ADA Accessibility Notes

No ADA accessibility available at Great Falls Dam and Reservoir

Great Falls is one of seven dams acquired by TVA from private companies, and it’s the only TVA dam located outside the Tennessee River Valley. It was completed in 1916 by the Tennessee Electric Power Company and was bought by TVA in 1939 and is located about 75 miles southeast of Nashville on the Caney Fork River. It’s named for the impressive falls that plunge into the Caney Fork a short distance below the dam.

The area surrounding Great Falls Reservoir is a scenic wilderness with numerous waterfalls, including the one that gives the reservoir its name. Whitewater rapids below the dam are world-renowned for kayaking and canoeing and have been the site for national and international paddling events.

Nearby Rock Island State Park offers hiking, camping and swimming. There is a boat ramp above the dam on Great Falls Reservoir, an old mill site on the river below the dam and spectacular fishing in the scenic gorge of the Caney Fork River.

Note: swimming or wading is not permitted downstream of the Powerhouse at any time, regardless of water releases. Always use caution in the gorge; water may rise rapidly. Monitor your surroundings and watch for slick rocks and swift currents.
