H coal seam while the F and Z pits mine the I seam. H pit mined the G seam. The 3rd White <br />Sandstone (G coal and sandstone below) and 2nd White Sandstone (F coal and sandstone below) aze <br />monitored at six locations. The Lewis Shale is monitored at one location. The Johnson and Pyeatt <br />Gulch alluvial aquifers aze monitored at one site in each of these drainages while the Flume Gulch <br />alluvium is monitored at two locations. The 2004 hydrologic monitoring report, Hydro-Engineering, <br />LLC (2005), presents the discussion of the monitoring results through 2004. The table on the pull- <br />out index provides basic well data for all wells monitored in 2005. Wells GB-1, GB-2, GB-5, GF-1, <br />GF-2 and GF-3 were not required to be monitored. <br />Springs at Trapper Mine were monitored during 2005 in accordance with the approved <br />monitoring plan. Springs with measured flows of greater than 5 gpm were sampled for full suite <br />water quality pazameters. Results of the 2005 spring monitoring aze presented in Table B-2 in <br />Appendix B. <br />Table 1-1 (page 1-4) presents the pit and well dewatering data and volume of water used <br />for dust depression for Trapper Mine for 2005. This data shows that, on an average, approximately <br />15.4 gpm was pumped from the Trapper Mine pits during 2005. Well dewatering was started in <br />September of 2002 in the G pit. The average well pumping rate for 2005 was 28.3 gpm for the G pit <br />well dewatering. This data is useful in interpreting water-level changes and consumptive use. <br />Surface-water flow and quality were monitored at only Flume Gulch (S-1), Johnson, No <br />Name, East Pyeatt, Middle Flume, East Flume and East Middle Flume drainages during 2005.
