WATER RESOURCES REVIEW AND CURRENT CONDITIONS STATEMENT
FOR FEBRUARY 2004
Prepared March 2, 2004
Troy Subdistrict--Summary Report
Provisional streamflow conditions at sites monitored and included in this report in
eastern New York were in the deficient to normal range. Minor adjustments were made to
flows at some sites due to ice effect. Extreme ice conditions were reported for 11 sites
and therefore these sites were not included in this report. Conditions at all sites herein
decreased from the previous month. Streamflow at East Branch Delaware River at Margaretville
in the Catskill Mountain region was at its 95% exceedence discharge.
The total New York City reservoir system was at 91.7 percent of capacity on March 1;
normal for this period is 83.5 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 deficient range Susquehanna River at Conklin, Unadilla River
at Rockdale, Chenango River at Chenango Forks, Allegheny River at Salamanca, Tonawanda
Creek at Batavia, Genesee River at Wellsville, Oatka Creek at Garbutt, Oneida Creek at
Oneida, and Fall Creek at Ithaca. Sites at Chemung River at Chemung, Cattaraugus Creek
at Gowanda, and Flint Creek at Phelps were in the normal range. All sites were adjusted
for ice effect.
Coram Subdistrict--Summary Report
Mean flow at Connetquot Brook near Central Islip was in the normal range for February
after eight consecutive months in the excessive range.

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.
