"Hartwell or Keowee?" is probably the question I get most from people moving to the Upstate. They're only a few miles apart, but they feel different, they're managed differently, and the rules for building on the shoreline aren't the same. Here's how I explain it.
The quick numbers
Lake Hartwell: About 56,000 acres of water and 962 miles of shoreline, according to SC DNR. It sits on the South Carolina and Georgia line on the Savannah River and touches Anderson, Oconee and Pickens counties.
Lake Keowee: About 18,500 acres, mostly in Oconee County with parts in Pickens County. It was created by Duke Energy in the early 1970s and is fed by Lake Jocassee upstream.
Hartwell is the big, sprawling lake with lots of public access. Keowee is smaller and known for its clear water and mountain views toward the Blue Ridge.
Who manages each lake (and why it matters)
This is the part buyers should care about most.
Lake Hartwell is owned and managed by the U.S. Army Corps of Engineers. The Corps owns land around the lake up to a government property line, and docks are governed by the Hartwell Shoreline Management Plan, which took effect in November 2020. Shoreline is allocated in categories, and the Corps has said it can't make site-specific allocation changes. Translation: if a lot isn't in an area allocated for private docks, wishing won't change it.
Lake Keowee is managed by Duke Energy under a federal FERC license. Docks and shoreline work need a Duke lake use permit, and Duke's Shoreline Management Plan classifies the shoreline. We covered Keowee docks in detail in our guide to Duke Energy permits.
Either way, the rule is the same: confirm dock eligibility for the specific lot before you buy.
Lifestyle differences
Hartwell is great if you want room to roam on a boat, lots of marinas and parks, and quick access to Clemson, Anderson and I-85. Clemson University sits right on the lake, so game-day boating is a real thing.
Keowee tends to attract buyers who want a quieter lake feel and mountain scenery, with Seneca, Salem and Six Mile close by. Many of the area's gated golf and lake communities are here.
Water levels
Both lakes are managed reservoirs, so levels can move with rainfall and operations. Before you buy, look at the water depth at the dock in late summer or fall, not just in spring when everything is full.
Price and inventory
Prices on both lakes range widely depending on the cove, depth, dock and view. I won't throw out averages here because they move every month and they hide the details that matter. Ask us for current sales on the exact stretch of water you like.
Our motto is "Be the kind of Realtor you'd want your Mother to have." When you're choosing between two lakes, that means telling you the downsides of each one too.
Frequently asked questions
Which lake is bigger?
Lake Hartwell, at about 56,000 acres, is roughly three times the size of Lake Keowee.
Can I get a dock on either lake?
Possibly, but it depends on the specific lot. Hartwell docks are governed by the Army Corps' Shoreline Management Plan, and Keowee docks by Duke Energy's.
Which lake is closer to Clemson?
Lake Hartwell borders Clemson. Lake Keowee is a short drive away near Seneca.
