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

This data set consists of digitized polygons of a constant
recharge value for 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 recharge data set was created from digital data sets
developed to produce a map for a previously published
report. Most of the recharge to the Central Oklahoma aquifer
is infiltration of precipitation through outcrops of the
Garber Sandstone and Wellington Formations, the Chase,
Council Grove, and Admire Groups, and the alluvial and
terrace deposits. The median recharge to the aquifer is 1.61
inches per year.
