<br />Following completion of the pump testing and leaky aquifer testing we <br /> <br />will construct models of the system based on the information gathered in <br /> <br />the testing pilase of the def:lnH~ plan st1"d:les. We would hope to confit'1ll <br /> <br />by these models the capacities and spadnfi, of wells in the stage 1 <br /> <br />portion of the projec.t. We will also construct III water quality model to <br /> <br />predict the quality of vater that could b~, delivered to the Rio Grande. <br /> <br />As you are aware, Article III of the Rio Grande Compact limits salvaged <br /> <br />vaters which can be credited to Colorado ..s a part of its compact require- <br /> <br />mente. The percent of sodium ions must be less thari 45 vhen the TPS <br /> <br />exceede 350 p/m in the salvaged vater. <br /> <br />The act authorizes the Secretary to improve the Rio Grande channel as a <br /> <br />part of the Closed Basin Division. This improvement viII begin at the <br /> <br />mouth of th~ Main Conveyance Channel and e~tend to the Colorado-~ev <br /> <br />)4,ax1ro 1I!:"1If'.. lfn.... r"t' v111 ,lllljllll~l1"'P r.Rrry1ne ~Jo11vRe,p.d WArP-TA in "he lUo <br /> <br />Grande vithput flooding of surrounding lands and minimize losses of <br /> <br /> <br />salvaged vaters. We have scheduled approximately Ib months for the <br /> <br />channel rectification studies of the definite plan report, because the <br /> <br />channel rectification Vas included in the project au.horization on the <br /> <br />basis of very preliminary and brief consideration. No report of this <br /> <br />conSideration vas published. We do not know the capacity of the river <br /> <br />to accept the salvaged waters, but expect that very little channel <br /> <br />rectification work will physically be clone on the lr1ver. Channel <br /> <br />rectification implies a lesser amount of york than channelization, and <br /> <br />we expect to keep all river channel modifications to the absolute mini- <br />mum.
