Rock Island is a sleepy southern town located in middle TN. It is currently home to a lovely state park by the same name as the town. This state park (est. 1969) consists of a dam operated by the Tennessee Valley Authority, and as one might imagine, the park boasts some epic waterfalls including Great Falls, and Twin Falls which reside below the TVA dam on the Caney Fork. It is also home to a few historic structures including the spring house and the great falls cotton mill, the latter of which cannot be entered by the public. The town has a history speckled by entrepreneurs from the post civil war era up to the the 1920s, hoping to harness the power of the water there, whose businesses were ultimately defeated by flash flooding. After the industry dried up, so did the population of the town. The area now attracts vacationers for fishing and other water related recreational opportunities.
