WATER RESOURCES REVIEW AND CURRENT CONDITIONS STATEMENT
FOR MARCH 2004
Prepared April 2, 2004
Troy Subdistrict--Summary Report
Provisional streamflow conditions at sites monitored and included in this report in
eastern New York were in the normal range except for Wappinger Creek near Wappingers Falls
which was in the deficient range for the second consecutive month and Sandy Creek near Adams
which was in the excessive range. Minor adjustments were made to flows at some sites due to
ice effect, mainly in the first week of the month. Significant ice conditions were reported
for four sites and therefore these sites were not included in this report. Conditions at all
sites herein increased or stayed the same as the previous month.
The total New York City reservoir system was at 97.2 percent of capacity on March 30;
normal for this period is 94.4 percent of capacity.
Ithaca Subdistrict--Summary Report
Provisional streamflow conditions at sites monitored and included in this report for
western New York were in the normal to excessive range. Streamflow at all sites increased
from the previous month as a result of the complete meltdown of the winter snowpack.
Streamflow conditions at Susquehanna River at Conklin, Chemung River at Chemung, Unadilla
River at Rockdale, and Oneida Creek at Oneida were in the normal range, while all other
sites were in the excessive range.
Coram Subdistrict--Summary Report
Mean flow at Connetquot Brook near Central Islip was in the normal range for March, as
it was for the previous month of February. Prior to that, mean flow was in the excessive
range for eight 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, for Cm-622(replacement) are from Cm-46
(adjusted), and for U-1619(replacement) are from U-405 (adjusted).

# Note: Flow statistics based on data collected through March 31, 2004.
NOTES, DEFINITIONS, ETC.
Percent exceedence is, for example, the percentage of November monthly mean discharges for
period of record equal to or greater than the current November 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.
