Lower Arapahoe Denver Basin Atlas No. 3, Plate 5, <br /> Figure 3F <br /> F. Laramie-Fox Hills Denver Basin Atlas No. 4, Plate 3, <br /> Figure 4C <br /> * (Thickness from Plate 4, Figure 3E) - (Thickness from Plate 5 Figure 3F) _ <br /> Thickness of Upper Arapahoe Aquifer <br /> I.E. , to find the thickness of the Upper Arapahoe Aquifer subtract <br /> the thickness value shown in Plate 5, Figure 3F from the thickness <br /> value in Plate 4, Figure 3E. Where there is no overlap between <br /> figures, Figure 3F is "0". <br /> The thicknesses on the figures shall be considered to be the presumptive <br /> thickness of saturated aquifer material as long as the aquifer is confined, <br /> under artesian pressure. The applicant may be required by the State <br /> Engineer to demonstrate that the aquifer is still confined or, if the <br /> aquifer is unconfined, to provide data on the exact location of the water <br /> table. Upon evaluating the location of the water table, the State Engineer <br /> shall determine the thickness of saturated aquifer materials. <br /> Rule 8. Limit on Consumption: In order to assure that no water rights are <br /> materially affected by withdrawals of nontributary ground water from the <br /> Denver Basin Aquifers, no more than 98% of the water withdrawn annually from <br /> a well withdrawing such nontributary ground water shall be consumed. The <br /> applicant must demonstrate to the reasonable satisfaction of the State <br /> Engineer prior to the issuance of the permit that not more than 98% of the <br /> water withdrawn will be consumed. The State Engineer may reasonably require <br /> a permittee to demonstrate periodically that no more than 98% of the water <br /> being withdrawn from the well is being consumed. <br /> Rule 9. Modification of Elevation of the Top or Bottom of Aquifer and the <br /> Number of Feet of Saturated Aquife er r Matials: The following aquifer <br /> characteristics established y t ese ru es (in addition to the specific <br /> yield values set forth in Rule 6) are deemed presumptive: the elevation of <br /> the top or bottom of any of the Denver Basin Aquifers at a specific <br /> .location; and the number of feet of saturated aquifer materials in any of <br /> the Denver Basin Aquifers at a specific location.
