<br />I 1099 <br />I <br />I <br />I <br />I. <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br /> <br />depletions set forth in the Missouri River Basin Framework <br /> <br />Plan except portions of the private irrigation developments <br /> <br />not supported by storage facilities. Estimated associated <br /> <br />depletion reduction from the Framework Plan for the private <br /> <br />irrigation deleted is about l.8 million acre-feet. <br /> <br />The current depletions outlook recognizes a slower rate of <br /> <br />irrigation development than estimated in 1963. Large projects <br /> <br />authorized in the past few years have been slowed or temporar- <br /> <br />ily stopped due to budget limitations. <br /> <br />Comparing the present depletion study with the 1963 depletion <br /> <br />allowance, there now is less water depleted and more water <br /> <br />available for generation until the year 2020.(Exhibit A-I). <br /> <br />In the Western Division, the adverse year dependable <br /> <br />capacity which .can be supported by the energy produced <br /> <br />in an average water year was determined by an energy <br /> <br />capability study resulting from a series of operational <br /> <br />studies in 1956 which became the basis for the allocations <br /> <br />of power from Western Division, P-S MBP in 1962. This <br /> <br />energy capability study was based on assumed system inflow <br /> <br />conditions derived from available runoff data for the <br /> <br />48-year period from 1906 to 1954. One-half the estimated <br /> <br />average annual firm output of Yellowtail Powerplant was <br /> <br />added to the average annual energy from the study to <br /> <br />l7 <br />
