The clearest lake in South Carolina sits above a flooded valley most people don’t know exists

The wild secret of Lake Jocassee

About 40 miles northwest of Greenville, tucked into the Blue Ridge Mountains, sits a lake most Americans have never heard of.

Lake Jocassee covers 7,500 acres, reaches 300 feet deep, and holds water so clear you can see 15 feet down from the surface on a calm day.

National Geographic put the surrounding Jocassee Gorges on its list of 50 last great places on Earth. Below the surface, an entire valley waits.

The Cherokee valley that now sleeps underwater

The name Jocassee comes from a Cherokee legend and means “Place of the Lost One.” That name hits differently when you learn what happened here.

In 1973, Duke Power dammed the valley to generate hydroelectric power, and the Jocassee Valley, once Cherokee homeland, went under. Four rivers still feed the lake: the Whitewater, Thompson, Horsepasture, and Toxaway.

That cold mountain water keeps the lake unusually clear, and the valley it buried never fully disappeared.

43,000 acres of wilderness with its own rainforest

The lake sits inside the Jocassee Gorges, a protected stretch of wilderness covering about 43,000 acres.

The gorges pull in 75 to 80 inches of rain per year, enough to create the only temperate rainforest east of the Rockies.

The Eastern Continental Divide runs straight through here, and the combination of water, elevation, and geography supports more than 60 species of rare plants.

The National Audubon Society named it an Important Bird Area, and the biodiversity backs that up.

Waterfalls that you can only reach by boat

Most of the waterfalls around Lake Jocassee have no trail leading to them. The only way in is by water.

Laurel Fork Falls drops 80 feet in three sections down a wooded slope and empties into the lake. At high water, Wright Creek Falls plunges straight into the lake, and when the water drops, you can walk behind it.

Mill Creek Falls cascades over sheer rock close enough that you can pull a boat up and feel the spray. Guided waterfall tours run all year, and some falls only show themselves in winter when the leaves come down.

Paddle 75 miles of shoreline with almost no one around

Fewer than 40 private homes sit on the entire lake. That leaves 75 miles of mostly undeveloped shoreline for paddlers to work through.

Kayakers and canoeists find coves and inlets that see almost no boat traffic.

The upper reaches of the lake stay free of motorized personal watercraft, so the water stays calm and the only sounds are the kind you came for.

Rentals for kayaks, canoes, and paddleboards run seasonally out of Devils Fork State Park, and guided kayak tours go out regularly.

A wildflower so rare 90 percent of it grows right here

The Oconee Bell blooms for two to three weeks every spring, from mid-March into early April, and the Jocassee Gorges hold about 90 percent of the world’s entire population of the flower.

The Cherokee called it “Shee-Show,” meaning “two-colored plants of the gods,” and treated it as a rain talisman. Devils Fork State Park has a one-mile nature trail where you can walk through colonies of them in bloom.

If your timing is off by a few weeks, you’ll miss it entirely, so plan the trip around the window.

Scuba dive a sunken lodge, a girls camp, and a forest

When the valley flooded in 1973, the old community went down with it. Scuba divers have been exploring what’s left ever since.

About 60 feet down sits a Chinese junk boat you can swim through.

Deeper in the lake, the ruins of an old lodge and a former summer camp for girls rest on the bottom. Headstones from a church cemetery that got relocated sit in the silt.

Below 100 feet, standing forests remain intact on the lake floor.

On a clear day, visibility can stretch 50 feet, and this ranks as one of the top freshwater dive sites on the East Coast.

Brown trout, rainbow trout, and state fishing records

The same cold, clean water that makes Jocassee good for diving makes it good for fish.

Brown trout, rainbow trout, and smallmouth bass all thrive here, and the lake has produced multiple South Carolina state fishing records.

Water temperatures run about 45 degrees in winter and top out around 78 degrees in summer, which keeps the fish active through the season. You’ll need a South Carolina fishing license before you cast a line.

Bald eagles, black bears, and the salamander capital of Earth

Bald eagles and peregrine falcons move through the sky above the lake. Black bears, bobcats, and wild turkeys roam the gorges below the ridgeline.

In winter, common loons settle on the water, and their calls carry across the lake in the early morning.

The Southern Appalachian Mountains hold more salamander species than anywhere else on Earth, and the Jocassee Gorges sit at the center of that.

The undeveloped shoreline gives all of it room to exist without much interference.

Devil’s Fork State Park puts you right on the water

The park takes up 622 acres along the lake’s southern shore and gives you more options than most state parks.

You can tent camp at one of 59 sites with water and electric hookups, or rent one of 20 lakeside villas that come with full kitchens, screened porches, granite countertops, and flat-screen TVs.

Twenty-five boat-in backcountry campsites sit accessible only by water. Four boat ramps, picnic areas, and a camp store round out what’s available.

Day use runs $8 for adults, $5 for South Carolina seniors, and $4 for kids ages 6 to 15.

A few things to sort out before the drive

No restaurant sits close enough to the lake to be useful, so bring your food and drinks with you. The park has 173 day-use parking spots and turns people away when those fill, which happens fast on summer weekends.

Get there early. Campsite and villa reservations open 13 months out through the South Carolina State Parks system, and the good spots go quickly. Swimming is allowed but there are no lifeguards.

Mountain lake temperatures run cooler than you’d expect, so pack a layer even in summer.

Why this lake stays in your mind

Protected land wraps nearly every shore of Lake Jocassee, which is the main reason it still looks the way it does. The water stays clear, the forest stays intact, and the wildlife stays.

The Cherokee revered this valley for centuries before the dam changed it, and something about the place still carries that weight.

Whether you come for the waterfalls, the diving, the paddling, or the wildflowers, the lake gives you more than one reason to stay longer than you planned.

Visit Devil’s Fork State Park in Salem, South Carolina

You get to Lake Jocassee through Devils Fork State Park, the only public access point on the water.

The park sits off SC Highway 11, the Cherokee Foothills National Scenic Highway, about 40 miles northwest of Greenville. It’s open year-round.

If you have time, Jumping Off Rock nearby puts you above the lake and gorges with a wide view.

Sassafras Mountain, South Carolina’s highest point at 3,553 feet, is also close and looks out over three states on a clear day.
