Digital data sets that describe aquifer characteristics of the alluvial and terrace deposits along the North Canadian River from Oklahoma City to Eufaula Lake in east-central Oklahoma

This data set consists of digital aquifer boundaries for the
alluvial and terrace deposits along the North Canadian River
from Oklahoma City to Eufaula Lake in east-central Oklahoma.
Ground water in 710 square miles of Quaternary alluvial and
terrace deposits along the North Canadian River is an important
source of water for irrigation, industrial, municipal, stock,
and domestic supplies. The aquifer, composed of alluvial and
terrace deposits, consists of sand, silt, clay, and gravel. The
aquifer is underlain and in hydraulic connection with the upper
zone of the Permian-age Garber-Wellington aquifer and the
Pennsylvanian-age Ada-Vamoosa aquifer.

The aquifer boundaries were digitized from a published
ground-water modeling report and some lines were extracted from
published digital geology data sets.
