Digital data sets that describe aquifer characteristics of the Enid isolated terrace aquifer in northwestern Oklahoma
This data set consists of digitized polygons of constant
hydraulic conductivity values for the Enid isolated terrace
aquifer in northwestern Oklahoma. The Enid isolated terrace
aquifer covers approximately 82 square miles and supplies water
for irrigation, domestic, municipal, and industrial use for the
City of Enid and western Garfield County. The Quaternary-age
Enid isolated terrace aquifer is composed of terrace deposits
that consist of discontinuous layers of clay, sandy clay, sand,
and gravel. The aquifer is unconfined and is bounded by the
underlying Permian-age Hennessey Group on the east and the Cedar
Hills Sandstone Formation of the Permian-age El Reno Group on
the west. Cedar Hills Sandstone Formation fills a channel
beneath the thickest section of the Enid isolated terrace
aquifer in the midwestern part of the aquifer.
The hydraulic conductivity polygons from a ground-water modeling
thesis and report were transferred to a map and digitized. The
map digitized was published at a scale of 1:62,500. Hydraulic
conductivities reported in the ground-water modeling thesis and
report for the Enid isolated terrace aquifer are 93.6 feet per
day and 134 feet per day.
Ground-water flow models are numerical representations that
simplify and aggregate natural systems. Models are not
unique; different combinations of aquifer characteristics may
produce similar results. Therefore, values of hydraulic
conductivity used in the model and presented in this data set
are not precise, but are within a reasonable range when
compared to independently collected data.
