and sandstone below) and 2nd White Sandstone (F coal and sandstone below) are <br />monitored at seven locations. The Lewis Shale is monitored at one location. The Johnson <br />and Pyeatt Gulch alluvial aquifers are monitored at one site in each of these drainages <br />while the Flume Gulch alluvium is monitored at two locations. The 1999 hydrologic <br />monitoring report, Hydro-Engineering, LLC (2000), presents the discussion of the <br />monitoring results through 1999. The table on the pull-out index provides basic well data <br />for all wells monitored in 2000. <br />Springs at Trapper Mine were monitored during 2000 in accordance with the <br />approved monitoring plan. Springs with measured flows of greater than 5 gpm were <br />sampled for full suite water quality parameters. Results of the 2000 spring monitoring are <br />presented in Table B-2. <br />Table 1-1 (page 1-4) presents the pit and well dewatering data and volume of • <br />water used for dust depression for Trapper Mine for 2000. This data shows that, on an <br />average, approximately 28 gpm was pumped from the Trapper Mine pits during 2000. No <br />well dewatering was done in 2000. The average pit pumping rates were 3, 6 and 19 gpm <br />for the A, D and F pits, respectively. This data is useful in interpreting water-level changes <br />and consumptive use. <br />Surface-water flow and quality were monitored at only Flume Gulch (S-1), <br />Johnson, No Name, Oak and East Pyeatt drainages during 2000. The Johnson, No Name, <br />East Buaard, Coyote, West Buaard, Ute, Midd-e Pyeatt, Elk, East Pyeatt, Deer, West <br />Pyeatt, Far East Buaard, Grouse, Sage, Oak, West Flume and Middle Flume drainages are <br />Trapper's NPDES discharge sites 001, 002, 003, 005, 006, 008, 009, 010, 011, 012, 013, • <br />014, 015, 016, 017, 019 and 020, respectively. <br />1-2 <br />
