ment of operation and maintenance costs, interest, and retirement of 
the obligation assumed in the contract. Contracts may be entered into 
with water users' organizations pursuant to the provisions of this Act 
without regard to the last sentence of subsection 9(c) of the Reclama,-
tion Project Act of 1939 (53 Stat. 1187). 
(b) The interest rate used for computing interest during construc-
tion and interest on the unpaid balance of the costs of the project allo-
cated to municipal water supply shall be determined by the Secretary 
of the Treasury, as of the beginning of the fiscal year in which con-
struction is conmienced, on the basis of the computed average interest 
rate payable by the Treasury upon its outstanding marketable public 
obligations which are neither due nor callable for redemption for fif-
teen years from date of issue, and by adjusting such interest rate to 
the nearest multiple of one-eighth of 1 per centum if the computed 
average interest rate is not a multiple of one-eighth of 1 per centum.

organization the care, operation, and maintenance of the project works, 
and, if such transfer is made to credit annually against the organiza-
tion's repayment obligation that portion of the year's operation and 
maintenance costs which, if the United States had continued to operate 
the project, would have been allocated to flood control, fish and wildlife, 
and recreation purposes. Prior to assuming care, operation, and main-
tenance of the project works the water users' organization shall obligate 
itself to operate them in accordance with regulations prescribed by the 
Secretary of the Army with respect to flood control, and by the Secre-
tary of the Interior with respect to fish and wildlife and recreation.

organization, its designee or designee.s, shall be conveyed title to such

delivering project water to water users, and shall have a permanent 
right to use that portion of project reservoir capacity which is or may 
be allocated to municipal and industrial water supply purposes by the 
Secretary of the Interior, so long as the space designated for those 
purposes may be physically available, taking into account such equi-
table reallocation of reservoir storage capacities among the purposes 
to be served by the project as may be necessary due to sedimentation, 
subject, if the project is then operated by the United States, to payment 
to the United States of a reasonable annual charge to cover operation 
and maintenance costs and a fair share of administrative costs 
applicable to the project. 
SEC. 4. Expenditures for the Mountain Park project may be made 
without regard to the soil survey and land classification requirements 
of the Interior Department Appropriation Act of 1954 (67 Stat 266).

resources and the enhancement of recreation opportunities in con-
nection with the Mountain Park reclamation project shall be in accord-
ance with the Federal Water Project Recreation Act (79 Stat. 213) p

tion of the Mountain Park Reclamation Project the sum of $19,978,000

justified by reason of ordinary fluctuations in construction costs as 
indicated by engineering cost indexes applicable to the type of con-
