Springs #26 and #27 : Pratt Canyon (Tables 17 and 18) . <br /> Springs in the canyon originate from the interface of shale and <br /> sandstone. Flow ranged from dry to 3 gpm with pH and conductivity <br /> measured at 8. 1 to 8. 2 and 381 to 589, respectively. <br /> Spring #28• Sawmill Canyon (Table 19) One spring was <br /> identified in Sawmill Canyon originating from a shale outcrop. <br /> Flow was less than one gpm with pH of 7 . 7 and conductivity of 563 <br /> during 1988 and was dry during 1989 . <br /> DISCUSSION <br /> With the exception of Santistevan and Wet Canyons, water <br /> encountered during the spring and seep survey is the result of <br /> seepage contributing little, if any, to sustained surface flow. <br /> Water originates from the interfaces of shales, sandstones and <br /> minor coal seams not proposed to be mined by WFC. <br /> Analysis of the water indicates a mineralized condition with <br /> varying quality and quantity, responding directly to amounts of <br /> precipitation received in the drainage. Currently, uses of the <br /> water are for livestock and wildlife with no irrigation or domestic <br /> supply. <br />
