WATER RESOURCES REVIEW AND CURRENT CONDITIONS STATEMENT
FOR OCTOBER 2004
Prepared November 2, 2004
Troy Subdistrict--Summary Report
Provisional streamflow conditions at sites monitored and included in this report in
eastern New York ranged from deficient to excessive. The percent exceedence decreased
from September to October at all these sites. Those sites in the deficient range were
in northern New York and those in the excessive range were in southeastern New York.
The total New York City reservoir system was at 96.2 percent of capacity on November 1;
normal for this period is 68.8 percent of capacity.
Ithaca Subdistrict--Summary Report
Provisional streamflow conditions at sites monitored and included in this report for
western New York were in the normal range except for Unadilla River at Rockdale,
Susquehanna River at Conklin, Oatka Creek at Garbutt, and Oneida Creek at Oneida which
were in the excessive range.
Coram Subdistrict--Summary Report

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 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, for Cm-622(replacement) are from Cm-46
(adjusted), and for U-1619(replacement) are from U-405 (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.
