5.2 Irrigation Designs For Irrigated Cropland areas, all irrigation designs have been based on calculations from the local NRCS representative, Jim Boyd. Irrigation will be accomplished with side roll sprinklers and flood irrigation supplied by 4 inch to 10 inch supply lines. Water will be applied at a rate based on the irrigation calculations presented in Attachment 2.05.4(2)(e) -7 (IC). The irrigation designs for the Morgan property IC areas use a different field labeling than the pre- mine field designations. The post -mine fields and brief descriptions of the irrigation type (sideroll or flood) can be seen on Map 2.05.4 -5, with the old Morgan field labels shown for comparison. Field A Northwest field on Morgan property; irrigated by sideroll; see Sideroll Irrigation Design in Attachment 2.05.4(2)(e) -7. Field B Southwest field on Morgan property; irrigated by sideroll; see Sideroll Irrigation - Morgan Design in Attachment 2.05.4(2)(e) -7. Field C North - central field on Morgan property; irrigated by sideroll; see Sideroll Irrigation Design - Morgan in Attachment 2.05.4(2)(e) -7. Field D Northeast field (Sunshine Corner) on Morgan property; flood irrigated; see Flood Irrigation Design - Morgan Sunshine Corner in Attachment 2.05.4(2)(e) -7. Field E South - central triangular field on Morgan property; flood irrigated; see Flood Irrigation Design - Morgan Triangle in Attachment 2.05.4(2)(e) -7. The NRCS supplied full calculations for irrigating 97.5 acres of the Morgan property, using 50 shares of the CCC Ditch. The Morgans have agreed to supply 62 shares of water and supplement it with whatever is needed in a particular year, to ensure that their entire property within the permit area is irrigated. This letter is provided in Attachment 2.05.4(2)(e) -7. Map 2.05.4 -5 shows the layout of each of the 3 sideroll irrigated fields proposed for the Morgan property, and the 2 flood irrigated areas on the Moran property. PR -06 June 2010 2.05.4(2)(e) - 39
