was 0.70 inches (4 $) less than the 1961-1990 average. All months but Octobet, January, <br /> February, March, April, and June were below average. Snowpack runoff, as estimated by <br /> totaling November through April precipitation values, was 9.52 inches, which was 1.11 <br /> inches 11 3$) above the 1961-1990 average. <br />The Seneca II precipitation gage measured 17.82 inches thin year. This value is 1.63 <br />inches I6 $) less than the 1981-1998 average. <br />Ground Water <br />Water Levels. Water level data aze presented in Appendix B. Water level reports for data <br />collected since 1991 are presented immediately after the water level hydrograph of all <br />historic data for each respective sell in the same appendix. By presenting all historic <br />data, trends related to seasonal and annual variability and possible mining related <br />impacts are mote clearly evident. Table 3 (Summary of Ground Water Monitoring Wells) is <br />presented ae a reference fox the 'reader. No new wells were drilled in 1997. Water level <br />measurements 'obtained in non-flowing sells aze taken with water level indicator, or in the <br />case of a far shallow alluvial tells, directly from a steel tape. Pressure readings (in <br />• psi) obtained from floring wells with pressure gages are multiplied by 2.31 to obtain head <br />in feet. For the sake of brevity, the prefix that precedes all well names will be dropped <br />throughout this report (except in the case of nested wells with a similar number). As an <br />example, Well SCAL46 will be referred to as Well 46. <br />Alluvium. The alluvial monitoring wells are located along Cor Camp (Wells 46 and 69), <br />Bond (Well 6S), Grassy (Walla 33, 34, 70, and 71), and Little Grassy Creeks (We119 6, 31, <br />31A, and 32). These tells exhibit seasonal fluctuations in rater levels. The opting <br />runoff-infiltration stimulates a water level rise, and ae the drier fall season <br />approaches, rater levels decline. Generally, water levels at most alluvial rolls fell <br />within their historic ranges. Sorever, Walls 46 and 31 exhibited water levels shallower <br />than normal, while Well 70 exhibited rater levels deeper than normal. <br /> Lennox Overburden/Wedge Overburden. The three walla completed in these formations (Wells <br /> SL042, SOV41, and SOV42) exhibit normal seasonal variations, that is, latest eater levels <br /> in the Fall and winter, and highest in the late spring/early summer after the spring <br /> runoff recharge event. This year, all tells displayed aster levels that fell ai thi n their <br /> historic ranges. <br />3 <br />
