<br />.', <br /> <br />) <br /> <br />J:"'i <br />: ~ ~.' . <br />, ,. <br /> <br />STATEMENT BY PAUL A. RECHARD <br />TO ILLUSTRATE POINTS 1, 2 AND 3 OF PAGES 11 AND 12 <br />OF CHIEF ENGINEER & SECRETARY'S REPORT <br />July 20, 1960 <br /> <br />The .'.qeneral principles", promulgated by the Secretary of the Interior, <br />set forth as a basic premise that the Upper Basin must make whole Hoover <br />power contracts, at least to the extent that they would have been whole had <br />~len Canyonj and other Upper Basin Storage Units not been on the River. <br />he principles then go on to establish a method for computing the so-called <br />defiCiency in Hoover energy and some general criteria to guide the operation <br />of the reservoirs. The studies made by the Commission staff were for the <br />purpose of analYZing the criteria and did not attempt to consider the basic <br />premise. That is, our studies assumed that Hoover firm contracts would be <br />made whole, even though we did not agree with that premise. <br /> <br />Our first task was to assume detailed operating criteria that would fit <br />within the general criteria. We recognize that the details we picked are <br />probably different from those that another engineer might pick and from the <br />way the Department would operate. However, they are reasonable and <br />since they were used in all of our studies, the results of our studies are <br />comparable. with each other. <br /> <br />Briefly, the details were - - Fill the minimum power pool in Lake <br />Powell as soon as possible without drawing Lake Mead below Hoover <br />power plant rated head and with a minimum release from Glen Canyon of <br />one maf per year. After Glen Canyon power plant is capable of generating, <br />storage in Lake Powell is accumulated up to Glen Canyon power plant rated <br />head as rapidly as possible without drawing Lake Mead below Hoover's <br />rated head. After both reservoirs are at rated head elevation, storable <br />inflow is divided equally until a buffer zone of about three maf of storage <br />is accumulated in both reservoirs. Whenever both reservoirs are at or <br />above this buffer we attempted to generate a predetermined system firm <br />energy of 9 billion kwh per year, without regard to how much was generated <br />at anyone plant. <br /> <br />~I <br />.' <br /> <br />Also, our studies all assumed Lake Mead to be at 25.4 maf total <br />storage (22.0 maf active surface) at the time of closure and a sequence <br />of years following closure similar to the 1930 - 1955 period. <br /> <br />In none of our studies did we completely fill Lake Powell. We <br />terminated the studies in 1987 as set forth in the Secretary's "general <br />principles" . <br /> <br />-15- <br />
