September 12, 1938
The town of Oak Grove (Carroll County) was incorporated. The town is one of twelve communities in Arkansas identified as Oak Grove, and the only one to be incorporated. In 1983, historians wrote that Oak Grove continues to support a small population with a few stores and a post office. The quiet living in the community finds its focus around the churches of the community and the softball activities of the summer months. The town has since grown further, supporting a city hall, a fire station, a convenience store, shops, and churches.
