WATER RESOURCES REVIEW AND CURRENT CONDITIONS STATEMENT
FOR JULY 2005
Prepared August 2, 2005
Troy Subdistrict--Summary Report
Provisional streamflow conditions at sites monitored and included in this report in
eastern New York were in the normal to excessive range. Streamflow at Wappinger Creek
near Wappinggers Falls, East Branch Delaware River at Margaretville, Beaver Kill at
Cooks Falls, and Oquaga Creek at Deposit increased into the normal range after being
in the deficient range for two months. Streamflow at Hudson River at Hadley and Ausable
River at Au Sable Forks remained in the excessive range for the second consecutive
month.
The total New York City reservoir system was at 86.0 percent of capacity on August 1;
normal for this period is 90.1 percent of capacity.
Ithaca Subdistrict--Summary Report
Provisional streamflow conditions at sites monitored and included in this report
for western New York ranged from normal to excessive during July. Streamflow at
Susquehanna River at Conklin, Allegheny River at Salamanca, Cattaraugus Creek at Gowanda,
and Genesee River at Wellsville increased from deficient into the normal range. Streamflow
at Flint Creek at Phelps increased from normal into the excessive range for the month.
Streamflow at all other sites was in the normal range for July.
Coram Subdistrict--Summary Report
Mean flow at Connetquot Brook near Central Islip was in the normal range for the
fifth consecutive month.

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.

INDEX STREAMFLOW STATIONS
(Reference period 1971-2000)
## Reference period is 1978-2000
# Note: Flow statistics based on data collected through July 31, 2005.
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.
