Oblique aerial photographs were taken by Mr. Ranney on October 27. 2004 <br />and reviewed by Kent Gorham of the CDMG on November 17, 2004- This former <br />underground mine has been idle or served as a loadout since underground operations <br />ceased nearly 15 years ago. <br />Hydrologic Balance <br />Pond 8 at the RDA. pond 7 at the eastern edge of the facility area, and pond 4 near the <br />development waste pile were clearly visible in many of the photographs reviewed. All of <br />these ponds held water, ranging from a small puddle at pond 4 to significant water held in <br />pond S. Pond 7 held water in the eastem end and a significant sediment delta is noted at <br />the western end (inlet). <br />~od• '" i'i~wt ~3 t ~~~ <br />~~ ~ ~:-- <br />~'~, <br />~.-~.~ <br />~_ , <br />sbMw ~u.~~^.. ,, <br />v t ~ ~~ J.. <br />~ q. <br />Eight days has past since the grading of the RDA evas observed during an on-the-ground <br />inspection. Progress appears significant, as shown in the photograph below. Material has <br />been pushed to the north, resulting in the development of a broad terrace bench in the <br />center of the operational surface near the top of the fourth bench. The operator should <br />ensure that drainage continues to be directed toward the two downdrains that flank the valley <br />fill during modifications necessary to prevent flow over the constructed face of the fill. <br />
