears to he feasible. More detailed in-
<br />vestigations will be required to prepare final designs and est.imates for
<br />eonstruction of t.he dam and reservoir.
<br />After making releases of \vater :from Ruedi Reservoir to meet down-
<br />stream vest.ed rights nnd replu.eeme.nt requirement.s stemming from
<br />di\"ersions by t.he Fryingpan-Arkansas project. and making bypasses
<br />for fish in the Fryingpan River, the reservoir would pro\"ide ,0,000
<br />acre-feet of storage water which, together with n.vnilnbJe stre,amflows,
<br />will meet future requirements for municipal and industrinl water
<br />expeeted to arise from commereial oil shale development in western
<br />Colol"lldo.
<br />In addition to serving these needs, Ruedi Dam and Reservoir would
<br />provide substantial benefits to fish and wildlife ond reerention. Oper-
<br />ation of the reservoir also would result in some benefits to flood control
<br />through storage of snowmelt durinp: the potential flood season.
<br />Annual benefits of municipal and industrial water, flood eontrol,
<br />fish and wildlife, and recreation provide eeonomic justifieat.ion for
<br />those portions of cnpit.al and annual eosts of Ruedi Dam and Reservoir
<br />which are in excess of those borne by the Frying-pan-Arkansas project.
<br />Construction of Rnedi Dam and ReserVOIr as a substitute for Aspen
<br />Dam and Resel"\'oir will not. affed the water supply, justifieation and
<br />feasibility, or plan of de,elopment for other features ofthe Fryingpan-
<br />. >\rkansas project.
<br />Of t.he total estimated projeet eust of $12,83],000 for the Ruedi Dam
<br />and Reservoir, $7,600,000 would be borne by the Frying-pan-Arkansas
<br />project, leaving $5,231,000 .ssoeiated with western Colorado uses of
<br />reservoir water. This amount is tentatively allocated os follows:
<br />FloodlfontroI, $117,500; fish and wildlife, $1,757,800; and recreation,
<br />$55,OOOf-all nonreimbursable--and municipal and industrial water
<br />supply ,'$3,300, 700-rei mbu rsa ble.
<br />In view of deferred use of municipal and industrial water, the allo-
<br />cated project eosts plus an apJ{ropnate share of interest during eon-
<br />struetiQn would be repayable ~ith 'interest in aceordanee with provi-
<br />~ions of the Water Supply Ad of 1958 (Public Law 85-500).
