Is Watts Bar Lake full?
TVA runs Watts Bar Lake on a seasonal operating guide, higher in summer and lower in winter. We do not show a full-pool figure because TVA does not publish its targets in a form we can read automatically, so this page compares the level with past years instead. It is 0.09 ft lower than a year ago (739.82 ft on Nov 7, 2025).
