WATER RESOURCES REVIEW AND CURRENT CONDITIONS STATEMENT
FOR MAY 2005
Prepared June 2, 2005
Troy Subdistrict--Summary Report
Provisional streamflow conditions at sites monitored and included in this report in
eastern New York decreased from the previous month. Streamflow, which had been in the
excessive to normal range during April, decreased into the deficient range at many sites.
Hudson River at Hadley, Schoharie Creek at Prattsille, West Branch Delaware River at Walton,
Sandy Creek near Adams, and Little Salmon River at Bombay were in the normal range for May.
The total New York City reservoir system was at 96.2 percent of capacity on June 1;
normal for this period is 100.0 percent of capacity.
Ithaca Subdistrict--Summary Report
Provisional streamflow conditions at all sites monitored and included in this report
for western New York decreased from the previous month. Streamflow, which had been in the
excessive range at most sites during April, decreased into the deficient range at many
sites. Only Tonawanda Creek at Batavia, Oatka Creek at Garbutt, Flint Creek at Phelps, and
Oneida Creek at Oneida were in the normal range for May.
Coram Subdistrict--Summary Report
Mean flow at Connetquot Brook near Central Islip was in the normal range for the
third consecutive month.

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 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.

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.
