• levels <br /> consistent with each other but show an eight foot drop in a is <br /> from 1988. The water levels had risen at a fast rate in the KLM <br /> aquifer in this area through 1987 (see Figure A-16, well GF3) . <br /> Water levels appear to have stabilized during 1988. The 1989 <br /> water levels were stable with a small decline from the 1988 levels. <br /> Water levels in well GF4 continued to rise until June, 1987 and <br /> remained steady until December 1987 when levels rose for the first <br /> three quarters of 1988. Levels remained steady for the remainder <br /> of 1988 and showed little change in 1989 ( see Figure A-17) . Most <br /> of the recent water-level fluctuation in the KLM and HI aquifers <br /> at the GF wells is thought to be caused by the upgradient mining <br /> releasing ground water along with recovery and stabilization from <br /> • mine dewatering . Present levels may be close to pre-mine levels. <br /> Figure A-18 shows that water level in backfill well GF5 has <br /> steadily risen since its installation . Water levels since the <br /> latter part of 1987 may indicate that levels may have peaked and <br /> are beginning to stabilize in the backfill aquifer near well GF5. <br /> Pre-mine water levels may have been greater in the HI aquifer at <br /> site GF5. The average water levels in well GF6 for 1988 and 1989 <br /> have been fairly stable after declining steadily from levels for <br /> 1986 and 1987 ( see Figure A- 19) . Water levels in the OR aquifer <br /> are thought to be reflecting historical precipitation influences. <br /> Upgradient mining in 1983 could have caused some water-level <br /> fluctuations. Overall trends are thought to have been caused by <br /> natural influences. <br /> i <br /> 2-9 <br />
