<br />The following i temswill be determined to carry out this <br />procedure for the Llano unit: <br /> <br />1. Diversions at Velardo Diversion Dam. <br />2 . Consumptive use. <br />3. Return flow. <br /> <br />Pojoaque Unit. The :l:'resently irrigated 1.il.nds of the pojoaque <br />Unit will be supplied supplemental water from the Nambe Fa.lls Reservoir.. <br />Since the unit will oonta.in no new lands it will be assumed that there <br />will be no :tncrease in direct diversions ofna.tura.l flow; and only <br />aocounting for storage effects, adjusted for return flow from diversions <br />from storage, will be required. <br /> <br />The following items will be determined for the Pojoaque Unit in <br />carrying out the accounting probedure: <br /> <br />1. Inflow to Nambe Falls Reservoir. <br />2 . Change in storage in Nambe,:'Falls Reservoir. <br />3. Increased eva,potranspiration losses from Nambe Falls <br />Reservoir areas. <br />4. Release from Nambe Falls Reservoir. <br />5 . Total diversions. <br />6. Consumptive use. <br />7. Return flow. <br /> <br />Municipal and Industria~ Use by Albuquerque <br /> <br />Albuquerque is now securing its water from about 82 wells, <br />located both in the river valley and on the :mesas as far as 6 miles <br />from the river valley. The State Engineer of New Mexico Ms declared <br />the Middle Rio Grande Va:lleya ground-water basin, tn,us exereising <br />jurisdiction over new ground"-water appropriations in that area. The <br />state Engineer, in administering the basin, contemplates that the city <br />will retire water-r:l.ghtland, or participate in the San Juan-C1la:ma. <br />Project, to the extent of the future depletion of riwr:'flows resulting <br />from the operation of new wells; such depletion to be detezmined by <br />application of the Theis none.qu:l.1ibrium equation and appropriate values <br />of the storage and tra.nsmissibility coefficients of the aquifer determined <br />from geological and hydrolog:Lcal studies. <br /> <br />.~!e're are two possib~e :methods of delivering the city.s share. of <br />the imported water. The first and simplest method, with respect to accoUnting, <br />would be a direct surfaoe water diversion of San Juan-C1la:ma. water carried in <br />the Rio Gra.nde. Such a direct diversion could be made in the immediate <br />vicinity of Albuquerque, or at any convenient location. The second and more <br />complicated method of delivery would be for the city to continue to use <br />wells. The San Juan-Chama. water would then be used to compensate, on a daily <br />or short-period basis, for the depletion of the flow of the Rio Gra.nde caused <br />by wi thdre.wa.l of water through such new wells. <br /> <br />24 <br /> <br />Rev. 2/25/63 <br />
