Show COSTILLA CREEK COMPACT 91 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. (e) The Commission shall estimate each year the Safe Yield of Costilla Reservoir System and its component parts as far in advance of the Irrigation Season as possible, and shall review and revise such estimates from time to time as may be necessary. In the event the Usable Capacity of the Costilla Reservoir changes, the average safe yield and the equitable division thereof between the States shall be determined in accordance with the following table: Division of Safe Yield Usable Capacity of Costilla Reservoir (1) Average Annual Safe Yield (acre-feet) (2) Colorado New Mexico (acre-feet) (3) (percent) (4) (acre-feet) (5) (percent) (6) Intermediate quantities shall be computed by proportionate parts. In. the event of change in the Usable Capacity of the Costilla Reservoir, the Costilla Reservoir complement of the Costilla Res- ervoir System Safe Yield shall be divided between Colorado and New Mexico in accordance with the percentages given in Columns 4 and 6, respectively, of the above table. Each State may draw from the Reservoir in accordance with the allocations made herein, up to its proportion of the Costilla Res- ervoir complement of the Costilla Reservoir System Safe Yield and its proportion of Temporary Storage and no more. Colorado may call for the delivery of its share thereof at any of the specified Points of Interstate Delivery. Deliveries of water from Costilla Reservoir to the Canyon Mouth shall be adjusted for transmission losses, if any, between the two points. Deliveries to Colorado at the Boundary shall be further adjusted for transmission losses from the Canyon Mouth to the respective Points of Interstate Delivery. Water stored in Costilla Reservoir and not released during the current season shall not be held over to the credit of either State 0..............________ 1,800 1,510 83.9 290 16.1 1.0Q0..........______...... 3,400 2,000 58.8 1,400 41.2 2,000........................ 4,900 2,450 50.0 2,450 50.0 3,000................______ 6,400 2,910 45.5 3,490 54.5 4,000........................ 7,900 3,370 42.7 4,530 57.3 5,000........................ 9,300 3,800 40.9 5,500 59.1 6,000................... 10,700 4,220 39.4 6,480 60.6 7,000._...................... 12,000 4,620 38.5 7,380 61.5 8,000..................... 13,200 4,990 37.8 8,210 62.2 9,000..................... 14,300 5,320 37.2 8,980 62.8 10,000........................ 15,200 5,600 36.8 9,600 63.2 11,000........................ 16,000 5,840 36.5 10,160 63.5 12,000_______............... 16,600 6,020 36.3 10,580 63.7 13,000...................... 17,000 6,140 36.1 10,860 63.9 14,000........................ 17,400 6,270 36.0 11,130 64.0 15,000........................ 17,700 6,360 35.9 11,340 64.1 15,700.................... 17,900 6,420 35.9 11,480 64.1 |
