Spring #12 : Apache Canyon (Table 2) . This seep originates <br /> from the interface of shale and sandstone. Flow was measured in <br /> each of the samplings ranging from <1 to 5 gpm. Flow was absorbed <br /> back into the alluvium within 100 yards of the source during every <br /> observation. As a result, this seep is not a significant source <br /> of surface flow. Conductivity of the water was stable, ranging <br /> from 629 to 768, while pH ranged from 6. 3 to 8. 2 . Use of the water <br /> is limited to livestock and wildlife watering. <br /> Spring #13 : Apache Canyon (Table 3) : This seep originates <br /> from the interface of shale and sandstone. Flow was measured in <br /> each of the samplings ranging from <1 to 3 gpm. The flow was <br /> absorbed into the alluvium within 50 yards of the source during <br /> each of the 8 observations. As a result, this seep is not a <br /> significant source of surface flow. Water quality measurements of <br /> conductivity range from 700 to 721, while pH ranged from 6. 1 to <br /> 7 . 7 . Use of the seepage is limited to livestock and wildlife <br /> watering. <br /> Spring #14 : Apache Canyon (Table 4) . This is a USGS <br /> developed spring originating from an upper coal seam or interface <br /> between coal and shale or sandstone. Flow could not be measured <br /> because of the associated pond at the site, however, water levels <br /> in the pond appeared to be constant over the monitoring period. <br /> This spring does not contribute to Apache Canyon stream flow_ <br /> because an embankment creating the pond separates the two. <br /> Conductivity ranged from 535 to 739 , while pH ranged from 7 . 4 to <br /> 8 . 9 . Use of the water is limited to livestock and wildlife <br /> watering. <br /> Spring #15 : Ciruela Canyon (Table 5) . This is a minor area <br /> of seepage from the interface of shale and sandstone below a coal <br /> seam outcrop. No flow or flow of less than 1 gpm was measured <br /> during the monitoring period. Water quality was measured on two <br /> occasion with conductivity at 924 to 1054 and pH <br />
