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 gallons per minute <br /> (gpm) . Flow was absorbed back into the alluvium within 100 yards <br /> of the source during every observation. As a result, this seep is <br /> not a significant source of surface flow. Conductivity of the <br /> water was stable, ranging from 629 to 768, while pH ranged from 6. 3 <br /> to 8.2 . Use of the water is limited to livestock and wildlife <br /> watering. <br /> Spring #13 : Apache Canyon (Table 3) . This seep originates <br /> from the interface of shale and sandstone. Flow was measured on 8 <br /> of the 11 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) . Spring #15 is a minor <br /> area of seepage from the interface of shale and sandstone below a <br /> coal seam outcrop. No flow or flow of less than 1 gpm was measured <br /> -77- <br />
