Is There a Town Under Lake Sam Rayburn?

Yes. There is a ghost town under the lake. A town named Zana sat on the Angelina River in the late 1800s. It was a thriving community with a cotton gin, grist mill, and even river steamboats. The town was granted a post office, and by 1896 50 people called it home. However, by the 1930s only a few community members remained, and the town was dropped off the maps. When the reservoir was constructed, Zana became a statistic and one of the many submerged ghost towns in the state’s history.

The reservoir destroyed all evidence of the quaint sawmill town, Zana.
