INDEX OBSERVATION WELLS
The observation-well network generally reflects conditions in water-table sand and gravel
aquifers and does not necessarily reflect conditions in confined and bedrock aquifers. Water
levels in Sa-1100, and S1810 have been affected by changes in ground-water withdrawals or
sewering. Water level in feet below land-surface datum unless site noted with * which
indicates reference to sea level or ** which indicates water level in feet above land-
surface datum. Statistics used for A-654(replacement) are from A-636 and those for Cm-622
(replacement) are from Cm-46 (adjusted).

NOTES, DEFINITIONS, ETC.
Percent exceedence is, for example, the percentage of November monthly mean discharges for
period of record equal to or greater than the current November monthly mean discharge.
Statistics for the "Index Streamflow Stations" table are for the 30-year reference period
1971-2000. All other statistics used in report are based on the period of record at the site.
Median = 50th percentile, which means that, for the period of record included in the analysis,
50% of the values are greater than the median and 50% are less.
Deficient range = values below the 25th percentile - for the period of record included in the
analysis, 75% of the values are greater and 25% are less than this value.
Excessive range = values above the 75th percentile - for the period of record included in the
analysis, 25% of the values are greater and 75% are less than this value.
Normal range = values between the 25th and 75th percentiles.
