Digital data sets that describe aquifer characteristics of the Central Oklahoma aquifer in central Oklahoma

This data set consists of digitized aquifer boundaries created
for a previously published report about the Central Oklahoma
aquifer in central Oklahoma. This area encompasses all or part
of Cleveland, Lincoln, Logan, Oklahoma, Payne, and Pottawatomie
Counties. The Central Oklahoma aquifer includes the alluvial
and terrace deposits along major streams, the Garber Sandstone
and Wellington Formations, and the Chase, Council Grove, and
Admire Groups.

The Quaternary-age alluvial and terrace deposits consist of
unconsolidated clay, silt, sand, and gravel. The Permian-age
Garber Sandstone and Wellington Formations consist of sandstone
with interbedded siltstone and mudstone. The Permian-age Chase,
Council Grove, and Admire Groups consist of sandstone, shale,
and thin limestone.

The Central Oklahoma aquifer underlies about 3,000 square miles
of central Oklahoma where the aquifer is used extensively for
municipal, industrial, commercial, and domestic water supplies.
Most of the usable ground water within the aquifer is from the
Garber Sandstone and Wellington Formations. Substantial
quantities of usable ground water also are present in the
Chase, Council Grove, and Admire Groups, and in alluvial and
terrace deposits associated with the major streams.
