increased from May to June at all these sites. The excessive conditions were reported
at sites located in the mid to northern part of eastern New York.

Provisional streamflow conditions at sites monitored and included in this report
for western New York were in the normal range throughout the western part of the state
except for Chenango River near Chenango Forks, which increased from the deficient range

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.
