WATER RESOURCES REVIEW AND CURRENT CONDITIONS STATEMENT
FOR JANUARY 2009
Prepared February 3, 2009
Troy--Summary Report
Provisional streamflow conditions at all sites monitored and included in this report in
eastern New York were in the normal range during January. Streamflow at all sites were in
the normal range after being in the excessive range last month. Monthly mean discharges
were estimated at most sites due to ice conditions and seven sites were not included in
this report due to extreme ice conditions.
The total New York City reservoir system was at 87.1 percent of capacity on January 30;
normal for this period is 81.6 percent of capacity.
Ithaca--Summary Report
Provisional streamflow conditions at all sites monitored and included in this report for
western New York were in the normal to deficient range during January. Streamflow at Chemung
River at Chemung was in the normal range for the seventh consecutive month. Streamflow at
Oneida Creek at Oneida was in the normal range for the third consecutive month. Streamflow
at Allegheny River at Salamanca was in the deficient range after being in the excessive
range last month. All other sites were in the normal range after being in the excessive
range last month. Monthly mean discharges were estimated at most sites due to ice conditions.
Coram--Summary Report
Provisional streamflow at Connetquot Brook near Central Islip was in the excessive range
for the second consecutive month.

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 (adjusted) 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.
All published data for A-654 prior to 2006 water year should be adjusted by +1.00 ft due to measuring point correction.

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.
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.
