The QR water-level map at Trapper Mine was very similar in 2008 to the 2007 water- <br />level elevations. Gradients and flow directions for the QR aquifer in 2008 are similar to those <br />observed in 2007. <br />Map No. 2-2 presents the water-level elevation contours for the HI aquifer in the Fall of <br />2008. Wells GC-1, GF-4, GP-3, GP-7, and GMP-1, which are completed in the HI aquifer, and <br />backfill wells GF-5 and GF-7, were used in the development of this map. Wells GF-5 and GF-7 are <br />completed in the backfill in the area where the H and I coal seams were mined. Flow direction in <br />the HI aquifer has been changed mainly near the A pit near well GF-4. The overall flow regime in <br />this aquifer is northerly, similar to that observed in 2007 (see Hydro-Engineering, 2008). The <br />ground-water gradient between the backfill aquifer and the un-mined HI aquifer downgradient is <br />relatively flat as it is in the QR backfill. The contours in the HI aquifer have also been changed on <br />the east side where the A pit dewatering in 2008 likely has caused water level declines near this pit. <br />0 The F and Z pits were used to mine the I seam in 2008 while the H seam was mined in the A and G <br />pits. <br />The 3rd White Sandstone aquifer water-level elevations are presented on Map No. 2-3. <br />Wells GC-2, P-8 and GP-9 were used in the development of this map. Flow direction in the 3rd <br />White Sandstone is mainly toward the north, as expected. The 2008 contours are very similar to <br />those observed from the last few years. <br />• <br />Trapper Mining Company 2-9 <br />2008 Annual Report
