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.
