WATER RESOURCES REVIEW AND CURRENT CONDITIONS STATEMENT
FOR AUGUST 2001
Prepared September 6, 2001
Troy Subdistrict--Summary Report
Provisional streamflow conditions at sites monitored and included in this report in
eastern New York were in the normal to deficient range. Below normal precipitation and
above normal temperatures for August attributed to these conditions. The percent of
median flow decreased from July to August at all these sites with the largest change
occurring at Hudson River at Hadley (158% to 57%).
Ithaca Subdistrict--Summary Report
Provisional streamflow conditions at sites monitored and included in this report
for western New York were in the deficient range throughout the western part of the
state except for Chenango River near Chenango Forks and Unadilla River at Rockdale,
both stations located in the Upper Susquehanna River basin, which remained in the
normal range. The Allegheny River at Salamanca continued in the deficient range for
the fourth consecutive month. The second lowest monthly mean discharge for August was
recorded at Cattaraugus Creek at Gowanda, which remained deficient for the second con-
secutive month. Chemung River at Chemung, Genesee River at Wellsville, and Oatka Creek
at Garbutt were also all deficient for the second consecutive month. Tonawanda Creek
at Batavia and Fall Creek near Ithaca both decreased from normal during July into the
deficient range for August.
Coram Subdistrict--Summary Report
Mean flow at Connetquot Brook near Central Islip was in the deficient range after
three consecutive months in the normal range.

Provisional Data for August 2001
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 N1259, N1616, Q1249, Sa-1100, S1806, and S1810 have been affected by changes
in ground-water withdrawals or sewering.
