Clarks Hill Lake, Georgia

The Lake at a Glance

Clarks Hill Lake is one of the most underrated relocation destinations in the Southeast — and one of the most misunderstood. At 71,100 acres with 1,200 miles of shoreline, it ranks as the third-largest man-made lake east of the Mississippi River, behind only Kentucky Lake and Lake Marion. Built by the U.S. Army Corps of Engineers between 1946 and 1954 at a cost of $79 million, the lake straddles the Georgia-South Carolina state line along the Savannah River — giving buyers two distinct markets to compare, with different tax structures, different agent pools, and different legal frameworks on either side of the water.

On the Georgia side, the lake is officially called Clarks Hill Lake — a name enshrined by the Georgia legislature in 1989 after federal legislation renamed the project after Senator Strom Thurmond in 1987. The federal name is J. Strom Thurmond Lake. The South Carolina side commonly uses "Lake Thurmond." If you have talked to agents, scanned listings, or searched for information about this lake and gotten confused, it is because all three names refer to the same body of water. That name confusion has real consequences for buyers — your agent may not be licensed in both states, listings may appear under different lake names depending on which side of the state line they sit on, and closings follow different legal conventions in Georgia and South Carolina.

What Buyers Need to Know First

The single most important fact for any buyer approaching a lakefront property on Clarks Hill Lake is this: dock permits issued by the U.S. Army Corps of Engineers, Savannah District, are non-transferable. When the seller's permit expires or when the property changes hands, the new owner must apply for a fresh Shoreline Use Permit. That permit takes two to four weeks to process. The permit does not convey private property rights to the shoreline — you are permitting use of federal land, not owning it. Buyers who purchase a Clarks Hill lakefront property expecting to step into the seller's dock permit will be disappointed. Your real estate attorney should confirm the permit status of any structure on federal land before closing.

The second critical fact is the winter drawdown. The Army Corps manages the pool elevation for flood control and hydroelectric generation. Full pool is 330 feet above mean sea level. In winter, the lake typically drops 5 to 10 feet below full pool — in late November 2024, the lake was tracking at 322.98 feet, roughly seven feet below full pool. That drawdown exposes shoreline, can strand fixed docks, and can make some boat ramps unusable during winter months. Buyers looking at fixed dock structures need to understand minimum depth at winter draw-down, not just full pool depth at the time they visit in summer.

Two States, Two Markets, One Lake

The Georgia counties bordering Clarks Hill Lake are Lincoln, Columbia, McDuffie, and Wilkes. The South Carolina counties are McCormick and Edgefield. Columbia County, Georgia sits on the southern end closest to Augusta and carries the highest property values and lowest tax rates on the Georgia side — primarily because it is a fast-growing Augusta suburb with a diversified tax base. Lincoln County, directly on the lake's western shore in Georgia, is the primary lakefront county for GA-side buyers and carries rural millage rates that are typically higher than Columbia County on a percentage basis but lower in raw dollar terms due to lower assessed values.

South Carolina buyers encounter a different tax structure entirely — SC assesses owner-occupied property at 4% of fair market value versus Georgia's 40% of fair market value, which means the calculation looks dramatically different on paper even before applying millage rates. The SC retirement tax picture is also different from Georgia, and SC has its own closing conventions and title insurance practices that differ from what Georgia buyers may be used to. Buyers who are considering properties on both sides of the lake — or whose agent is only licensed on one side — need to understand that they are working with two completely separate regulatory and tax systems.
