. data for well GP8. Well GP8 is completed in the KLM aquifer <br /> approximately 25 feet away from well GP7. Water levels in well <br /> GP8 compare well with KLM aquifer wells GA2 and GP4. The changes <br /> are thought to be a reflection of natural declines in the KLM <br /> aquifer. Water-level data for well GPB is tabulated in Table A- <br /> 8. Water-level elevations for Third White Sandstone well GP9 are <br /> shown on Figure A-30. Levels were fairly steady in well GP9 <br /> through 1987. The 1988 water level shows a drop of nearly three <br /> feet which is thought to be caused by a reduction in the recharge <br /> rate. Water-level data for well GP9 is tabulated in Table A-8. <br /> Water-level data for the P series wells is presented in <br /> Tables A-8 and A-9 of Appendix A. Water levels in alluvial well <br /> PI have shown a decline during 1988 from levels in 1987 (see <br />• <br /> Figure A-31). Water levels in well P1 stayed high from 1984 <br /> through 1987 because the base flow of Pyeatt Gulch had increased <br /> and had kept the water levels in the alluvium high. The water <br /> levels since September of 1987 are lower than average, due to <br /> declining flow in Pyeatt Gulch probably caused by the 1988 <br /> drought. Water levels in the Lewis Shale (well P3, see Figure A- <br /> 32>, which is in contact with the Pyeatt alluvium, have varied <br /> similar to the alluvial aquifer in this area. Water levels in <br /> the Second White Sandstone aquifer near well PS have been <br /> declining since early 1986, falling approximately five feet. <br /> This indicates that lower recharge rates to the Second White <br /> Sandstone have occurred during this time period. Water levels in <br /> the Third White Sandstone well, P8 (see Figure A-34) have shown <br /> sharp declines since early 1987, dropping six feet from November <br />2-11 <br />
