<br /> only one-half this rate in 1990. These declines are due to a <br /> .reduction in the recharge rate to the Third White Sandstone in this <br />... area.. 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 /> P1 have shown an overall decline during 1988 through 1990 from <br /> levels in 1987 (see Figure A-31). Water levels in well P1 stayed <br /> high from 1984 through 1987 because the base flow of Pyeatt Gulch <br /> had increased and had kept the water levels in the alluvium high. <br /> The water levels since September of 1987 are lower than average, <br /> due to declining flow in Pyeatt Gulch caused by the drought <br /> conditions of recent years. Water levels in the Lewis Shale (well <br />• P3, see Figure A-32), which is in contact with the Pyeatt <br /> alluvium, have varied similar to the alluvial aquifer in this <br /> area. Water levels in the Second White Sandstone aquifer near <br /> well P5 have been declining since early 1986, falling <br /> approximately six feet. This indicates that lower recharge rates <br /> to the Second White Sandstone have occurred during this time <br /> period. Water levels in the Third White Sandstone well, P8 (see <br /> Figure A-34) have shown sharp declines since early 1987, dropping <br /> six feet from November 1986 to November 1987 and approximately <br /> twelve additional feet through December 1990. Recharge to the <br /> Third .White Sandstone in this area must- be .lower since 1986. <br />.. These declines are thought to be natural.. - <br /> Water levels of Flume and Johnson Gulch alluvial wells, Coy <br />• <br /> and J1, are presented in Figures A-35 and A-36.
