Boulder Canyon Project Act

BOULDER CANYON PROJECT ACT
[PUBL IC -NO . 642-70TH CONGRESS )
[H. R. 5773]
AN ACT To provide for the construction of works for the protection and development of the Colorado
River Basin, for the approval of the Colorado River compact, and for other purposes.
Be it enacted by the Senate and House of Representatives of the United States of America in
Congress assembled, That for the purpose of controlling the floods, improving navigation and regulating
the flow of the Colorado River, providing for storage and for the delivery of the stored waters thereof for
reclamation of public lands and other beneficial uses exclusively within the United States, and for the
generation of electrical energy as a means of making the project herein authorized a self-supporting and
financially solvent undertaking, the Secretary of the Interior, subject to the terms of the Colorado River
compact hereinafter mentioned, is hereby authorized to construct, operate, and maintain a dam and
incidental works in the main stream of the Colorado River at Black Canyon or Boulder Canyon adequate
to create a storage reservoir of a capacity of not less than twenty million acre-feet of water and a main
canal and appurtenant structures located entirely within the United States connecting the Laguna Dam, or
other suitable diversion dam, which the Secretary of the Interior is hereby authorized to construct if
deemed necessary or advisable by him upon engineering or economic considerations, with the Imperial
and Coachella Valleys in California, the expenditures for said main canal and appurtenant structures to be
reimbursable, as provided in the reclamation law, and shall not be paid out of revenues derived from the
sale or disposal of water power or electric energy at the dam authorized to be constructed at said Black
Canyon or Boulder Canyon, or for water for potable purposes outside of the Imperial and Coachella
Valleys: Provided, however, That no charge shall be made for water or for the use, storage, or delivery
of water for irrigation or water for potable purposes in the Imperial or Coachella Valleys; also to
construct and equip, operate, and maintain at or near said dam, or cause to be constructed, a complete
plant and incidental structures suitable for the fullest economic development of electrical energy
from the water discharged from said reservoir; and to acquire by proceedings in eminent domain, or
otherwise all lands, rights-of-way, and other property necessary for said purposes.
SEC. 2. (a) There is hereby established a special fund, to be known as the “Colorado River Dam
fund” (hereinafter referred to as the “fund”), and to be available, as hereafter provided, only for carrying
out the provisions of this Act. All revenues received in carrying out the provisions of this Act shall be
paid into and expenditures shall be made out of the fund, under the direction of the Secretary of the
Interior.
(b)
The Secretary of the Treasury is authorized to advance to the fund, from time to time and
within the appropriations therefor, such amounts as the Secretary of the Interior deems necessary for
carrying out the provisions of this Act, except that the aggregate amount of such advances shall not
exceed the sum of $165,000,000. Of this amount the sum of $25,000,000 shall be allocated to flood
control and shall be repaid to the United States out of 62½ per centum of revenues, if any, in excess of
the amount necessary to meet periodical payments during the period of amortization, as provided in
section 4 of this Act. If said sum of $25,000,000 is not repaid in full during the period of amortization,
then 62½ per centum of all net revenues shall be applied to payment of the remainder. Interest at the rate
of 4 per centum per annum accruing during the year upon the amounts so advanced and remaining unpaid
shall be paid annually out of the fund, except as herein otherwise provided.

(c)
Moneys in the fund advanced under subdivision (b) shall be available only for
expenditures for construction and the payment of interest, during construction, upon the amounts so
advanced. No expenditures out of the fund shall be made for operation and maintenance except from
appropriations therefor.
(d)
The Secretary of the Treasury shall charge the fund as of June 30 in each year with such
amount as may be necessary for the payment of interest on advances made under subdivision (b) at the
rate of 4 per centum per annum accrued during the year upon the amounts so advanced and remaining
unpaid, except that if the fund is insufficient to meet the payment of interest the Secretary of the Treasury
may, in his discretion, defer any part of such payment, and the amount so deferred shall bear interest at
the rate of 4 per centum per annum until paid.
(e)
The Secretary of the Interior shall certify to the Secretary of the Treasury, at the close of
each fiscal year, the amount of money in the fund in excess of the amount necessary for construction,
operation, and maintenance, and payment of interest. Upon receipt of each such certificate the Secretary
of the Treasury is authorized and directed to charge the fund with the amount so certified as repayment of
the advances made under subdivision (b), which amount shall be covered into the Treasury to the credit
of miscellaneous receipts.
SEC. 3. There is hereby authorized to be appropriated from time to time, out of any money in the
Treasury not otherwise appropriated, such sums of money as may be necessary to carry out the purposes
of this Act, not exceeding in the aggregate $165,000,000.
SEC. 4. (a) This Act shall not take effect and no authority shall be exercised hereunder and no
work shall be begun and no moneys expended on or in connection with the works or structures provided
for in this Act, and no water rights shall be claimed or initiated hereunder, and no steps shall be taken by
the United States or by others to initiate or perfect any claims to the use of water pertinent to such works
or structures unless and until (1) the States of Arizona, California, Colorado, Nevada, New Mexico, Utah,
and Wyoming shall have ratified the Colorado River compact, mentioned in section 13 hereof, and the
President by public proclamation shall have so declared, or (2) if said States fail to ratify the said compact
within six months from the date of the passage of this Act then, until six of said States, including the State
of California, shall ratify said compact and shall consent to waive the provisions of the first paragraph of
Article XI of said compact, which makes the same binding and obligatory only when approved by each of
the seven States signatory thereto, and shall have approved said compact without conditions, save that of
such six-State approval, and the President by public proclamation shall have so declared, and, further,
until the State of California, by act of its legislature, shall agree irrevocably and unconditionally with the
United States and for the benefit of the States of Arizona, Colorado, Nevada, New Mexico, Utah, and
Wyoming, as an express covenant and in consideration of the passage of this Act, that the aggregate
annual consumptive use (diversions less returns to the river) of water of and from the Colorado River for
use in the State of California, including all uses under contracts made under the provisions of this Act and
all water necessary for the supply of any rights which may now exist, shall not exceed four million four
hundred thousand acre-feet of the waters apportioned to the lower basin States by paragraph (a) of Article
III of the Colorado River compact, plus not more than one-half of any excess or surplus waters
unapportioned by said compact, such uses always to be subject to the terms of said compact.
The States of Arizona, California, and Nevada are authorized to enter into an agreement which
shall provide (1) that of the 7,500,000 acre-feet annually apportioned to the lower basin by paragraph (a)
of Article III of the Colorado River compact, there shall be apportioned to the State of Nevada 300,000
acre-feet and to the State of Arizona 2,800,000 acre-feet for exclusive beneficial consumptive use in
perpetuity, and (2) that the State of Arizona may annually use one-half of the excess or surplus waters

unapportioned by the Colorado River compact, and (3) that the State of Arizona shall have the exclusive
beneficial consumptive use of the Gila River and its tributaries within the boundaries of said State, and
(4) that the waters of the Gila River and its tributaries, except return flow after the same enters the
Colorado River, shall never be subject to any diminution whatever by any allowance of water which may
be made by treaty or otherwise to the United States of Mexico but if, as provided in paragraph (c) of
Article III of the Colorado River compact, it shall become necessary to supply water to the United States
of Mexico from waters over and above the quantities which are surplus as defined by said compact, then
the State of California shall and will mutually agree with the State of Arizona to supply, out of the main
stream of the Colorado River, one-half of any deficiency which must be supplied to Mexico by the lower
basin, and (5) that the State of California shall and will further mutually agree with the States of Arizona
and Nevada that none of said three States shall withhold water and none shall require the delivery of
water, which cannot reasonably be applied to domestic and agricultural uses, and (6) that all of the
provisions of said tri-State agreement shall be subject in all particulars to the provisions of the Colorado
River compact, and (7) said agreement to take effect upon the ratification of the Colorado River compact
by Arizona, California, and Nevada.
(b)
Before any money is appropriated for the construction of said dam or power plant, or any
construction work done or contracted for, the Secretary of the Interior shall make provision for revenues
by contract, in accordance with the provisions of this Act, adequate in his judgment to insure payment of
all expenses of operation and maintenance of said works incurred by the United States and the repayment,
within fifty years from the date of the completion of said works, of all amounts advanced to the fund
under subdivision (b) of section 2 for such works, together with interest thereon made reimbursable under
this Act.
Before any money is appropriated for the construction of said main canal and appurtenant
structures to connect the Laguna Dam with the Imperial and Coachella Valleys in California, or any
construction work is done upon said canal or contracted for, the Secretary of the Interior shall make
provision for revenues, by contract or otherwise, adequate in his judgment to insure payment of all
expenses of construction, operation, and maintenance of said main canal and appurtenant structures in the
manner provided in the reclamation law.
If during the period of amortization the Secretary of the Interior shall receive revenues in excess
of the amount necessary to meet the periodical payments to the United States as provided in the contract,
or contracts, executed under this Act, then, immediately after the settlement of such periodical payments,
he shall pay to the State of Arizona 18¾ per centum of such excess revenues and to the State of Nevada
18¾ per centum of such excess revenues.
SEC. 5. That the Secretary of the Interior is hereby authorized, under such general regulations as
he may prescribe, to contract for the storage of water in said reservoir and for the delivery thereof at such
points on the river and on said canal as may be agreed upon, for irrigation and domestic uses, and
generation of electrical energy and delivery at the switchboard to States, municipal corporations, political
subdivisions, and private corporations of electrical energy generated at said dam, upon charges that will
provide revenue which, in addition to other revenue accruing under the reclamation law and under this
Act, will in his judgment cover all expenses of operation and maintenance incurred by the United States
on account of works constructed under this Act and the payments to the United States under subdivision
(b) of section 4. Contracts respecting water for irrigation and domestic uses shall be for permanent
service and shall conform to paragraph (a) of section 4 of this Act. No person shall have or be entitled to
have the use for any purpose of the water stored as aforesaid except by contract made as herein stated.
After the repayments to the United States of all money advanced with interest, charges shall be
on such basis and the revenues derived therefrom shall be kept in a separate fund to be expended within
the Colorado River Basin as may hereafter be prescribed by the Congress.

General and uniform regulations shall be prescribed by the said Secretary for the awarding of
contracts for the sale and delivery of electrical energy, and for renewals under subdivision (b) of this
section, and in making such contracts the following shall govern:
(a)
No contract for electrical energy or for generation of electrical energy shall be of longer
duration than fifty years from the date at which such energy is ready for delivery.
Contracts made pursuant to subdivision (a) of this section shall be made with a view to obtaining
reasonable returns and shall contain provisions whereby at the end of fifteen years from-the date of their
execution and every ten years thereafter, there shall be readjustment of the contract, upon the demand of
either party thereto, either upward or downward as to price, as the Secretary of the Interior may find to be
justified by competitive conditions at distributing points or competitive centers and with provisions under
which disputes or disagreements as to interpretation or performance of such contract shall be determined
either by arbitration or court proceedings, the Secretary of the Interior being authorized to act for the
United States in such readjustments or proceedings.
(b)
The holder of any contract for electrical energy not in default thereunder shall be entitled
to a renewal thereof upon such terms and conditions as may be authorized or required under the then
existing laws and regulations, unless the property of such holder dependent for its usefulness on a
continuation of the contract be purchased or acquired and such holder be compensated for damages to its
property, used and useful in the transmission and distribution of such electrical energy and not taken,
resulting from the termination of the supply.
(c)
Contracts for the use of water and necessary privileges for the generation and distribution
of hydroelectric energy or for the sale and delivery of electrical energy shall be made with responsible
applicants therefor who will pay the price fixed by the said Secretary with a view to meeting the revenue
requirements herein provided for. In case of conflicting applications, if any, such conflicts shall be
resolved by the said Secretary, after hearing, with due regard to the public interest, and in conformity
with the policy expressed in the Federal Water Power Act as to conflicting applications for permits and
licenses, except that preference to applicants for the use of water and appurtenant works and privileges
necessary for the generation and distribution of hydroelectric energy, or for delivery at the switchboard of
a hydroelectric plant, shall be given, first, to a State for the generation or purchase of electric energy for
use in the State, and the States of Arizona, California, and Nevada shall be given equal opportunity as
such applicants.
The rights covered by such preference shall be contracted for by such State within six months
after notice by the Secretary of the Interior and to be paid for on the same terms and conditions as may be
provided in other similar contracts made by said Secretary: Provided, however, That no application of a
State or a political subdivision for an allocation of water for power purposes or of electrical energy shall
be denied or another application in conflict therewith be granted on the ground that the bond issue of such
State or political subdivision, necessary to enable the applicant to utilize such water and appurtenant
works and privileges necessary for the generation and distribution of hydroelectric energy or the
electrical energy applied for, has not been authorized or marketed, until after a reasonable time, to be
determined by the said Secretary, has been given to such applicant to have such bond issue authorized
and marketed.
(d)
Any agency receiving a contract for electrical energy equivalent to one hundred thousand
firm horsepower, or more, may, when deemed feasible by the said Secretary, from engineering and
economic considerations and under general regulations prescribed by him, be required to permit any other
agency having contracts hereunder for less than the equivalent of twenty-five thousand firm horsepower,

upon application to the Secretary of the Interior made within sixty days from the execution of the contract
of the agency the use of whose transmission line is applied for, to participate in the benefits and use of
any main transmission line constructed or to be constructed by the former for carrying such energy (not
exceeding, however, one-fourth the capacity of such line), upon payment by such other agencies of a
reasonable share of the cost of construction, operation, and maintenance thereof.
The use is hereby authorized of such public and reserved lands of the United States as may be
necessary or convenient for the construction, operation, and maintenance of main transmission lines to
transmit said electrical energy.
SEC. 6. That the dam and reservoir provided for by section 1 hereof shall be used: First, for river
regulation, improvement of navigation, and flood control; second, for irrigation and domestic uses and
satisfaction of present perfected rights in pursuance of Article VIII of said Colorado River compact; and
third, for power. The title to said dam, reservoir, plant, and incidental works shall forever remain in the
United States, and the United States shall, until otherwise provided by Congress, control, manage, and
operate the same, except as herein otherwise provided: Provided, however, That the Secretary of the
Interior may, in his discretion, enter into contracts of lease of a unit or units of any Government-built
plant, with right to generate electrical energy, or, alternatively, to enter into contracts of lease for the use
of water for the generation of electrical energy as herein provided, in either of which events the
provisions of section 5 of this Act relating to revenue, term, renewals, determination of conflicting
applications, and joint use of transmission lines under contracts for the sale of electrical energy, shall
apply.
The Secretary of the Interior shall prescribe and enforce rules and regulations conforming with
the requirements of the Federal Water Power Act, so far as applicable respecting maintenance of works in
condition of repair adequate for their efficient operation, maintenance of a system of accounting, control
of rates and service in the absence of State regulation or interstate agreement valuation for rate-making
purposes, transfers of contracts, contracts extending beyond the lease period, expropriation of excessive
profits, recapture and/or emergency use by the United States of property of lessees, and penalties for
enforcing regulations made under this Act of penalizing failure to comply with such regulations or with
the provisions of this Act. He shall also conform with other provisions of the Federal Water Power Act
and of the rules and regulations of the Federal Power Commission, which have been devised or which
may be hereafter devised, for the protection of the investor and consumer.
The Federal Power Commission is hereby directed not to issue or approve any permits or licenses
under said Federal Water Power Act upon or affecting the Colorado River or any of its tributaries, except
the Gila River, in the States of Colorado, Wyoming, Utah, New Mexico, Nevada, Arizona, and California
until this Act shall become effective as provided in section 4 herein.
