<br />The plan provides for maintaining, by year-round :pumping, <br />ground-water levels at least 8 fee'\; b..1ow the ground surface over <br />selected areas totaling aboUt 108,600 acres, with resul'ta.nt water <br />salvagel"of abou't 86, 500 acre-feet annually. An average 15,200 acre- <br />feet also would be salvaged annually by providing outlets for surface <br />waters. The hydrologic analyses indicate that, under the plan and. on <br />the basis of records to date, delivery of salvaged. water to the Compact <br />station at Lobatos over a 35-year :period would permit Colorado to <br />achieve a debit-free Compact status; but no firm forecast of the period <br />which would be required can be made. The studies :f'urther indicate that, <br />at the end. of that period, unless Colorado's ability to deliver Rio <br />Grande flowa has improved, an average of 59,200 acre-feet annually of <br />the salvaged water would be required 'to maintain Colorado in debit-free <br />status. <br /> <br />The locations of the adopted water salvage areas, the proposed. <br />Mishak !akes and Ala.mosa National Wildlife Refuges and 'the primary features <br />of the water salvage plan, are indicated on the :perspective Drawing 253- <br />504-1829. <br /> <br />The water salvage plan would. include the following features: <br /> <br />1. About 129 deep wells and pumping plants located throughout <br />the water salvage areas, each having continuous water yields averaging <br />from 0.5 c.f.s. to 3.5 c.f.s. '.l'rAn"11Ji.ssion lines, substations, and cr\;her <br />facilities required for operation of 'the :pumping plants and control of <br />'the pumping operations. About 110 miles of transmission lines would be <br />required. <br /> <br />2. A Main Conveyance ChaImel about 44 miles long, beginning <br />at the east boundary of the proposed. M1shak !akes National Wildlife Refuge <br />and running southeaster~ to the west side of San Luis Lake and then south <br />to the Rio Grande. The Main Conveyance Channel would have a design capacity <br />of 34 c.f.s. at the upper end, increase in size to 158 c.f.s. near San Luis <br />!ake, have that capacity 'to the junction with the East Side Conveyance <br />ChaImel near U. S. Highway 160, and have a capacity of 210 c.f.s. from the <br />junction to its outlet into the Rio Grande. <br /> <br />3. A channel about one-half mile long to COImect the Main <br />Conveyance Channel with San Luis Lake to :permit maintenance of the lake <br />at essentially a cons'ta.nt level for fish and. wildlife and recrea'tion <br />purposes and for temporary storage of salvaged waters in the lake when <br />circums'ta.nces make such action desirable. The connecting channel would <br />have a capacity of 158 c.f.s. <br /> <br />4. An East Side Conveyance Channel, about 11 miles long, would <br />collect the salvaged water from the salvage area J.y1rig on the east side <br />of the Main Conveyance ChaImel and. south of San Luis Lake and deliver it <br />to the Main Conveyance Channel near U. S. Highway 160. The capacity of <br />the channel would increase downstream from 10 c.f.s to 52 c.f.s. <br /> <br />3 <br /> <br />to., '-.- <br /><../... ...... <br /> <br />.
