ABSTRACT

This set of maps and geohydrologic sections depict the geology and hydrology of valley­fill aquifers in

the 14­mile reach of the Chenango River valley between the Village of Greene and the area south of

Chenango Valley State Park, N.Y. This map report depicts the aquifers; locations of domestic,

production, and test wells; surficial geology; water­table altitude; potentiometric­surface altitude;

generalized saturated thickness of the unconfined (water­table) aquifer; generalized thickness of the

confined aquifer; and includes three geohydrologic sections.

The valley fill in the Chenango River valley consists primarily of (1) glaciofluvial deposits comprised of

stratified coarse­grained sediment (sand and gravel) that were deposited by meltwater streams flowing

on, below, and in front of the glacier; (2) lacustrine sediments consisting of stratified fine­grained

sediment (very fine sand, silt, and clay) that were deposited in proglacial lakes that formed at the front of

a glacier; and (3) recent alluvium consisting of alluvial fan deposits (sand, silt, and gravel), floodplain

sediments (fine­to­medium sand and silt), and channel deposits (sand and gravel).

The Chenango River valley contains an unconfined valley­fill aquifer throughout much of the study area,

and a confined valley­fill aquifer in the area between the northern edge of the Chenango Valley State

Park and the Village of Greene. The unconfined aquifer consists predominantly of alluvial and outwash

sand and gravel. The water table was mapped using water­level measurements obtained from wells

completed in the unconfined aquifer, and from altitudes of lakes, ponds, and streams as indicated on U.S.

Geological Survey 1:24,000­scale topographic maps. The depth to the water table typically ranges from 5

to 15 feet below land surface, but can locally be as much as 100 feet, such as in the ice­contact deposits

in the Chenango Valley State Park.

The confined aquifer is widely used by people living and working in the Chenango River valley. The

confined aquifer consists of ice­contact sand and gravel, typically overlies bedrock, and underlies a

confining unit consisting of lacustrine fine sand, silt, and clay. The confining unit is typically more than

100 feet thick in the central parts of the valley between Greene Landing Field and along the northern

edge of the Chenango Valley State Park. The thickness of the confined aquifer is more than 40 feet near

the Greene Landing Field.
