Location
Great Falls Dam is located approximately 94 miles (151 km) above the mouth of the Caney Fork, immediately downstream from the Caney Fork's confluence with the Collins River. The confluence of these two rivers (the Collins flowing from the southwest and the Caney Fork from the east) creates a peninsula. The two rivers nearly meet at the Narrows a "land bridge" connecting the peninsula to the mainland. Two tunnels deliver water from the Collins River section of the Great Falls Reservoir to the dam's Power House located on the Caney Fork 0.75 miles (1.21 km) downstream from the dam.
Great Falls Reservoir stretches behind the dam for 22 miles (35 km) along the Caney Fork and for roughly 10 miles (16 km) along the lower Collins River. The lake also includes a small stretch of the lower Rocky River, which empties into the Caney Fork about a mile east of the dam.
