Figure 3. This chart shows the ground water level measured in feet below the land surface in a monitoring well in Oxford, Maine, from October 1998 to September 1999. These data are collected and are reported monthly by the U.S. Geological Survey. The line graph shows fairly consistent water levels from October 1998 to February 1999. The beginning of ground water recharge conditions due to snow melt and rainstorms is represented by the rise in the curve from February to March. The drought of the summer of 1999 is reflected in the decreasing slope of the line from March to August. Following the strong rainfall during the month of September 1999, ground water levels have begun to rise again due to recharge by the heavy precipitation events during that month.
