<br /> <br />0'.,: <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />Feasibility Studies <br /> <br />The foregoing evaluation has shown that the res'tx>ration of <br />the channels of the Rio Grande and its tributW:ies would be economically <br />feasible undertakings and that further, more detailed studies of feasi- <br />bility grade are warranted. The costs and time required for three <br />phases of the overall study have been estimated. <br /> <br />The initial phase would be the detailed studies of restoring <br />the 12-mile reach of the Rio Grande from the mouth of the proposed <br />Closed Basin Division Conveyance Channel to a point 4 miles below the <br />mciuth of the Conejos River. This channel work would insure the delivery <br />of water, salvaged fram the qlosed Basin, with the minimum of trans- <br />mission losses. A feasibility report on this phase could be completed <br />in 2 years at a cost of $105,000. ' <br /> <br />Feasibility studies of channel restoration for the remain- <br />ing reach of the Rio Grande, the Conejos and San Antonio Rivers, and <br />La Jara, Alamosa, and Rock Creeks would be prepared as the second <br />phase. The cost of performing these studies and preparing a report <br />thereon would be 4;268,000, and the work would be accomplished witl1in <br />four fiscal years. <br /> <br />The third phase of the investigation would be carried on <br />simultaneously with the other two. Because of Rio Grande Compact, <br />provisions, it will be necessary to analyze the operation of the Rio <br />Grande and Conejos Divisions in coordination with each other and with <br />water salvage in the Closed, Basin DiviSion and channel restoration. <br />The Wagon Wheel Gap dam and reservoir was studied in the 1955 report <br />on the Rio Grande and ~eminuche ~ass Divisions. Feasibility studies <br />on the Closed Basin Divisionwerecpresented in the 1963 report on <br />that potential development. Both of those reports will have to be <br />updated and the additional studies performed. This phase of the work <br />will require an expenditure of $111,000 during a period of four fis- <br />cal years. <br /> <br />6 <br />
