Annual flood control <br />benefits, based upon data supplied by the Corps of Engineers, would <br />be about $11,500. <br />AlLhough the reach of Fryingpan River which would be inundated <br />by the reservoir now supports an important trout fishery, the. net effect <br />of project operation will be beneficial to fish. The stabilized releases <br />from the darn will improve fish habit.at downstream, and the reservoir <br />will provide greater fishing opport.unities than t.he reach of the natural <br />stream involved. The Fish and Wildlife SerTiee estimates an annual <br />project benefit of $172,000 due to enhancement of the fishery. <br />Considerable llse will be made of Ruedi ResenToir for recreation <br />purposes. Provision of minimum basic recreational fac.ilities and of <br />facilit.ies to protect t.he health and safety of the visiting public has <br />been estimated by the National Park Service at about $:j5,OOO. This <br />specific cost. has heen allocated to reel'E'ation. Opportunities will exist <br />for further rle,.elopment. of the recreation potential of Huedi Reser- <br />voir under the administration of the Forest Service. The Hnllual <br />recreation benefits hnve been est.imated at $80,000 by the N ationlLl Park <br />Service. <br />The active capncit.y of Ruedi Reservoir, in excess of thp.. Fryingpan- <br />_\rkansas project. replacement requirements if operated jointly for <br />flood control and conservaHon purposes, could SlIp ply 70,000 acre- <br />feet of usable water in a critical year such as lfJ34. There are poten- <br />tialities for future use of snch conservution capacity for irrigation, <br />but it. is expected that the development nnd growth of the oil shale <br />indnstry will crente a prior market for this water. The value of <br />Ruedi Reservoir water for municipal and industrial use was based <br />upon the cost of the chea.pest alternative single-purpose project and <br />resulted in annual eqnivalent costs of $415,000 and $323,000 on 50- <br />and lOO-year periods of analysis, respectively. <br />Considering only the portion of the cost of Rnedi Dam and Res- <br />ervoir assignable to western slope regu lutor)' storage, since the portion <br />assignable to the FryingpaJlwArkllmms I,Jroject has been found finan- <br />cinlly feasible and economically justified III the analyses of tlrat. project, <br />l'ltt.ios of annual benetits to allnual costs for t'hat part of the develop. <br />ment.areculculated thus: <br /> <br />I ~ <br />I <br /> <br />5O-vear <br />anniys!5 <br /> <br />100-year <br />o.na[ysis <br /> <br />....nnuol blltletl.ts__ _.._._._.__.._ __.._n_____.___.. ___hn__n_. _._ .._____ $6;8,500. _ __~__ $.586.500. <br />Anml3l C05t.~__. __n_n_______ _ ._._ .___.___________._. _______un_____ __ SlO8.0oo. .--.__ $1&1,300. <br />Rallo of benefits to custs_____.. _".u.._u_____".___________._____.".____ 3.:.16 to L.n_n 3.57 to 1. <br />
