The sources of <br /> irrigation include both surface application from the Godding , <br /> Daily and Plumb Ditch as well as groundwater from the alluvium <br /> of Boulder Creek . Mr. Nelson has an efficient irrigation <br /> system and a factor of 70% was assumed to determine the amount <br /> of surface irrigation water consumed by the area . Return flow <br /> from other areas is not a major factor due to physical con- <br /> ditions of the area . Table 1 summarizes the historic water <br /> use on the property. <br /> Water Requirements After Reclamation <br /> The process of mining gravel , as mentioned previously, will <br /> form three ponds of varying water surface area. A major <br /> portion of the land outside the mining area is expected to <br /> retain itS present land use character and will be irrigated as <br /> it has historically . <br /> To compensate for the additional water loss caused by open <br /> lake evaporation over irrigated pasture, a proportionate <br /> number of shares from the Godding , Daily and Plumb Ditch will <br /> be attached to .each lake formed by the mining operation. The <br /> number of shares to be attached was determined by computing <br /> the average and critical year consumptive yield of one share <br /> used on Mr., Nelson ' s property and providing the number of <br />
