No water <br />has ever been seen emanating from the highwall, although the 5 feet excavation at the bottom has <br />uncovered groundwater which had to be covered up as required by the permit. See the enclosed <br />picture of the mined highwall on the next page. This provides more perspective upon the depths of <br />groundwater which are present on the upper portions of the upper terrace gravel. <br />Haldorson Sand and Gravel Mine 33 <br />
