WATER RESOURCES REVIEW AND CURRENT CONDITIONS STATEMENT
FOR MARCH 2006
Prepared April 4, 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 deficient range during March. Streamflow at
all sites decreased from last month. Generally the Adirondack region sites were in the
normal range while the rest were in the deficient range. Monthly mean flows at all sites
had been in the normal or excessive ranges for the previous five months. The lowest
provisional period-of-record minimum monthly mean discharge for March was recorded
at Schoharie Creek at Prattsville, Ramapo River at Ramapo, and Beaver Kill at Cooks Falls.
Adjustments were made to flows at a few sites due to ice affect and one site was not
included in this report due to extreme ice conditions.
The total New York City reservoir system was at 92.6 percent of capacity on March 30;
normal for this period is 94.4 percent of capacity.
Ithaca--Summary Report
Provisional streamflow conditions at sites monitored and included in this report
for western New York were deficient to normal during March. Streamflow at Cattaraugus
Creek at Gowanda and Tonawanda Creek at Batavia continued to be in the normal range for
the second consecutive month. Streamflow at Oatka Creek at Garbutt and Oneida Creek at
Oneida were in the normal range. All other sites were in the deficinet range for the
month of March.
Coram--Summary Report
Mean flow at Connetquot Brook near Central Islip was in the normal range after being
in the excessive range for five consecutive months.

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.
