Blue Ridge Dam safety study: what TVA has said (as of October 2026)

As of October 2026, TVA says Blue Ridge Dam is safe for normal operations and that its safety study is scheduled to be completed during calendar year 2026. TVA’s Blue Ridge Dam safety study page, last updated July 2, 2026, also says it has no active plans to change the seasonal levels of Lake Blue Ridge (TVA’s Blue Ridge Reservoir). Nothing about a fix, a drawdown or a new dam has been decided.

This page sticks to what TVA has published, dates each statement, and lists what to watch for next. We will update it with the new date when TVA changes its page.

The dam in brief

Blue Ridge Dam is an earthen dam on the Toccoa River in Fannin County, Georgia, near the Mineral Bluff community and about two miles northeast of the city of Blue Ridge, per a TVA siren notice. It is 175 feet high and 1,553 feet long, according to TVA’s plant page. The Toccoa Electric Power Company built it between 1925 and 1930, it went into service on July 1, 1931 (TVA history), and TVA bought it in 1939. TVA lists its benefits as flood control, recreation, water supply, environmental stewardship and low-cost, clean power. Our Blue Ridge Dam page covers visiting the overlook and the powerhouse picnic area.

Why TVA is studying it

As of its July 2026 update, TVA’s study page names two issues.

How the dam was built

The dam was built with a “semi-hydraulic filling” technique. TVA says the method introduces an inherent vulnerability into any dam built with it, and it is no longer used in modern dam construction. In TVA’s words, the dam “was built in a way that makes it vulnerable to a strong earthquake,” and in an extreme earthquake it “could develop significant cracks.”

The spillway slab

TVA says the concrete slab of the spillway has deteriorated over the years, and that long use of the spillway during an extreme flood could damage the chute. In the same breath, TVA rates the chance of a spillway failure causing an uncontrolled release as very low. Both halves of that statement matter, so we print them together.

What TVA has said, as of October 2026

Notice what the table does not contain. As of October 2026, TVA has not announced a drawdown, a new dam, a construction date or a cost. A page that gives you a drawdown schedule or a construction start is getting ahead of TVA.

Where the public process stands

TVA says it intends to issue a public notice of its intent to conduct a detailed, comprehensive study of several potential options to increase the safety of the dam and spillway, and to take public comment under NEPA. We searched the Federal Register on October 18, 2026, for “Blue Ridge Dam” and found no such notice yet. Until one appears, no alternatives, drawdown depths or schedules have been published for comment.

That notice is the step to watch. Under TVA’s stated plan, it is how the public part of the process begins.

TVA says it intends to issue a public notice for a detailed study of options and will seek public comment under the National Environmental Policy Act. A Federal Register search on 2026-10-18 found no such notice for Blue Ridge Dam yet. (TVA, checked Oct 18, 2026)

Has the lake been lowered for dam work before?

The most recent example we can document comes from a secondary source, so treat it as background only. Wikipedia reports that TVA began lowering the lake for a dam rehabilitation project in July 2010, with the drawdown portion of the work finished in April 2011. Wikipedia’s dam article, citing TVA’s 2009 environmental assessment, says that project repaired the penstock and stabilized the intake tower and dam faces so that severe drawdowns would no longer be needed. None of that tells you what the current study will recommend.

What it means right now

• Lake levels: as of October 2026, TVA says it has no active plans to change seasonal levels. TVA’s published guide curve still swings about 22 feet between summer and winter in a normal-rainfall year (TVA). Check TVA’s lake-level page before you launch, and see our lake levels guide for the curve month by month.
• Downstream: TVA names McCaysville, Mineral Bluff, Copperhill and Pleasant Hill among the communities below the dam. In March 2022 TVA placed dam-warning sirens in Tammen Park, in Mineral Bluff, on Toccoa River Forrest Road and in McCaysville, and it tests them every year (TVA). If you hear the sirens, feel a severe earthquake or see rapidly rising water, TVA’s instruction is to get off the river to high ground immediately. Our Toccoa River page covers the river below the dam.
• Buyers and owners: add TVA’s study page to your due diligence and note the date it was last updated. It is the only source for what TVA plans. Our Lake Blue Ridge homes page lists the other TVA checks, including 26a dock permits.

As of October 2026, TVA says it has no active plans to change the reservoir's seasonal levels, either temporarily or permanently, while the study is under way. (TVA, checked Oct 18, 2026)

What to watch for

• A new “last updated” date on TVA’s Blue Ridge Dam safety study page.
• TVA saying the study is complete. As of October 2026, it is scheduled for calendar year 2026.
• TVA’s public notice and the start of a NEPA comment period, most likely visible in the Federal Register.
• Any change to TVA’s statement that there are no active plans to alter seasonal levels.

Until TVA publishes one of those, treat anything else you hear about the dam’s future as unconfirmed.
