at 6 . 7 to 7 .4 . This spring is not significant to surface flow and <br /> only has value for livestock and wildlife watering in the spring <br /> of the year. <br /> Spring #16: Ciruela Canyon (Table 6) . Flow originates from <br /> the interface of shale and sandstone and was measurable on several <br /> samplings ranging from <1 to 3 gpm. on all occasions flow was <br /> absorbed into the alluvium within 100 yards of the source and does <br /> not appear to contribute significantly to surface flow. <br /> Conductivity and pH ranged from 110 to 984 and 6 . 4 to 8 . 4 , <br /> respectively. The spring does provide livestock and wildlife <br /> water, however, is not that important due to the location of a <br /> stock pond 200 yards upstream. <br /> Spring #17 : North of Ciruela Canyon (Table 7) . This is a <br /> minor seep from the interface of shale and sandstone located in a <br /> small canyon on the north side of Highway 12 . Flow was measured <br /> on 8 of the 11 samplings at 1 or less gpm. Conductivity ranged <br /> from 820 to 1148 , and pH ranged from 5 . 9 to 8 . 7 . In all cases, <br /> the flow was absorbed into the alluvium within 200 yards of the <br /> source contributing very little to surface flow. The seep is <br /> useful for livestock and wildlife watering. <br /> Spring #18 : Parras Canyon (Table 8) . The spring originates <br /> from the interface of shale and sandstone measuring from 1 to 3 <br /> gpm. During the August 1984 sampling flow was measured at 50 gpm, <br /> however, localized thunderstorms were contributing to surface <br /> runoff in the upper reaches of the canyon. Conductivity and pH <br /> ranged from 420 to 560 and 5. 9 to 8 . 4 , respectively. Present use <br /> of the spring is livestock and wildlife watering, while <br /> contributing little to overall surface flow. <br /> Spring #19 : At Middle Fork of Purgatoire (Table 9) . Flow <br /> originating from fractured shale and sandstone was measured at <1 <br /> to 4 gpm on several samplings. In all cases, the flow was absorbed <br /> within 300 yards of the source. Conductivity ranged <br />
