Spring #17: North of Ciruela Canyon (Table 7) . This is a minor seep from the interface of shale and sandstone located in a small canyon on the north side of Highway 12. Flow was measured on 8 of the 9 samplings at 1 or less gpm. Conductivity ranged from 820 to 1148, and pH ranged fran 5.9 to 8.7. In all cases, the flow was absorbed into the alluvium within 200 yards of the source contributing very little to surface flow. The seep is valuable for livestock and wildlife watering. Spring #18: Parras Canyon (Table 8) . The spring originates fran the interface of shale and sandstone measuring from 1 to 3 gpm. During the August 1984 sampling flow was measured at 50 gpm, however, localized thunderstorms were contributing to surface runoff in the upper reaches of the canyon. Conductivity and pH ranged from 420 to 560 and 5.9 to 8.4, respectively. Present use of the spring is livestock and wildlife watering, while contributing little to overall surface flow. Spring #19: At Middle Fork of Purgatoire (Table 9) . Flow originating fran fractured shale and sandstone was measured at <1 to 4 gpm on 7 of the 9 samplings. In all cases, the flaw was absorbed within 300 yards of the source. Conductivity ranged fran 360 to 889, while pH ranged fran 6.6 to 8. 3. This seep is utilized for livestock and wildlife watering while contributing little to surface flow. Spring #20: Santistevan Canyon Flume (Table 10) . Quality and quantity of 3 Santistevan Canyon springs were monitored collectively at the flume location placed in the laver canyon. Flows originating frau fractured shales and sandstone were measured between 5 and 50 gpm. Quality ranged fran 504 to 583 conductivity and 6.6 to 8.7 pH. Current use is livestock and wildlife watering and for aesthetics as the flow creates a stream running through the ranchette development in the canyon. These springs are a valuable contribution to surface flaw making Santistevan Canyon a perennial stream.
