<br />. <br /> <br />SECTION V <br />POWER PRODUCTION STUDIES <br /> <br />A. GENERAl <br />The primary objective of the power production studies was to <br />establish the installed capacity and reservoir operation criteria <br />(discussed in Section III) to maximize hydroelectric power <br />production. <br /> <br />The monthly flows were selected from the average rate of water <br />development conditions (Scenario II) developed by Wright Water <br />Engineers (see Appendix B). Three periods of three consecutive years <br />were se 1 ected to represent the average dry-year, average year, and <br />average wet-year enerqy production. <br /> <br />. <br /> <br />B. INPUT DATA <br />1. Monthly Stream Flows <br />The monthly stream flows were determined by averaging the flow <br />for that month for the three-year period selected. The bas i c <br />data were taken from the table entitled, "Flows out of the <br />Reservoir, Scenario II," Appendix 10 of Wright Water Engineers, <br />August 1984 report, Webster Hill Reservoir Analyses of Expected <br />Water Yield (Appendix B). <br /> <br />Three periods were selected for study; a dry-year period from <br />1954 to 1956 inclusive, an average-year period from 1965 to 1967 <br />inclusive, and a wet-year period of 1970 to 1972 inclusive. <br />Average monthly flows for each three-year periOd were used for <br />power computations. <br /> <br />. <br /> <br />Since this is an essentially run-of-river operation, the <br />releases from the active storage of 20,000 ac-ft were assumed to <br />have negligible effect on the average monthly flow. (The <br />release of 1,000 ac-ft/mo is equal to 16.8 cfs, while a typical <br />average monthly flow is about 3,500 cfs.) <br /> <br />3686-a/9 <br /> <br />V-I <br />
