[76 STAT.
ner: The prospective runoff shall be apportioned between the contractors diverting above and those diverting at or below Navajo Reservoir in the proportion that the total normal diversion requirement of each group bears to the total of all normal diversion requirements. I n the case of contractors diverting above Navajo Reservoir, each such contract shall provide for a sharing of the runoff apportioned to said group in the same proportion as the normal diversion requirement under said contract bears to the total normal diversion requirements of all such contracts that have been made hereunder: Provided, That for any year in which the foregoing sharing procedure either would apportion to any contractor diverting above Navajo Reservoir an amount in excess of the runoff anticipated to be physically available at the point of his diversion, or would result in no water being available to one or more such contractors, the runoff apportioned to said group shall be reapportioned, as near as may be, among the contractors diverting above Navajo Reservoir in the proportion that the normal diversion requirements of each bears to the total normal diversion requirements of the group. In the case of contractors diverting from or below Navajo Reservoir, each such contract shall provide for a sharing of the remaining runoff together with the available storage in the same proportion as then normal diversion requirement under said contract bears to the total normal diversion requirements under all such contracts that have been made hereunder. The Secretary shall not enter into contracts for a total amount of water beyond that which, in his judgment, in the event of shortage, will result in a reasonable amount being available for the diversion requirements for the Navajo Indian irrigation project and the initial stage of the San Juan-Chama project as specified in sections 2 and 8 of this Act. No long-term contract, except contracts for the benefit of the lands and for the purposes specified in sections 2 and 8 of this Act, shall be entered into for the delivery of water stored in Navajo Reservoir or of any other waters of the San Juan River and its tributaries, as aforesaid, until the Secretary has determined by hydrologic investigations that sufficient water to fulfill said contract is reasonably likely to be available for use in the State of New Mexico during the term thereof under the allocations made in articles III and X IV of the Upper Colorado River Basin compact, and has submitted such determination to the Congress of the United States and the Congress has approved such contracts: Provided, That nothing contained in the foregoing shall be construed to forbid the Secretary from entering into temporary water supply contracts in the San Juan River Ba^in for any year in which he determines that water legally available for use in the upper basin of the Colorado River system would otherwise not be used there and is not needed to fulfill the obligations of the upper division States with respect to delivery of water at Lee Ferry. (b) If contracts are entered into for delivery from storage in Navajo Reservoir of water not covered by subsection (a) of this section, such contracts shall be subject to the same provision for sharing of available water supply in the event of shortage as in the case of contracts required to be made pursuant to subparagraph (a) of this section. ^ (c) This section shall not be applicable to the water requirements of the existing Fruitland, Hogback, Cudai, and Cambridge Indian irrigation projects, nor to the water required in connection with the extension of the irrigated acreages of the Fruitland and Hogback Indian irrigation projects in a total amount of approximately eleven thousand acres. SEC. 12. (a) None of the project works or structures authorized by this Act shall be so operated as to create, implement, or satisfy any
