Lake Sinclair Drawdown: Shoreline Work at Low Water

A lake that normally stays full

Lake Sinclair is kept close to full. Visit Milledgeville puts it simply: "The lake level is always full!" Its explanation is that Georgia Power generates electricity by pumping water between Lake Oconee and Lake Sinclair, and since Sinclair is downstream, it has to be at full pool to reach the pumps. The same page notes that the level is still "dictated by inflows," so heavy rain can push it up.

For shoreline owners, that steadiness cuts both ways. Docks and walls aren't routinely left out of the water, but the base of a seawall, the bottom edge of a riprap slope, and the lower part of dock pilings stay underwater nearly all the time.

The homeowner maintenance drawdowns

Georgia Power does lower the lake on purpose from time to time. The Milledgeville Messenger reported that Georgia Power lowers the water level of Lake Sinclair "every five years" so property owners can "repair, replace, or upgrade shoreline structures" that are normally underwater or hard to reach. The two most recent:

The 2020 notice also warned that heavy rain could push the lake above the planned range, so a drawdown's depth isn't guaranteed day to day.

When is the next one?

Georgia Power hasn't published the date of the next Lake Sinclair drawdown that we could find, and we won't guess at one. If you're planning work that depends on low water, ask the East Georgia (Oconee/Sinclair) Resources Office in Eatonton, 706-484-7500, and watch for Georgia Power's notice and the county advisories that pass it along.

What low water is good for

With the lake down about five feet, more of the shoreline is in the open. That makes it a practical time to:

• Look at the base of an existing seawall for gaps, undermining or soil loss.
• Check whether old riprap has slid down or out from the bank.
• Inspect dock pilings and boathouse posts below the usual waterline.
• See how much of the bank below the waterline has been cut away, which matters for Georgia Power's "evident cut bank erosion" test.
• Take photos for a permit application or a contractor's quote while everything is visible.

Even if no work happens during the drawdown, those photos and measurements make the next conversation with Georgia Power or a contractor much easier.

What low water doesn't change

A lower lake doesn't loosen the rules. Baldwin County Fire Rescue's 2025 advisory, passing along Georgia Power's message, reminded owners to get the required permits before shoreline work, including ground disturbance and maintenance to "seawalls, docks, and boathouses." Everything on the permits page still applies:

• Georgia Power's written approval before any shoreline abutment or seawall work.
• A turbidity barrier in place before an existing seawall comes out.
• Riprap on the lake side of any new or replacement seawall.
• No mechanical clearing in the 25-foot vegetative buffer without Georgia Power's prior written approval.
• No man-made beaches, and no sand added to a natural beach, even where the exposed bottom looks sandy.
• Dredging only under a Georgia Power permit, up to 500 cubic yards per property, with a certified survey above 400 cubic yards.

Getting ready before the water drops

1. Start the permit early. Georgia Power doesn't publish a processing time, and a new seawall also needs county and state permits as they apply.
2. Talk to a contractor early. A drawdown is a short window, and everyone on the lake has the same one.
3. Photograph your shoreline at full pool now, so you can compare it with what the low water shows.
4. Check with your county if the work involves a new wall or ground disturbance. The permits guide lists Putnam, Baldwin and Hancock offices.

Boats and lifts during a drawdown

The 2025 advisory asked boat owners to secure all boats and personal watercraft and to take out any vessel meant for trailering before the water fell. If your boat sits on a lift, ask your lift installer whether anything should be adjusted for the lower water. Boat lifts covers the Georgia Power lift rules.

Drawdown questions

How far does Lake Sinclair drop in a drawdown?

In 2020 the target was 335 feet above mean sea level, five feet below full pool. For 2025, the Milledgeville Messenger reported a drop of about five feet by November 2, weather permitting.

How often does Georgia Power lower the lake?

The Milledgeville Messenger described the homeowner drawdown as happening every five years. The two most recent began in October 2020 and October 2025. Georgia Power hasn't announced the next date that we could find.

Do I need a permit to repair my seawall during a drawdown?

Yes. Georgia Power's FAQ says maintenance of any shoreline structure, seawalls included, needs a construction permit, and its drawdown reminder in 2025 said the same. The permit is free.

Can I add sand to the exposed shoreline?

No. Georgia Power's guideline says man-made beaches are not allowed and no sand may be added to an existing natural beach.
