<br />"~ <br />'-..... <br /> <br />January 1960 <br /> <br />San Luis Valley Project, Colorado <br />Closed Basin Division <br /> <br />POTENrIAL ALTERNATE WATER <br />DELIVERY PLANS <br /> <br />Reconnaissance designs and estimates have been prepared, based <br />on four alternative plans for delivery of salvaged waters to the irri- <br />gated lands of the Closed Basin west of the proposed main conveyance <br />channel discussed in the Closed Basin report. The general layout for <br />the four plans is indicated on Drawing 253-504-1800. The studies <br />were based on a reconnaissance report finding that about 65,000 acre- <br />feet of water could be salvaged a.nnuaJ..ly, and assumed that the maximum <br />diversion westward would be 60,000 acre-feet, which is the approximate <br />annual canal deli very requirement for the irr:lgable lands in the <br />vicinity of Mosca-Hooper. <br /> <br />Subsequent and more detailed llydrology studies indicate that <br />amounts considerably- in excess of 60,000 acre-feet could be beneficially <br />used in the irrigated areas west of the proposed main conveyance channel. <br />However, it is cousidered that the reconnaissance estimates of the poten- <br />tial plans discussed below f1\Z'nish reasonable measures of the per acre- <br />foot cost of westward diversion of the salvageable waters. Cost esti- <br />mates were based on JUly 1959 prices. <br /> <br />Plans Studied <br /> <br />Four general plans of disposing of the salvage water on the <br />presently irrigated lands were studied to indicate the cost of such <br />undertakings. All as5U1l1e diversion of salvaged waters at Station 1360 <br />on the proposed main conveyance channel near San Luis Lake. No separate <br />storage works are required to regulate the salvaged waters for delivery <br />to the western lands, as a.ny necessary regulation could be provided by <br />use of San Luis Lake. All follow the same alinement westward. <br /> <br />f' ,~ ..... ~ .~~ {') <br />~J'~h",~UJ <br />
