remained fairly constant throughout the last year see Figures 2.7=29g, 2.7-29h and <br />2.7._291) : _. . <br />Water levels in well GP-3 exhibit recovery of its water-level elevation from <br />February, 1986 to March,'1986. Water levels have gradually increased due to flow <br />through a broken valve during the last siic months. - <br />Figure 2.7-29h presents the water-level elevations for the HI well (CP-7) in <br />the far eastern edge of Trapper. Water levels have been very steady in the HI <br />aquifer in this area for the last year. The initial water level is thought to have <br />been affected by the drilling of we 1'1 GP-7.- <br />The water-level plot of well GC-1 in Figure 2.7-29i presents a long-time <br />• period of data for the HI aquifer in this area. The water-level mean for the period <br />of record for well GC-1 has been 6799 feet above MSL. A significant decline in the <br />water-level occurred from mid-1982 through 1983 with a significant- rise following <br />this decline.:.The water level variations are thought to be caused by variations in <br />the recharge to the HI aquifer. <br />Water-level elevation contours have been developed for the NI aquifer in the <br />Trapper Mine area and presented in Map M54B. Contours on this map reflect the <br />September 1986 water .levels. Gradients in the eastern portion of the permit area <br />are close to those observed for the KLM aquifer in [his area of 0.14 ft/ft. <br />Gradients am-much flatter in the area of well GP-3. The HI aquifer discharges to <br />the land surface to the south of well GP-3 and affects gradients in this area. <br />CJ <br />2-523 u REeIISED FEB 13 '87 <br />
