Johnsonville State Historic Park in Tennessee preserves the intertwined history of the 1864 Battle of Johnsonville and the town of Johnsonville, which occupied the site from 1864 to 1944. Its significance lies in recalling both a Civil War landscape and a community later lost when the Tennessee Valley Authority created Kentucky Lake and inundated the town. The park thus represents a place shaped first by conflict and settlement, then by major twentieth-century changes to the Tennessee River. Today it also serves for outdoor recreation, with hiking trails, birding in wooded and waterfront areas, and fishing on Kentucky Lake.
