. Ground Water <br />Water Levels. Water level data are presented in Appendix B. Water <br />level reports for data collected since 1998 are presented immediately <br />after the water level hydrograph of all historic data for each <br />respective well. By presenting all historic data, trends related to <br />seasonal and annual variability and possible mining related impacts are <br />more clearly evident. Table 3 (Summary of Ground Water Monitoring <br />Wells) is presented as a reference for the reader. No wells were <br />drilled or abandoned this year. The ground water monitoring program is <br />presented on pages 7-341/342 of the Seneca II PAP. Water level <br />measurements obtained in non-flowing wells are taken with water level <br />' indicator, or in the case of a few shallow alluvial wells, directly from <br />a steel tape. Pressure readings (in psi) obtained from flowing wells <br />with pressure gages are multiplied by 2.31 to obtain head in feet. For <br />the sake of brevity, the prefix that precedes all well names will be <br />dropped throughout this report (except in the case of nested wells with <br />• a similar number). As an example, Well SCAL46 will be referred to as <br />We11 46. <br />- Alluvium. The alluvial monitoring wells are located along Cow Camp <br />(Wells 46 and 69), Bond (Well 66), Grassy (Wells 33, 34, 70, and 71), <br />and Little Grassy Creeks (Wells 6, 31, 31A, and 32). These wells <br />exhibit seasonal fluctuations in water levels. The spring runoff- <br />infiltration stimulates a water level rise, and as the drier fall season <br />approaches, water levels decline. Water levels are also affected by the <br />absence or presence of beaver dams in the adjacent stream. Generally, <br />water levels at most alluvial wells fell within their historic ranges. <br />However, Wells 69 and 71 exhibited their lowest water levels on record <br />this year. Wells 32, 33, 34, and 70 exhibited this year water levels <br />closely approaching historic lows. <br />- Lennox Overburden/Wadge Overburden. The three wells completed in <br />these formations (Wells SLO42, SOV41, and SOV42) usually exhibit normal <br />• seasonal variations, that is, lowest water levels in the fall and <br />winter, and highest in the late spring/early summer after the spring <br />3 <br />
