site iti each of these drainages while the Flumee Gulch alluvium is .~ <br />monitored at two loczitions. The 1990 hydrologic monitoring report, <br />Hydro-Engineering (3/91), presents the discussion of the <br />monitoring results through 1990. The table or. the blue pull-out <br />index provides basin, well data for all wells monitored in 1991. <br />Spoil springs with flows greater than 5 gpn~are required to be <br />monitored to furthei define the ground-water quality. The flows <br />from all spoil springs were all less than 5 gp~~ during 1991. <br />Table 1-1 (page 1-3) presents the pit and w=11 dewatering data <br />and volume of water used for dust depression for Trapper Mine for <br />1991. This data shocis that, on an average, approximately 90 and 37 <br />gpm were pumped from the Trapper Mine pits ant! dewatering wells, <br />~ respectively. CThe tcital dewatering from D pit in 1981 was greater <br />' than two times the 1990 ~ This data is usef~il in interpreting • <br />water-level changes 'and consumptive use. <br />Surface-water flow and quality have been monitored at the <br />Flume, West Buzzard, Johnson, No Name, Coyote, Dte and Elk <br />drainages during 1991.
