2.05.4 (2)(c). Approximately 54 acres of the WFC property in the permit area could be irdgated <br />in the future after bond release if additional water was available and the landowner decided to <br />use it This is based on the area where slopes are milder than 6K 1V as seen on Mao 2.05.4-5. <br />Since waterwould be brought from the main pipe on the high point of the property, all lower areas <br />can be easily irrigated if WFC or a future landowner decides to make more water available for <br />this area. <br />4) The Morgan property south of BB Road and west of 2700 Road of 107.96 acres that has been <br />designated in the pre -mine studies as part "Irrigated Pasture - Hay "and part Irrigated Pasture. As <br />discussed previously, the soils in this area are primarily Barx (98E), therefore. all of the land has <br />been considered prime farmland soils and since the water has been made available for irrigation <br />all of this tract is considered prime farmlanand will be restored to Irrigated Cropland (IC). <br />See the revised Map 2.04.10 -1 Pre -Mine Vegetation, which includes an aerial image from <br />1998. Much of this parcel was previously Flood irrigated and harvested as an alfalfa field. <br />Prairie dog holes are evident in the middle of the field as well as some non - irrigated <br />mounds but much of the field appears healthy. The western portion of the parcel shows <br />in the baseline vegetation study as irrigated pasture where grass is the main component <br />of the vegetation. <br />It has been observed that the Morgan's management style for this field before mining <br />commenced was to Flood irrigate the field by corrugated pipe and furrow strips that ran <br />the 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 <br />the field. The aerial photo indicates some of the furrows were in excess of 1,280 feet. <br />It was not uncommon for the water to be turned on for ten days or more to totally cover <br />the acreage. Porosity of the soil also plays a big part in how long a watering set will take <br />and how long a field may be. <br />Morgan has e i According to recent calculations performed by NRCS (See <br />Attachment 2.05.4(2)(e) -71.60 shares of water would be needed to irrigate 97.5 acres of <br />Morgan property using sideroll sprinklers. This is based on years of NRCS experience <br />in the area There are a numberof variables that are taken into accountwhen determining <br />PR -06 May 2010 2.05.4(2)(e) - 7 <br />
