About Watts Bar Lake
Watts Bar Lake is a reservoir on the Tennessee River in Tennessee, operated by Tennessee Valley Authority. Its full summer pool sits at 741 ft above sea level. Live water levels come from the Tennessee Valley Authority (TVA) and update hourly.
Understanding Watts Bar Lake's water level
"Full pool" is the elevation Tennessee Valley Authority targets when Watts Bar Lake is completely filled — 741 feet above sea level. TVA runs Watts Bar Lake as a mainstem navigation-and-power lake, holding it in a narrow band close to 741 ft for most of the year with only a modest winter dip, so even small changes are noticeable here.
Because it's run for navigation and power, Watts Bar Lake stays fairly flat year-round — easing down a little over winter and returning to its summer level by spring. The sharpest short-term moves come from heavy rain upstream or generation changes at the dam.
The recent high and low above are drawn from the published history available for Watts Bar Lake, so they show how today compares over that record rather than an all-time extreme. The 12-month and 5-year chart views make the trend and the lake's usual seasonal shape easy to see.
