Also presented is an assessment of the significance of the springs and seeps on surface • <br />flows, irrigation practices, livestock watering and domestic use. <br />Since 1984, additional monitoring has been conducted o^ an annual basis during the <br />month of August of each year. During these monitoring periods, measurements of pH, <br />conductivity and temperature were made. Flow from each spring and seep was visually <br />estimated. Data for each of the locations monitored has been presented yearly in the <br />Annual Hydrology Report (AHR). Eight additional springs were identified in 1988 <br />within the Golden Eagle expanded mining area. Locations of all identified springs and <br />seeps are shown on Map 7, Regional Hydrology and the 1988 monitoring results <br />provided in Table 11, Results of Field Spring and Seep Inventory. <br />With the possible exception of Santisteven Canyon, water encountered during the survey <br />is the result of seepage contributing little if any to sustained surface flow. Water <br />originates from the interfaces of shales, sandstones and minor coal seams that were never <br />mined by Basin Resources. Analysis of the water indicates a mineralized condition oC <br />varying quality and quantity, responding directly to amounts of precipitation received <br />within the drainage area with drought conditions totally interrupting flows. The limited <br />flows observed result in only limited potential use of the flows for wildlife watering and <br />no use for irrigation or domestic supply. <br />The 2002 AHR concluded that assessments of springs and seeps indicate that mine • <br />operations have not affected current uses of these springs and seeps. Theoretically, there <br />is some potential for the loss of spring and seep flows into the underground mine <br />workings by fracture systems developed through laud subsidence. However, no springs <br />overlie the Golden Eagle Mine. Springs I5, 20, and 21 are nearest to the mine workings <br />and no impacts to flow have been observed. As mining ceased in 1995, no further <br />impacts due to subsidence aze expected. Annual monitoring of springs and seeps is no <br />longer required. <br />TR-54 2.04-21 (Revised 4/2003) • <br />
