Digital data sets that describe aquifer characteristics of the Antlers aquifer in southeastern Oklahoma

Metadata Updated: November 12, 2020

This data set consists of digitized aquifer boundaries of the Antlers aquifer in southeastern Oklahoma. The Early Cretaceous-age Antlers Sandstone is an important source of water in an area that underlies about 4,400-square miles of all or part of Atoka, Bryan, Carter, Choctaw, Johnston, Love, Marshall, McCurtain, and Pushmataha Counties. The Antlers aquifer consists of sand, clay, conglomerate, and limestone in the outcrop area. The upper part of the Antlers aquifer consists of beds of sand, poorly cemented sandstone, sandy shale, silt, and clay. The Antlers aquifer is unconfined where it outcrops in about an 1,800-square-mile area. The data set includes the outcrop area of the Antlers Sandstone in Oklahoma and areas where the Antlers is overlain by alluvial and terrace deposits and a few small thin outcrops of the Goodland Limestone. Most of the aquifer boundary lines were extracted from published digital geology data sets. Some of the lines were interpolated in areas where the Antlers aquifer is overlain by alluvial and terrace deposits near streams and rivers. The interpolated lines are very similar to the aquifer boundaries published in a ground-water modeling report for the Antlers aquifer. The maps from which this data set was derived were scanned or digitized from maps published at a scale of 1:250,000.

Access Constraints Use Constraints: Most of the lines representing aquifer boundaries in this data set were extracted from digital geology data sets by Cederstrand (1996a, 1996b) based on a scale of 1:250,000. Some of the lines were interpolated where the Antlers aquifer is overlain by alluvial and terrace deposits near streams and rivers and are similar to the aquifer boundaries on maps in Morton (1992). Aquifer boundaries represented at this scale are indicative of broad, regional trends and should not be interpreted as site specific., Access Constraints: None
