WATER RESOURCES REVIEW AND CURRENT CONDITIONS STATEMENT
FOR FEBRUARY 2006
Prepared March 2, 2006
Troy--Summary Report
Provisional streamflow conditions at all sites monitored and included in this report in
eastern New York were in the normal to excessive range during February. Streamflow at
Canajoharie Creek near Canajoharie, Schoharie Creek at Prattsville, Wallkill River at
Gardiner, Ramapo River at Ramapo, and West Branch Delaware River at Walton decreased from
the excessive range into the normal range. All other sites remained in the excessive range
and streamflow at Hudson River near Newcomb and West Branch Oswegatchie River near
Harrisville continued to be in the excessive range for the sixth consecutive month.
Adjustments were made to flows at a few sites due to ice affect and five sites were not
included in this report due to extreme ice conditions.
The total New York City reservoir system was at 96.7 percent of capacity on February
28; normal for this period is 83.4 percent of capacity.
Ithaca--Summary Report
Provisional streamflow conditions at sites monitored and included in this report
for western New York were normal to excessive during February. Streamflow at Chenango River
at Chenango Forks and Oneida Creek at Oneida continued to be in the excessive range for the
fifth consecutive month. Streamflow at Susquehanna River at Conklin, Unadilla River at
Rockdale, Oatka Creek at Garbutt, and Flint Creek at Phelps continued to be in the excessive
range for the second consecutive month. All other sites were in the normal range for the
month of February.
Coram--Summary Report
Mean flow at Connetquot Brook near Central Islip was in the excessive range for the
fifth 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 December monthly mean discharges for
period of record equal to or greater than the current December 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.
