Question: Due to the fact that Bijou Creek waters contain much sediment, it is important to know how these waters will be handled. Arlswer: See answer 1 above. SECTION FIVE 1~~OELECTaIC POWER 1. Question: Among the purposes for which the Narrows Dam is to be constructed is the possible production of hydroelectric power. What studies and what informetion is now evailable concerning tIlis phase of the construction? Answer: The Kegional Counsel has rendered an opinion that con- struction-or-a-hydroelectric pawerplant at Narrows is not at prese~t authorized and that, if such construction is to be ,~.dertaken, further ConEressional action will be required as it constitutes a change in pur- pose,from that outlined in Senate uocument 191, 78th Congress, 2nd Session. However, the possibilities of such construction are being ex- plored and cost estimates are being made for two differently sized plants. The only structural difference in the design of the d~~ ar-d appurtenant wor~<s which would be required for installation of a pOVfer- plant would be the arrangen~nt of the river outlet to insure that t~6 design would be adaptable to the inclusion of a pcrwer~lant at seme future time. It wO'lld be very short-sighted on the pal't of tree Govern- m.ent not tv insure such provision if it cun be made at no great increase in cost. 2. electric Question: Does the J)ur2au anticipate that reasonably priced power c.ould be prod1..:.ced ill such a project as the one pro?osed? Answer: In any analysis of a proposed hydroelectric develop- ment, construction costs wtich must be allocated to power are first determined. This construction cost is th8n reduced to an annual paymeDt which must be made to retire the construction cost allocated to power, plus interest OD the unpnid balance at three percent in ~ 50-year period. To this annual construction charge must be added an allowance for re- placement sufficient in amount to maintain the plant in top operating condition. T;~e estimated annnal ccst of operation a.nd rr,aintenance is also added. The StlID of these factors is then the total annual charge which the pawerplant must te capable of paying. The amount of energy which the plant is capable of generating is computed and segregated into classes of power such ns firm, secondary, or fuel replacement. The amount of energy which can b" produced, properly weighted according: to cl~ss, is then compared to the total annual charge which the plant must earn to determine the rates at which electricity must be sold in order to return the annual charge. If the rates thus determined nre not con- sidered competitive within the power market area, the plant, of course, 12
