Somerset Mining Company <br />1994 Annual Hydrologic Report <br />marking to be Approximate Spring Location. Actual monitoring <br />locations have been marked on the ground, and monitored at the same <br />locations since. <br />Sprinq 1 is a depression neax a grove of aspen trees. The <br />depression may have contained water when it was monitored previous <br />to 1993. Data have not recorded a flow. The other field <br />parameters, pH, conductivity, and temperature would indicate <br />_ previous 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. Other than the high pH measurements for 1993, which are , <br />suspect, 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. The only unusual data <br />are the high conductivity measurements for Springs 2 & 3 in August <br />1983. <br />Sprinq 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 in 1993 and 1994 indicates ground flow in the <br />spring months, resulting in high conductivity measurements. <br />Spring 8; the flow from the Oliver Mine, had recorded flow during <br />all of the monitoring events, although the snow and ice in January <br />and February of 1994 prevented measurement. The monitoring data <br />collected during 1992, 1993 and 1994 compares quite well with the <br />historical data. While the flow measurements during this period <br />were lower than the historical data, the constant flow rate of 12 <br />gpm for the historical data is suspect. Variations in pH were from <br />6.9 to 9 (9.9 in September 1992 is suspect) compared to 6.9 to 9 <br />for 1983 to 1987. Conductivity measured 1800 to 4900 umhos/cm <br />compared to 1900 to 4000 umhos/cm, indicative of a ground water <br />source. Variation in temperature is less with warm temperatures in <br />the winter months, also indicative of a ground water source. ~. <br />Spring 9 is a spring or seep at the base of the landslide feature <br />in the Dnnamed Gulch. Flow has been nearly continual, but at very <br />low rates, with a few exceptions. High conductivity measurements <br />indicate ground flow, but conclusions based on temperature patterns <br />are not clear. Spring 10 is a spring or seep at the base of the <br />colluvium just above Old Highway 133 at the west end of the Hawk's <br />Nest east site. Data for Spring 10 is similar to Spring 9. <br />Spring 11 was covered during the reclamation of the Hawk's Nest <br />East Mine by the Division. It was originally in the facilities <br />11 <br />
