• <br />• <br />Sanborn Creek Mine 1995 Annual Hydrologic Report <br />parameters, pH, conductivity, and temperature would indicate <br />monitoring of surface water collected in the depression. <br />Spring 2 is possible re-emergence of water in a small ephemeral <br />drainage channel. Flows, if any, are recorded in the spring and <br />summer. The field parameters are similar to surface water. <br />Springs 3, 4, 5, & 6 are also possible re-emergence of surface <br />water in a small ephemeral drainage, with similar characteristics <br />of flow diminishing from spring to summer, moderate pH, low <br />conductivity, and variation in temperature. <br />Of all the Springs 1-6, only Springs 4 and 5 consistently have <br />flow. Springs 2 and 6, located in the ephemeral drainage channels <br />below Springs 4 and 5, are dry following spring run-off. Although <br />the actual locations of the six springs have not been surveyed, and <br />only Spring 1 may be within the permit area, all six springs are <br />within the Hawksnest Creek drainage area. <br />Spring 7 is in the hill-side, cut-bank of the Coal Gulch trail. <br />While the historical data for Spring 7 indicates it is typically <br />dry, monitoring indicates ground flow in the spring months, <br />resulting in high conductivity measurements. <br />Spring 8, the flow from the abandoned Oliver Mine, had recorded <br />flow during all of the monitoring events. The monitoring data <br />collected is indicative of a ground water source. <br />Spring 9 is a spring or seep at the base of <br />in the Unnamed Gulch. Flow has been nearly <br />low rates.

It was originally in the facilities <br />area below Old Highway 133. No flow was recorded for Spring 11 in <br />1992 and 1993. In May of 1994, water began to collect in the road <br />cut above Old Highway 133. This was monitored and an elevated <br />conductivity and temperature was measured. Flow was recorded in <br />June and July of 1994, but the conductivity and temperature <br />measurements decreased. <br />Water damage to the pavement of Old Highway 133 had occurred next <br />to the re-emergence of Spring 11, and between the July and August <br />monitoring events of 1994, the Colorado Department of <br />Transportation performed maintenance of the roadway and ditch in <br />the area of Springs 10 & 11. Both Springs 10 and 11 were dry at <br />• <br />
