remained fairly constant throughout Che last year (see Figures 2.7=29g, 2.7-29h and <br />2.7.-29i): <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 six months. - <br />Figure 2.7-29h presents the water -level elevations for the HI well (GP -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 well 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 />CJ <br />Water -level elevation contours have been developed for the HI 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 this area of 0.14 ft/ft. <br />Gradients -are -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 />2-523 u REVISED FEB 13 '87 <br />
