<br />these circumstances, it probably will be more practical to anticipate
<br />a future repayment contract based upon amort.1ZatlOn of allocated
<br />costs by equal annual payments rather than by "ateI' service charges
<br />on an acre-root basis. For purposes of illustratioll, however, the
<br />required annual char"e of $130,000 for municipal and industrial
<br />water as related to t.h~ average annual water requirelnents of 34,GOO
<br />acre-feet, us reflected by hydrologic studies, would amount to about
<br />$3.75 an acre-foot.
<br />During t.he deferred or accru111-use period, or prior to the execution
<br />of a repayment. contract, it is proposed that the. operation, mainte-
<br />nance, a.nd replacement of $2,300 annually which has been assigned to
<br />municipal and indust.rial water would ue prorated among the remain-
<br />ing western-slope functions of flood control, fish and wildlife, and
<br />recreation.

<br />C01/..Clusio'ns
<br />Based upon reconnaissance or preliminary data, construction of the
<br />Ruedi Dnm and Reservoir appears to be feasible. More detailed in-
<br />vestigations will be required to prepare final designs and estimates for
<br />construction of the dam and reservoir.
<br />After making releases of water from Ruedi Reservoir to meet down-
<br />st.ream vested rights find replacement requirements stemming frOln
<br />diversions by the Fryingpnn-Arknl1sas project and making bypnsses
<br />for fish in the Fryingpan River, the reservoir would I,rovlde 70,000
<br />nere-feet of storage water which, together with availab e streamflows,
<br />will meet future requirements for municipal and industrial water
<br />expected to urise from commercial oil shale development in western
<br />Colorndo.
<br />In addit.ion to serving these needs, Ruedi Dl1IIl a.nd Rese,rvoir would
<br />provide substantial benefits to fish and wildlife and recreation. Oper-
<br />ation of the reservoir also would result in some benefits to flood control
<br />through storage of snowmelt dnring the potential flood seaSon.
<br />Annual benefits of municipal and industrial water, flood control,
<br />fish and "ildlife, and recreatil>n provide economic justification for
<br />those portions of capital Rnd annu!ll costs of Ruedi Dam !lnd Resenoir
<br />"hich are in excess of those borne by the Fr)'ingpan-Arkansas project.
<br />Const.ruction of Ruedi Dam and ResenOlr as a substi tute for Aspen
<br />Dam and Reservoir will not affe,ct the water supply, justification and
<br />feasibility, or plan of development for other features of t.he Fryingpan-
<br />Arkansas project.
<br />Of t.he total estimated project cost of $12,831,000 for the Ruedi Dam
<br />arid Reservoir, $7,600,000 would be borne by the Frying"pan-Arkansas
<br />project, leaving $5,231,000 associated "ith western Colorado uses of
<br />resen'oir "ateI'. This amount is tentatively allocated as follo"s:
<br />Flood control, $117,500; fish and wildlife, $1,757,800; and recreation,
<br />$55,000-all nonreimbursable-and municipal and industrial water
<br />supply, $3,300,700-reimbllrsable.
<br />In view of deferred use of municipal and industrial w!lter. the allo-
<br />cated project costs plus an aPP,:"opI:,ate sha~e of interest during con-
<br />structIOn would be repayable With mterest III accordance with provi-
<br />sions of the Water Supply Act of 1958 (Public Law 85-500).
