This <br />treatment of the cost was adopted in the legislation to avoid allocations <br />of Fryingpan-Arkansas project costs to "deferred uses." It was brought <br />out in congressional hearings, however, that at such time as western slope <br />uses of Ruedi Reservoir storage are proposed for authorization, the legis- <br />lation would provide that the Fryingpan-Arkansas project be relieved of <br />an appropriate share of the reimbursable costs of Ruedi Dam and Reservoir. <br />Thus, the Fryingpan-Arkansas project will serve as an underwriter for <br />repayment of costs of capacity in Ruedi Reservoir in excess 0:1' that <br />required for replacement, but lvill not relieve fUture Colorado River Basin <br />projects of their customary economic and financial responsibilities. <br /> <br />The supplemental report on the Ruedi Dam and Reservoir mentioned <br />above points out that the active reservoir capacity in excess of that for <br />replacement, if operated jointly for flood control and conservation pur- <br />poses, could supply an average of 70,000 acre-feet of water annually for <br />future d01mstream developments. The reports Which follow show that, based <br />on long-term reservoir yield, the average annual releases from Ruedi Res- <br />ervoir required for the Basalt project would be 40,000 acre-feet and for <br />the Bluestone project, 21,000 acre-feet. This would leave 9,000 acre-feet <br />for a possible expansion of the Basalt and Bluestone project plans to <br />include additional lands or for other future uses on the western slope. <br />If western slope costs were prorated among potential developments in pro- <br />portion to requirements for storage lvater, the distribution ,Tould be as <br />follows: <br /> <br />Project <br />Basalt <br />Bluestone <br />Other <br />Total <br /> <br />Construction <br />cost <br />$1,885,000 <br />990,200 <br />425,500 <br />3,300,700 <br /> <br />Interest <br />during <br />construction <br />$151,600 <br />80,000 <br />34,000 <br />265,600 <br /> <br />Annual <br />operation <br />and <br />maintenance <br />$2,100 <br />1,200 <br />400 <br />3,700 <br /> <br />The Basalt and Bluestone projects appear to represent two favorable <br />potentialities for the use of Ruedi Reservoir water. Both are shown by <br />the following reconnaissance reports to have favorable benefit-cost ratios. <br />Their reimbursable costs could be fully repaid within 50-year repayment <br />periods provided the projects are authorized as participating projects <br />with the Colorado River Storage project. Both projects are vTorthy of <br />detailed feasibility studies which will be scheduled as funds and person- <br />nel become available for that purpose. In the detailed studies alterna- <br />tive plans of development will be further considered, particularly <br />possibilities of expanding the Basalt project to include irrigation <br /> <br />3 <br />
