WATER RESOURCES REVIEW AND CURRENT CONDITIONS STATEMENT
FOR MARCH 2009
Prepared April 1, 2009
Troy--Summary Report
Provisional streamflow conditions at all sites monitored and included in this report in
eastern New York were in the deficient to excessive range during March. Streamflow at Wallkill
River at Gardiner, Wappinger Creek near Wappingers Falls, and Ramapo River at Ramapo was in the
deficient range for the first consecutive month. Streamflow at all other sites was in the
normal or excessive range for the month. Monthly mean discharges were estimated at three sites
due to ice conditions.
The total New York City reservoir system was at 93.3 percent of capacity on March 31;
normal for this period is 94.8 percent of capacity.
Ithaca--Summary Report
Provisional streamflow conditions at all sites monitored and included in this report for
western New York remained in the normal to excessive range for the month of March. Streamflow
at Chemung River at Chemung was in the normal range for the ninth consecutive month. Streamflow
at Allegheny River at Salamanca was in the normal range for the second consecutive month.
Streamflow at Unadilla River at Rockdale was in the excessive range for the month of March,
after being in the normal range last month. Streamflow at Susquehanna River at Conklin,
Chenango River near Chenango Forks, and Fall Creek at Ithaca was in the normal range for the
third consecutive month. Streamflow at Cattaraugus Creek at Gowanda was in the excessive range
for the second consecutive month. Streamflow at Tonawanda Creek at Batavia, Genesee River at
Wellsville, Oatka Creek at Garbutt, Flint Creek at Phelps, and Oneida Creek at Oneida were in
the normal range after being in the excessive range last month.
Coram--Summary Report

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.
