Nickajack Lake
10,370 acres on the Tennessee River, 25 miles northeast of Chattanooga. TVA's 6th main-stem reservoir sits at a stable 633.5-foot pool year-round — no drawdown, no winter mudflats, full dock access every month. The lake runs 46 miles through the Tennessee River Gorge, past Nickajack Cave and 100,000 endangered gray bats, connecting two states. Hamilton County taxes dropped to a historic low after the 2025 reappraisal.

Nickajack Lake occupies the 46-mile stretch of the Tennessee River between Nickajack Dam at river mile 424.7 and Chickamauga Dam on the edge of Chattanooga. TVA built Nickajack Dam between 1964 and 1967 to replace the aging Hales Bar Dam — a private utility structure that had been leaking from its foundation since 1913. The replacement dam cost $73 million and was completed December 14, 1967. TVA shut down Hales Bar operations the following day and by September 1968 had dismantled it entirely, merging the old Hales Bar reservoir into the new Nickajack Lake.
The lake is named for the Cherokee village of Nickajack, which once stood just upstream from the dam — now submerged beneath the reservoir. Nearby Nickajack Cave takes its name from the same Cherokee source and is now one of the most significant bat habitats in the Southeast. Hamilton and Marion counties divide the Tennessee shoreline, with the Marion County side backing into the Tennessee River Gorge — the rugged topographic feature TVA literature calls the "Grand Canyon of Tennessee."
What Buyers Need to Know First
The defining characteristic of Nickajack Lake for property owners is the pool stability. Unlike tributary reservoirs like Norris (25-ft drawdown), Douglas (up to 44 ft), or even J. Percy Priest (7 ft), Nickajack is a run-of-river reservoir. TVA operates it to maintain a stable 633.5-foot surface elevation year-round. The lake's primary purpose is navigation — its 600-by-110-foot lock lifts and lowers commercial barges 41 feet between Guntersville Lake downstream and Nickajack Lake to support the commercial barge channel of the Tennessee River. Navigation requires stable water. So Nickajack stays full.
What this means for a dock owner: your dock sits at the same water level in January that it does in July. You do not design for drawdown. You do not photograph mudflats in winter. You do not manage a gangway that pitches 25 degrees in October. The dock you install is the dock you use all year. For buyers who have been burned by dramatic drawdowns on other Tennessee lakes, Nickajack represents the most operationally stable pool in the state's major lake markets.
