Article III
1. To accomplish the purposes of this compact, as set forth in Article I, the following adjustments in the operation of irrigation facilities on Costilla Creek, and in the use of water diverted, stored and regulated thereby, are made:
(a) The quantity of water delivered for use in the two states by direct flow ditches in the Costilla-Garcia Area and by the Cerro Canal is based on a duty of water of one cubic foot per second of time for each eighty (80) acres, to be applied in the order of priority; provided, however, that this adjustment in each instance is based on the acreage as determined by the court in decreeing the water rights for the Costilla-Garcia Area, and in the case of the Cerro Canal such basis shall apply to eight thousand (8,000) acres of land. In order to better maintain a usable head for the diversion of water for beneficial consumptive use the adjusted maximum diversion rate under the water right of each of the ditches supplying water for the Costilla-Garcia Area in Colorado is not less than one cubic foot per second of time.
(b) There is transferred from certain ditches in the Costilla-Garcia Area twenty-four and fifty-two hundredths (24.52) cubic feet per second of time of direct flow water rights, which rights of use are held by the water company or its successors in title, to the headgate of the Cerro Canal. The twenty-four and fifty-two hundredths (24.52) cubic feet of water per second of time hereby transferred represents an evaluation of these rights after adjustment in the duty of water, pursuant to subsection (a) of this Article, and includes a reduction thereof to compensate for increased use of direct flow water which otherwise would have been possible under these rights by this transfer.
(c) Except for the rights to store water from Costilla Creek in Eastdale Reservoir No. 1 as hereinafter provided, all diversion and storage rights from Costilla Creek for Eastdale Reservoirs No. 1 and No. 2 are relinquished and the water decreed thereunder is returned to the creek for use in accordance with the plan of integrated operation effectuated by this compact.
ese rights by this transfer.
(c) Except for the rights to store water from Costilla Creek in Eastdale Reservoir No. 1 as hereinafter provided, all diversion and storage rights from Costilla Creek for Eastdale Reservoirs No. 1 and No. 2 are relinquished and the water decreed thereunder is returned to the creek for use in accordance with the plan of integrated operation effectuated by this compact.
(d) The Cerro Canal direct flow permit shall be seventy-five and forty-eight hundredths (75.48) cubic feet per second of time.
(e) There is transferred to and made available for the irrigation of lands in Colorado a portion of the Costilla Reservoir complement of the Costilla Reservoir System Safe Yield in order that the storage of water in that reservoir may be made for the benefit of water users in both Colorado and New Mexico under the provisions of this compact for the allocations of water and the operation of facilities.
2. Each state grants for the benefit of the other and its water users the rights to change the points of diversion of water from Costilla Creek, to divert water from the stream in one state for use in the other and to store water in one state for the irrigation of lands in the other, insofar as the exercise of such rights may be necessary to effectuate the provisions of this Article and to comply with the terms of this compact.
3. The water company has consented to and approved the adjustments contained in this Article; and such consent and approval shall be evidenced in writing and filed with the commission.
Article IV
The apportionment and allocation of the use of Costilla Creek water shall be as follows:
(a) There is allocated for diversion from the natural flow of Costilla Creek and its tributaries sufficient water for beneficial use on meadow and pasture lands above Costilla Reservoir in New Mexico to the extent and in the manner now prevailing in that area.
(b) There is allocated for diversion from the natural flow of Costilla Creek and its tributaries thirteen and forty-two hundredths (13.42) cubic feet of water per second of time for beneficial use on lands in the Amalia Area in New Mexico.
(c) In addition to allocations made in subsections (e), (f) and (g) of this Article, there is allocated for diversion from the natural flow of Costilla Creek fifty and sixty-two hundredths (50.62) cubic feet of water per second of time for Colorado and eighty-nine and eight hundredths (89.08) cubic feet of water per second of time for New Mexico, subject to adjustment as provided in Article V (e), and such water shall be delivered for beneficial use in the two states in accordance with the schedules and under the conditions set forth in Article V.
(d) There is allocated for diversion from the natural flow of Costilla Creek sufficient water to provide each year one thousand (1,000) acre-feet of stored water in Eastdale Reservoir No. 1, such water to be delivered as provided in Article V.
(e) There is allocated for diversion to Colorado thirty-six and five-tenths per cent (36.5%) and to New Mexico sixty-three and five-tenths per cent (63.5%) of the water stored by Costilla Reservoir for release therefrom for irrigation purposes each year, subject to adjustment as provided in Article V (e) and such water shall be delivered for beneficial use in the two states on a parity basis in accordance with the provisions of Article V. By "parity basis" is meant that neither state shall enjoy a priority of right of use.
(f) There is allocated for beneficial use in each of the states of Colorado and New Mexico one-half of the surplus water, as defined in Article II (p), to be delivered as provided in Article V.

The actual discharges of Costilla Creek at the Canyon Mouth Gaging Station at which the various blocks of direct flow water become effective shall equal the flows set forth in column (1) increased by the transmission losses necessary to deliver those flows to the headgates of the respective direct flow ditches diverting in New Mexico.
The delivery of ditch water at the boundary shall equal the allocation set forth in columns (2a) and (2b) reduced by the transmission losses between the headgate of the ditch and the point where the ditch crosses the boundary. The allocations to be delivered to Colorado through the Cerro Canal represent, except as otherwise indicated in column (5) of the table above, 36.5 percent of those blocks of direct flow water of the Costilla Reservoir System which are subject to adjustment as provided in subsection (e) of this article.
The provisions of article III (1)(a) shall not be applicable to the Colorado allocation of 5.08 C.F.S. which is transferred from the Acequia Madre to the Cerro Canal by this amendment to the Costilla Creek compact and shall not be applicable to the 0.8 C.F.S. which is transferred from Colorado to New Mexico by this amendment to the Costilla Creek compact.
The above table is compiled on the basis of the delivery to Colorado at the boundary of thirty-six and five-tenths percent (36.5%) of all direct flow water of the Costilla Reservoir System diverted by the Cerro Canal and the delivery at the boundary of all other direct flow water allocated to Colorado, in the order of priority, all such deliveries to be adjusted for transmission losses. In the event of change in the usable capacity of the Costilla Reservoir, Colorado's share of all direct flow water of the Costilla Reservoir System diverted by the Cerro Canal, to be delivered at the boundary and adjusted for transmission losses, shall be determined by the percentages set forth in column (4) of the table which appears in subsection (e) of this article.
(c) During the storage season, no water shall be diverted under direct flow rights unless there is water in excess of the demand of all operating reservoirs for water from Costilla Creek for storage.
(d) In order to assure the most efficient utilization of the available water supply, the filling of Eastdale Reservoir No. 1 from Costilla Creek shall be commenced as early in the spring as possible and shall be completed as soon thereafter as possible. The Cerro Canal or any other ditch which may be provided for that purpose shall be used, insofar as practicable, to convey the water from the Canyon Mouth to Eastdale Reservoir No. 1. During any season when the commission determines that there will be no surplus water, any diversions, waste or spill from any canal or canals supplying Eastdale Reservoir No. 1 will be charged to the quantity of water diverted for delivery to said reservoir.
