WATER RESOURCES REVIEW AND CURRENT CONDITIONS STATEMENT
FOR JUNE 2006
Prepared July 7, 2006
Troy--Summary Report
Provisional streamflow conditions at all sites monitored and included in this report in
eastern New York were in the excessive range during June. A storm June 26-29 caused severe
flooding and damages and president Bush declared 8 counties eligible for federal disaster
assistance. Those counties eligible in eastern New York are Delaware, Herkimer, Montgomery,
Sullivan, and Ulster. Assessments are continuing in other areas as well. Ten sites exceeded
their 100-year flood discharge from this late June storm: Beaver Kill at Cooks Falls, West
Branch Delaware River at Walton, and 8 sites not included in this report, West Canada Creek
at Kast Bridge, Mohawk River near Little Falls, East Branch Delaware River at Fishs Eddy,
West Branch Delaware River at Stilesville and at Hale Eddy, Delaware River at Callicoon and
above Lackawaxen River near Barryville and at Port Jervis. New York city reservoirs were
full or near full just prior to the storm. The highest provisional period-of-record maximum
monthly mean discharge for June was recorded at 9 sites included in this report: Sacandaga
River near Hope (95 years), Canajoharie Creek near Canajoharie (13 years), Schoharie Creek
at Prattsville (104 years), Mohawk River at Cohoes (89 years), East Branch Delaware River
at Margaretville (69 years), Beaver Kill at Cooks Falls (93 years), West Branch Delaware
River at Walton (56 years), Oquaga Creek at Deposit (36 years), and Independence River at
Donnattsburg (64 years).
The total New York City reservoir system was at 102.8 percent of capacity on June 30;
normal for this period is 96.3 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 deficient range during June. Streamflow at
Susquehanna River at Conklin, Unadilla River at Rockdale, Chenango River near Chenango
Forks, Chemung River at Chemung, Genesee River at Wellsville, Fall Creek near Ithaca, and
Oneida Creek at Oneida were in the excessive range for the month. Four sites exceeded their
100-year flood discharge from the June 26-29 storm: Susquehanna River at Conklin, and 3 sites
not included in this report, Susquehanna River at Unadilla, and Chenango River at Sherburne
and at Greene. The highest provisional period-of-record maximum monthly mean discharge for
June was recorded at 2 sites included in this report: Unadilla River at Rockdale (70 years)
and Susquehanna River at Conklin (94 years). Streamflow at Allegheny River at Salamanca,
Tonawanda Creek at Batavia, Oatka Creek at Garbutt, and Flint Creek at Phelps were in the
normal range for the month. Streamflow at Cattaraugus Creek at Gowanda continued to be in
the deficient range for the third consecutive month.
Coram--Summary Report
Mean flow at Connetquot Brook near Central Islip was in the normal range for the fourth
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.

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.
