<br /> water levels show fairly steady values. The level for well J1 <br /> during December 1990 does show a small rise in water level. Mine <br />_ ...discharge into.. Johnson Gulch-has maintained water level in this <br /> alluvial system during these dry conditions. The Flume Gulch <br /> alluvial aquifer is also monitored with alluvial well GC3. The <br /> water level in alluvial well COY (see Figure A-35) remained fairly <br /> steady from May 1986 to September 1987. The water level has <br /> declined nearly twenty feet from September 1987 to September 1990 <br /> reflecting the decline in recharge to the alluvium. Figure A-8 <br /> shows this steady decline in water levels for alluvial well GC3. <br /> Well 81-03a is completed in the Third White Sandstone. <br /> Figure A-37 presents the water-level elevation data for well 81- <br />• 03a. Well head pressures for flowing well 81-03a were converted <br /> to water-level elevation. Water levels presented for the <br /> monitoring period have considerable scatter but seams to be <br /> gradually rising after a significant drop in late 1989. <br /> The GLUX-1 well was completed in the First White Sandstone in <br />September 1988 in order to monitor pre-mine conditions upgradient <br />of the Lux domestic well prior to mining in Browning and Colt <br />pits. Water levels for well GLUX-1 are presented on Figure A-38 <br />and have declined 2.6 feet in the last six months of 1990. This <br />decline is probably due to the dry conditions during the last feu <br />years .that has caused similar natural declines in several. other <br />White Sandstone wells. ~ . <br />• <br />2-14 <br />
