since early 1986, falling approximately six feet. This indicates <br />that lower recharge rates to the Second White Sandstone have <br />occurred during this period. Water levels in the Third White <br />Sandstone well, P8 (Figure A-34) have shown sharp declines since <br />early 1987, dropping six feet from November 1986 to November 1987 <br />and approximately twelve additional feet through December 1990. <br />Fluctuations in the water level seen in 1990 and 1991 are most <br />likely due to seasonal change. Recharge to the Third White <br />Sandstone in this area must be lower since 1986. These declines <br />are thought to be natural. <br />Water levels for the Johnson and Flume Gulch alluvial wells, <br />J1 and Coy, are presented in Figures A-35 and A-36. The plot of J1 <br />• water levels show fairly steady values. The level for well J1 <br />during December 1990 does show a small rise in water level, but in <br />1991 the level returns to values seen prior to 1990. Mine <br />discharge into Johnson Gulch has maintained water levels in this <br />alluvial system during dry climatic conditions. The water level in <br />alluvial well COY (Figure A-36) remained fairly steady from May <br />1986 to September 1987. The water level has declined nearly twenty <br />feet from September 1987 to September 1990 reflecting the decline <br />in recharge to this alluvium. The water level was still declining <br />in 1991, but at a slower rate. Figure A-8 also shows this steady <br />decline in water levels for alluvial well GC3. <br />Figure A-37 presents the water-level elevation data for well <br />81-03a. Water levels presented for the monitoring period, based on <br />pressure readings, have considerable scatter but seem to be <br />2-13 <br />
