WATER RESOURCES REVIEW AND CURRENT CONDITIONS STATEMENT
FOR JANUARY 2008
Prepared February 4, 2008
Troy--Summary Report
Provisional streamflow conditions at all sites monitored and included in this report in
eastern New York were in the excessive to normal range during January. Streamflow at Hoosic
River near Eagle Bridge, Wallkill River at Gardiner, Wappinger Creek near Wappingers Falls,
and Ramapo River at Ramapo was once again in the normal range for the month. All other sites
were in the excessive range for the month, with streamflow at most sites increasing from last
month. One site was not included in this report due to extreme ice conditions.
The total New York City reservoir system was at 91.9 percent of capacity on February 1;
normal for this period is 81.8 percent of capacity.
Ithaca--Summary Report
Provisional streamflow conditions at sites monitored and included in this report for
western New York were in the excessive to normal range during January. Streamflow at
Chemung River at Chemung, Allegheny River at Salamanca, Cattaraugus Creek at Gowanda,
Tonawanda Creek at Batavia, Genesee River at Wellsville, and Oneida Creek at Oneida was in
the normal range after being in the excessive range last month. Streamflow at Susquehanna
River at Conklin and Fall Creek near Ithaca was in the excessive range for the third
consecutive month. Streamflow at Unadilla River at Rockdale and Chenango River near Chenango
Forks was in the excessive range for the second consecutive month. Streamflow at Oatka Creek

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.
