<br />Due to the increase in Basin storage pro-
<br />vided by the Colorado River Storage Project
<br />reservoirs, releases of water from Hoover
<br />Power plant during recent years have
<br />equaled downstream requirements, Hoover
<br />releases during the year ending May 31,1971,
<br />were 8,144,000 acre-feet.
<br />Total energy delivered to the Hoover pow-
<br />er allottees during operating year 1970-71
<br />was 3,652 million kilowatt hours, Of this
<br />quantity, Hoover generation plus Parker-Da-
<br />vis Interchange amounted to 3,109 million
<br />kilowatt hours, and replacement energy, re-
<br />quired because of energy lost due to the ini-
<br />tial filling of Colorado River Storage Project
<br />reservoirs, amounted to 543 million kilowatt
<br />hours, The largest user of Hoover power was
<br />The Metropolitan Water District of South-
<br />ern California, which took approximately
<br />one-third of the energy delivered to the allot-
<br />tees. Metropolitan is limited in its use of such
<br />energy to the pumping of water into and in
<br />the Colorado River Aqueduct.
<br />Releases from Hoover Dam and delivery of
<br />energy to Hoover Power allottees during the
<br />past nine years are shown in Table 7.

<br />The annual Hoover Power Integration
<br />meeting was held on June 18, 1971, to discuss
<br />water releases and generation for the ensuing
<br />year, The Bureau of Reclamation estimated
<br />the 1971-72 Hoover release at 8,065,000 acre-
<br />feet. Estimated energy delivery, for the same
<br />period ending May 31, 1972, to the Hoover
<br />power allot tees was 3,675 million kilowatt-
<br />hours, or about 91.1 percent of defined firm
<br />energy.
<br />
<br />The 1962 Glen Canyon Filling Criteria, as
<br />modified in 1964, has been described in previ-
<br />ous annual reports of the Board. The Filling
<br />Criteria provides that the United States will
<br />compensate Hoover power allottees for any
<br />deficiency in firm energy generation at Hoo-
<br />ver Powerplant caused by the initial filling of
<br />Lake Powell and other Colorado River Stor-
<br />age Project (CRSP) reservoirs. In the past,
<br />this compensation has been in the form of
<br />energy or money required by the allottees to
<br />replace that eJllergy, including 200 million
<br />kilowatt hours of "impairment" energy re-
<br />sulting from the drawdown of Lake Mead
<br />below elevation 1,123 (rated power head) in
<br />1964 and 1965.
<br />Section 502 of the Colorado River Basin
<br />Project Act of 1968 (PL 90-537), provides
<br />that, beginning in fiscal year 1970, $500,000
<br />per year shall be transferred from the Colo-
<br />rado River Development Fund (established
<br />by the Boulder Canyon Project Adjustment
<br />Act) to the Upper Colorado River Basin
<br />Fund as reimbursement for payments to
<br />Hoover power allottees under the Filling
<br />Criteria (but excluding payments for "im-
<br />pairment" energy), To the extent that any
<br />deficiency in such reimbursement remains as
<br />of June I, 1987, the amount of deficiency shall
<br />be transferred from the Lower ColoradoRiv-
<br />er Basin Development fund (established by
<br />PL 90-537) to the Upper Colorado River Ba-
<br />sin Fund, In reaffirming the Filling Criteria
<br />in ! 970. the Secretary of the Interior stated
<br />that, with minor exceptions, all energy to
<br />meet Hoover power deficiencies would
<br />henceforth be purchased,
<br />On February 27, 1971, the Upper Colorado
<br />River Commission passed a resolution re-
<br />questing the Secretary of the Interior to re-
<br />verse his 1970 decision to continue the Filling
<br />Criteria. Such a reversal would have had the
<br />effect of reimbursing the Upper Colorado
<br />River Basin Fund for the 200 million kilo-
<br />watt hours of impairment energy. The Secre-
<br />tary did not change his d~cision, and the Fill-
<br />ing Criteria is still in effect.
