INDEX OBSERVATION WELLS
Water levels in 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 (adjusted) prior to 2003, for Cm-622
(replacement) are from Cm-46(adjusted) prior to 2003, and for U-1619(replacement) are from U-405(adjusted) prior to 2003.
All published data for A-654 prior to 2006 water year should be adjusted by +1.00 ft due to measuring point correction.

NOTES, DEFINITIONS, ETC.
Percent exceedence is, for example, the percentage of December monthly mean discharges for
period of record equal to or greater than the current December monthly mean discharge.
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.
