Monitoring Sites; and the Table of Contents of Appendices C through E <br />have all been revised to correlate the old site (and map) name to the <br />new (Paradox) computer name. The new computer name will be used <br />throughout the following text. <br />The Tie- Across Haul Road (formerly associated with the Seneca II -W Mine) <br />was transferred to the Hayden Gulch Terminal (CDRMS Permit C -92 -081) on <br />January 4, 2012. <br />Meteorological Data <br />Data from the National Climatic Data Center's Hayden Station is used <br />here to evaluate the precipitation trend. These data are provided in <br />Appendix Al. Precipitation data is summarized on Table 2. For this year, <br />12.80 inches of precipitation was measured, which is 4.54 inches (26 %) <br />below the 1971 -2000 average, 17.34 inches. All months except November, <br />February, July and September were below average. Snowpack runoff, as <br />estimated by totaling November through March precipitation values, was <br />5.35 inches, which was 1.83 inches (260) below the 1971 -2000 average, <br />7.18 inches. <br />Ground Water <br />Water Levels. Water levels (i.e., depth to water from ground surface) <br />for all wells that are in the current monitoring program are presented <br />in Appendix C. Hydrographs of all historic data for each well are <br />presented prior to the water level reports (for all data since 2005) for <br />each respective well in the same appendix. By presenting all historic <br />data, trends related to seasonal and annual variability are more clearly <br />evident. Water level measurements are taken with an electrical water <br />level indicator, or in the case of a few shallow alluvial wells, <br />directly from a steel tape. Site information, including sampling <br />frequencies, is presented in Table 3, Summary of Ground Water Monitoring <br />Wells. Ground water level monitoring frequencies are listed in Table 1 <br />of Appendix 15 -3a in the Seneca II -W PAP. <br />2 <br />
