It is then estimated that this <br />water level can be maintained with asteady-star pumping rate of approximately ]txl gptn. The <br />wear being pumped froth the West Pit would be metered, and the well meters would have a <br />totalizer. Permit applications for the use of these wells in the West Pit will be submitted to dte <br />State Engineer's Office. <br />The water proposed to be pumped from the West Pit would either be pumped dit~ectly to the <br />Rocky Mountain Farms via a pipeline:, t)r it would be pumped to a staging pond lutated adjacent <br />to the West Pit (Figure 1). In either case, the water would he used for irrigation at the Rocky <br />Mountain Farms. The reason far the staging pond is that the pipeline will also continue to be used <br />to deliver augmentation water from the pocky Mountain Farms to Rito Saco. Therefore, when the <br />pipel%ne is being used W deliver augmentation wear, water from the West Pit will be pumped to <br />the staging pond and stored until the pipoline is free to moos water from the West Pit to the Rocky <br />Mountain Farms. <br />As shown in Figure 1, the staging pond; located adjacent to the West Pit will be sized tv allow <br />pumping of the West Pit to continue tu»~tarrupted, so that water levels can be maintained at the <br />desired elevation in the West Pit. This pit will be lined with 8Q-ttv] HDPE to control seepage <br />losses. <br />When the water is delivered from the West Pit to the Rocky Mountain Farms, it will be swred in <br />a series of lined ponds located adjatznt to an existing irrigation reservoir (Figure 2). The ponds <br />will be lined with 80-mll HDPL to comrol txxpage loss of the water. The ponds are designed w <br />score 33,540,000 gallons (102.9 ac-ft), which is an amount equivalent w pumping the West Pit <br />welts at the anticipated steady-start: ran (i00 gpm) fora 9-month period. This capacity will allow <br />continuous pumping of West Pit water to`the Rceky Mounrain Farms on ayear-round basis, with <br />water stored in the wintertime being urek in the subsequent irrigation season. <br />The Rtxky Mountain Forma Listoritally has used deep wells and Trinchera Irrigntiba Company <br />water for its irrigation water source. Theac waters are very low in total dessolved solids, itx:ludittg <br />sulfate and manganese. 'the average quality of ground waur from the West Pit meets agriculwral <br />standards for all cvnstituents but thtoridei, TDS end manganese. It is, therefore, proposed that <br />the current irrigation water supply at the Rocky Mountain Farms be mixed with the Nest Pit water <br />in a ratio sufFicicnt to meet all agricultural standards. 'fhe mixed water would dtett be pumped <br />i <br />through ttrc center pivots for irrigation on the Rocky Mountain Farms. Initially, it is etxpected that <br />-z- <br />
