Triennial Drawdown

Next Triennial Drawdown: October 2025

Every three years, Lake Harding undergoes a planned drawdown, which is a temporary lowering of water levels as part of Georgia Power’s lake management schedule. This event supports shoreline maintenance, environmental care, and community improvement projects.

What Is the Drawdown?

The triennial drawdown usually happens in the fall, most often in October or November, and reduces Lake Harding’s water level by approximately 4 to 5 feet below full pool. The lake remains at that lower level for several weeks before gradually returning to normal.

Why It Happens

The drawdown serves several important purposes:

• Shoreline Maintenance
  Property owners can inspect and repair docks, seawalls, boat lifts, and other structures while the lake is low.

• Environmental Management
  Lowering the lake exposes the lakebed, making it easier to manage vegetation, clean up debris, and reduce sediment buildup.

• Dam Operations
  Georgia Power uses this time to inspect hydroelectric facilities and perform any needed maintenance in compliance with federal regulations.

What to Expect

• Advance Notice
  Georgia Power announces the drawdown schedule ahead of time. This includes estimated start and end dates and the target water level.

• Gradual Drop
  The water level is lowered over several days and remains low for two to three weeks.

• Refill Process
  Refill begins after the drawdown period ends. The timing depends on rainfall and river conditions.

How to Prepare

If you own lakefront property, here are a few steps you can take:

• Schedule dock or seawall maintenance while the lake is low.

• Adjust boats, lines, and lifts to avoid damage.

• Make sure any repairs or new construction follow Georgia Power’s shoreline permitting requirements.

Community Involvement

Local groups such as the Lake Harding Association and the Chattahoochee River Conservancy often organize cleanup and restoration efforts during the drawdown. The event also ties into the popular Lake Harding Poker Run, which raises funds for lake improvements and beautification projects.
