WATER RESOURCES REVIEW AND CURRENT CONDITIONS STATEMENT
FOR JANUARY 2002
Prepared February 4, 2002
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. Mean flows at Hudson River at
Hadley, Mohawk River at Cohoes, and Wallkill River at Gardiner were in the deficient
range for the sixth consecutive month, at Wappinger Creek near Wappingers Falls for
the fourth consecutive month, and at Schoharie Creek at Prattsville for the third
consecutive month. However, the mean flow was in the normal range at West Branch
Delaware River at Walton after five consecutive months in the deficient range and at
East Branch Delaware River at Margaretville after two consecutive months in the
deficient range. Adjustments were made to flows at some sites due to ice affect.
Extreme ice conditions were reported for Schoharie Creek at Prattsville and Ausable
River at Au Sable Forks, and therefore values for these sites were estimated in this
report.
On January 18, the New York State Department of Environmental Conservation upgraded
the following 10 upstate counties from a drought watch to a drought warning: Albany,
Columbia, Fulton, Herkimer, Montgomery, Oneida, Rensselaer, Saratoga, Schenectady, and
Washington. Also, a drought watch was issued for the 5 boroughs of New York City and
Nassau and Suffolk County on Long Island. The total New York City reservoir system was
at 42.0 percent of capacity on January 31; normal for this period is 81.7 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 at all sites except those in the Upper
Susquehanna River Basin, which remained in the deficient range. Susquehanna River at
Conklin was deficient for the fourth consecutive month and Unadilla River at Rockdale
was deficient for the fifth consecutive month. Minor ice adjustments were made at some
sites.
Coram Subdistrict--Summary Report
Mean flow at Connetquot Brook near Central Islip was in the deficient 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 N1259, N1616, Q1249, Sa-1100, S1806, and 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.

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.
