The legend associated with Mule Jail Lake varies from family to family, but in general, Mule Jail Lake received its name from the one-time island that is central to the oxbow lake. During the American Civil War, as the Union army moved through the Jackson area, farmers gathered as many of their livestock as possible and moved them to this island and cut all access to the island. Thus many animals were spared possible slaughter.
