Name: 2016 Aquifer Study Area (North Fork Red River)
Display Field: Id
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: The 2016 USGS aquifer boundary was modified from a 2015 OWRB aquifer study area. The boundary spans multiple counties, including Beckham, Greer, Jackson, Kiowa, and Roger Mills. The aquifer area is about 777 square miles (497,582 acres). The aquifer is defined as a major alluvial aquifer.

Name: Elevation of the Base of the Aquifer (ft) (North Fork Red River)
Display Field: ID
Type: Feature Layer
Geometry Type: esriGeometryPolyline
Description: The base of the North Fork of the Red River was modified from "Evaluation of aquifer performance and water supply capabilities of alluvial and terrace deposits of the North Fork of the Red River in Beckham, Greer, Kiowa, and Jackson Counties, Oklahoma (Douglas C. Kent, Department of Geology at Oklahoma State University, 1980)," with supplemental data provided by the OWRB in the form of drillers completion logs and lithologic log descriptions.

Copyright Text: The base contour map for the North Fork of the Red River aquifer was created for the 2017 USGS publication "Hydrogeology and simulated groundwater flow and availability in the North Fork Red River aquifer, southwest Oklahoma, 1980-2012," but was not shown in the publication.

Name: Potentiometric Surface Contour (ft), 2013 (North Fork Red River)
Display Field: OBJECTID

Name: Potentiometric Surface Contour (ft), 1980 (North Fork Red River)
Display Field: INDEX
Type: Feature Layer
Geometry Type: esriGeometryPolyline
Description: The full 1979 potentiometric surface contour map was derived from three figures (Figures 17,19, and 20) from the original 1980 publication. The contour map was created using drillers log data from the OWRB by subtracting depth to water from a surface elevation map created by the USGS. Areas where drillers logs were not available were filled in using refraction seismograph recorder data.
