length of the field. Typically, the watering would take place at the beginning of each <br />harvest cycle. Massive amounts (up to 70 shares of water or 2 CFS for the eastern 22.89 <br />acre field) were used and needed to traverse portions of the field. This is called "Pulse <br />Flow Irrigation" and it is needed to push the water in the furrows to the furthest point in the <br />field. The aerial photo indicates some of the furrows were in excess of 1,280 feet. It was <br />not uncommon for the water to be turned on for ten days or more to totally cover the <br />acreage. Porosity of the soil also plays a big part in how long a watering set will take and <br />how long a field may be. <br />• According to calculations performed in the March 8, 2010 letter from NRCS (See <br />Attachment 2.05.4(2)(e) -11), 60 shares of water would be needed to irrigate 97.5 acres <br />of Morgan property using sideroll sprinklers. This is based on years of NRCS experience <br />in the area. There are a number of variables that are taken into account when determining <br />this ratio, however, the most important item is the management. This results in an overall <br />ratio for all of the fields combined of 1.62 acres per water share in the CC Ditch. Some <br />fields will be irrigated by sideroll and others by flood. Based on this ratio, 66.4 shares <br />overall would be needed to irrigate the entire Morgan property in the permit area (107.96 <br />acres). Detailed calculations for separate ratios can be seen inthe designs of the irrigation <br />system for each Morgan field in Attachment 2.05.4(2)(e) -7. <br />• As of April, 2010, Morgan has leased 62 shares of water (or whatever is necessary) to <br />WFC to irrigate all of their property within the permit area. The lease addendum letter <br />concerning the additional water is included in Attachment 2.05.4(2)(e) -7. Therefore, the <br />entire Morgan -owned area in the permit will be reclaimed as Irrigated Cropland (IC) and <br />all areas within the Morgan property will be considered prime farmland. WFC will replace <br />all topsoil in the entire property to its original depth. See revised Section 2.05.4(2)(d) <br />Topsoil Redistribution. All soils replaced on this property will meet the prime farmland soil <br />specifications outlined in Section 2.05.4(2)(d). <br />5) The parcel of 29.36 acres in the extreme southeast corner of the permit area, which is now <br />owned by Western Fuels As of the start of 2008, this parcel has not yet been reclaimed since it <br />contains the overburden main stockpile for the mine. <br />• This tract was originally classified as Irrigated Pasture (IP) in the pre -mine land use but no <br />water came with the WFC purchase of this tract and none is allocated for future use. <br />• Portions of the tract were "Flood Irrigated" in the past. <br />(Revised: PR -06) 2.05.4(2)(e) - 11 <br />
