Show 90 INTERSTATE COMPACTS DELIVERIES OF DIRECT FLOW WATER TO COLORADO DURING IRRIGATION SEASON 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 (I) 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 Bound- ary of all other direct flow water allocated to Colorado, in the order of priority, all such deliveries to be adjusted for trans- mission 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 trans- mission 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 avail- able water supply, the filling of Eastdale Keservoir No. 1 from Costilla Creek shall be commenced as early in the spring as pos- sible and shall be completed as soon thereafter as possible.

Incremental allocation is 10.13% of the usable discharge when usable discharge is less than 25.00 c.f.s. This 4.70 c.f.s. is not a part of the Colorado allocation of the direct flow water of the Costilla Reservoir System and is not subject to adjustment in the event of a change in the usable capacity of Costilla Reservoir. Incremental alloca- tion is 18.8% of the usable discharge when usable dis- charge is less than 25 c.f.s. This 4.70 c.f.s. allocated to Colorado for delivery through the Cerro Canal is 5.50 c.f.s. of the original 6.55 c.f.s. allocated to Colorado for delivery through the Acequia Madre less 0.8 c.f.s. correction for losses. This 0.38 c.f.s. is not a part of the Colorado allocation of the direct flow water of the Costilla Reservoir System and is not subject to adjustment in the event of a change in the usable capacity of Costilla Reservoir. Incremental alloca- tion is 3.26% of the usable discharge in excess of 25.38 c.f.s. and less than 36.88 c.f.s. Incremental allocation is 35.11% of the usable discharge in excess of 25.38 c.f.s. and less than 36.88 c.f.s. Incremental allocation is 100% of the usable discharge in excess of 37.62 c.f.s. and less than 38.62 c.f.s. Incremental allocation is 36.5% of the usable discharge in excess of 38.62 c.f.s. and less than 44.76 c.f.s. Incremental allocation is 100% of the usable discharge in excess of 44.91 c.f.s. and less than 50.91 c.f.s. Incremental allocation is 11.18% of the usable discharge in excess of 55.35 c.f.s. and less than 56.48 c.f.s. Incremental allocation is 100% of the usable discharge in excess of 60.48 c.f.s. and less than 61.48 c.f.s. At usable creek discharge of 64.22 c.f.s. the Cerro Canal direct flow permit becomes operative after 1,000 acre- feet has been stored in Eastdale Reservoir No. 1. Incremental allocation is 36.5% of the usable discharge in excess of 64.22 c.f.s. and less than 139.70 c.f.s. |
