Great Falls Lake
A 22-mile Caney Fork reservoir on the Cumberland Plateau, genuinely unlike any other TVA lake in Tennessee: the only TVA dam outside the Tennessee River watershed, feeding a world-renowned whitewater gorge, with a water level that moves more dramatically and less predictably than almost any other reservoir covered on this site.

Great Falls Dam impounds the Caney Fork River roughly 75 miles southeast of Nashville, straddling the line between White and Warren counties, with the reservoir itself also touching Van Buren County upstream. The dam was originally built in 1916 by the Tennessee Electric Power Company, making it one of the oldest hydroelectric projects in the region, and TVA purchased it in 1939 as one of seven dams acquired from private power companies during the agency's early years. Great Falls holds a genuinely unique distinction among TVA dams: it is the only one located outside the Tennessee River watershed entirely, sitting on a tributary system that eventually feeds into the Tennessee River much further downstream via Center Hill Lake.
The reservoir stretches roughly 22 miles along the Caney Fork and another 10 miles up the Collins River, with a small stretch of the lower Rocky River included as well, giving Great Falls a genuinely braided, multi-river character distinct from a single-channel reservoir. Unlike Cheatham Lake or Melton Hill Lake, both covered elsewhere on this site, which maintain remarkably stable pools year-round, Great Falls Lake experiences real, sometimes severe, water level fluctuations tied directly to spring rainfall on the Cumberland Plateau, a defining characteristic that shapes nearly everything about buying and living here.
What Buyers Need to Know First
The single most important fact about Great Falls Lake, more than anything else covered on this site's other topic pages, is that water level here is genuinely unpredictable in a way that Cheatham and Melton Hill Lakes simply are not. Heavy spring rains on the Cumberland Plateau can push the reservoir well above its normal operating range in a matter of hours, and TVA actively manages a substantial flood-storage capacity here specifically because of this volatility. Buyers used to the stable pools of Nashville-adjacent TVA reservoirs should recalibrate their expectations significantly before purchasing on Great Falls Lake.
