N/D indicates no data	NDR indicates no data received at time of report
DOWN = Water level is lower than that reported for last month or year
UP = Water level is higher than that reported for last month or year
Shaded block indicates this month is a new recorded maximum or minimum
Year refers to water year, October 1 - September 30.

* Value for well is computed using less than the full period of record because of a change in well hydraulics, or nearby non-climatic hydrologic stress.
^ Below normal conditions for well SO-2 are due to nearby pumping.
+ Well MR-1364 was affected by the Pymatuning Earthquake on Sept. 25, 1998. Record adjusted to compute current conditions shown on map.

Note: Water levels from well MG-225 are being collected but not reported in this monthly summary, because they are not comparable to historical levels due to changes in ground-water pumping.
