WATER RESOURCES REVIEW AND CURRENT CONDITIONS STATEMENT
FOR AUGUST 2003
Prepared September 2, 2003
Troy Subdistrict--Summary Report
Provisional streamflow conditions at sites monitored and included in this report in
eastern New York were in the excessive range except at Oquaga Creek at Deposit and
Independence River at Donnattsburg which were in the normal range. The second highest
(provisional) period-of-record (1918 to date) monthly mean discharge for August was
recorded at Mohawk River at Cohoes. Conditions at Wappinger Creek near Wappingers Falls
and East Branch Delaware River at Margaretville were in the excessive range for the
third consecutive month.
The total New York City reservoir system was at 97.0 percent of capacity on August 29;
normal for this period is 81.8 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 excessive range at all sites. The recorded monthly means
for Allegheny River at Salamanca and Genesee River at Wellsville were the highest of
record. Monthly means for Chemung River at Chemung, Flint Creek at Phelps, Oneida Creek
at Oneida, and Unadilla River at Rockdale were the third highest of record.
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, those for Cm-622(replacement) are from Cm-46 (adjusted), and those
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.
