This species is represented by 517 records from 23 sources: 390 museum (), 0 literature (), 0 research (), and 62 observation (), with 65 additional Trauth et al. (2004) locality points remaining unsourced (). It has been museum vouchered for 36 of 75 counties (), with 23 additional counties having other forms of reported occurrence (). Years of collection range from 1855 to present.

This species may occur statewide, outside of high gradient streams of the Interior Highlands. The Graptemys ouachitensis / pseudogeographica complex has historically presented taxonomic challenges and the occasional Arkansas specimen has proven difficult to determine specific assignment. Many localities plotted by Trauth et al. (2004), particularly along the western Arkansas Valley, remain unsourced. An isolated record from a city lake in northwest Arkanasas is currently attributed as a likely transplant. Powell et al. (2016) show a large intergrade zone with the G. p. pseudogeographica subspecies () across the northeast corner of the state.
