<br />What is a ki/mvatt-hour?
<br />It is a unit of work or energy equal to
<br />that done by one kilowatt of power act-
<br />ing for one hour. A kilowatt is 1,000
<br />watts or 1.34 horscpower.
<br />
<br />Who opaafe.r and maiwains rhe
<br />pO'fi'el7J/anf ?
<br />The pov,.'clvlant is operated and main-
<br />tained directly by the Bureau of Re-
<br />clamation except for the generating
<br />machinery. which is operated and main~
<br />tained directly through the City of Los
<br />Angeles Department of Water and Power
<br />and the Southern California Edison Co.,
<br />the operating agents. The City of Los
<br />Angeles generates for itscl f, other
<br />municipal itics. the States of Arizona and
<br />Nevada, and the Metropolitan Water
<br />District of Southern Calitomia. Southern
<br />California Edison generates for itself.
<br />
<br />U110 are the principal coJ//ractors for
<br />enerKV?
<br />The States of Arizona and Nevada, the
<br />City of Los Angeles Department of
<br />Water and Power, the Southern Califor-
<br />nia Edison Co., the Metropolitan Water
<br />District of Southern Califomia, and the
<br />cities of Glendale, Burbank, and
<br />Pasadena.
<br />
<br />How is rhe }inn energy generated at
<br />Hoover Dam allocated?
<br />States of Arizona and Nevada, 17.6259
<br />percent each; Mctropolitan Watcr District
<br />of Southern Calil()rnia, 35.2517 percent;
<br />city of Burbank, 0.5773 percent; city of
<br />Glendale, 1.8475 percent; city of
<br />Pasadena, 1.5847 percent; city of Los
<br />Angeles, 17.5554 percent; Southern
<br />California Edison Co., 7.9316 pcrcent.
<br />
<br />How is the inconIe from the sale of
<br />energy used?
<br />To pay all operation and maintenance
<br />expenses and to repay the major part of
<br />the construction cost of the dalll and
<br />powerplant, at interest not exceeding 3
<br />
<br />48
<br />
<br />percent. The cost of construction com-
<br />pleted and in service by 1937 will be
<br />rcpaid by May 3 I, 1987. All othcr costs
<br />will bc repaid within 50 years of the date
<br />of installation or as established by Con-
<br />gress. Repayment of the $25 million con-
<br />struction cost allocated to flood control is
<br />deferred beyond 1987, when further ac-
<br />tion will be subject to Congrcssional
<br />direction. Arizona and Nevada each
<br />rceeive $300,000 annuafly, paid from
<br />revenues, and $500,000 annually is set
<br />aside from revenues for further irrigation
<br />and power development of the Colorado
<br />River Basin.

<br />Colorado River Water Allocation
<br />
<br />What Stares have beneficial interests in
<br />the Colorado River system?
<br />Those lying within the Colorado River
<br />Basin: Arizona, California, Colorado,
<br />Nevada, New Mexico, Utah, and
<br />Wyoming. Each of these States is party
<br />to the Colorado River Compact entered
<br />into in Santa Fe, New Mexico, on
<br />November 24, 1922. The compact has
<br />becn ratified by the legislatures of all the
<br />signatory States.
<br />
<br />How is the Colorado River Basin
<br />divided?
<br />The Colorado River Compact divided the
<br />Colorado River Basin into the Upper
<br />Basin and the Lower Basin. The division
<br />point is Lees Ferry, a point in the
<br />Tllainstem of the Colorado River about
<br />30 river miles south of the Utah~Arizona
<br />boundary. The "Upper Basin" includes
<br />those parts of the States of Arizona, Col-
<br />orado, New Mexico, Utah, and Wyom-
<br />ing within and from which waters
<br />naturally drain into the Colorado River
<br />system above Lees Ferry, and all parts of
<br />these States that are not paJ1 of the
<br />river's drainage system but may benefit
<br />from water diverted from the system
<br />above Lees Ferry.
<br />The "Lower Basin" includes those
<br />PaIlS of the States of Arizona, Califor-
<br />nia, Nevada, New Mexico, and Utah
<br />within and from which waters naturally
<br />drain into the Colorado River system
<br />below Lees Ferry, and all parts of these
<br />
<br />States that are not part of the river's
<br />drainage system but may benefit from
<br />water diverted from the system below
<br />Lees Ferry.
<br />
<br />How is Colorado River water
<br />apportioned?
<br />The Colorado River Compact appor-
<br />tioned to each basin the exclusive,
<br />beneficial consumptive use of 7,500,000
<br />acre-feet of water per year from the Col-
<br />orado Rivcr system in perpetuity. In ad-
<br />dition, the compact gave to the Lower
<br />Basin the right to increase its annual
<br />beneficial consumptive use of such water
<br />by 1,000,000 acre-feet.
<br />
<br />How much ~varer is each State in the
<br />Colorado River Basin apPol1ioned?
<br />The Colorado River Compact did not ap-
<br />portion water to any State.
<br />On October II, 1948, the Upper Basin
<br />States entered into the Upper Colorado
<br />River Basin Compact, which apportioned
<br />use of the Upper Basin waters among
<br />them. The compact permits Arizona to
<br />use 50,000 acre-feet of water annually
<br />from the upper Colorado River system,
<br />and apportioned the remaining water to
<br />the Uppcr Basin States in the following
<br />percentagcs: Colorado, 51.75 percent;
<br />New Mexico, 11.25 percent; Utah, 23
<br />percent; and Wyoming, 14 percent.
<br />The Lower Basin States of Arizona,
<br />California, and Nevada were not able to
<br />reach agreement. In 1952, Arizona filed
<br />suit in the United States Supreme Court
<br />to determine how the waters of the
<br />Lower Basin should be divided. In Oc-
<br />tober 1962, the Court ruled that of the
<br />first 7,500,000 acre-feet of mainstem
<br />water in the Lower Basin, California is
<br />entitled to 4,400,000 acre-feet, Arizona
<br />2,800,000 acre-feet, and Nevada, 300,000
<br />acre-feet.
<br />The United States has contracted with
<br />the States of Arizona and Nevada and
<br />with various agencies in Arizona and
<br />California for the delivery of Colorado
<br />River water. These contracts make
<br />delivery of the water contingent upon its
