<br />section of the All-American Canal, this proportion and the method and terms of repayment to be determined by the two
<br />Governments, which, for this purpose, shall take into consideration the proportionate uses of these facilities by the two
<br />countries, these determinations to be made as soon as Davis dam and reservoir are placed in operation.
<br />(b) Annually, a proportionate part ofthe total costs of maintenance and operation ofsuch facilities, these costs to be
<br />prorated between the two countries in proportion to the amount of water delivered annually through such facilities for use
<br />in each ofthe two countries.
<br />
<br />In the event that revenues from the sale of hydro-electric power which may be generated at Pilot Knob become available
<br />for the amortization of part or all ofthe costs ofthe facilities named in subparagraph (a) of this Article, the part that
<br />Mexico should pay of the costs of said facilities shall be reduced or repaid in the same proportion as the balance of the total
<br />costs are reduced or repaid. It is understood that any such revenue shall not become available until the cost of any works
<br />which may be constructed for the generation of hydro-electric power at said location has been fully amortized from the
<br />revenues derived therefrom.
