The Ozark foothills of Oklahoma hide a lake with cliffs, ruins, and wild goats

Oklahoma’s wildest lake keeps its best secrets underwater

Most people picture Oklahoma as flat and dry. Lake Tenkiller will change that.

Tucked into the Ozark foothills of eastern Oklahoma, this 12,900-acre reservoir sits inside a landscape of rocky bluffs and wooded hills, with water that runs blue-green and clear.

It covers 130 miles of shoreline, drops more than 130 feet at its deepest point, and holds more surprises per acre than anything else in the state.

The Cherokee family who gave this lake its name

The U.S. Army Corps of Engineers built the earth-fill dam here between 1947 and 1952, backing up the Illinois River into what is now Lake Tenkiller.

The lake takes its name from a Cherokee family who owned the land and ran a ferry crossing on the river. Legend holds that the family’s Cherokee warrior ancestor earned the name from 10 notches on his bow.

When the dam went up, a small town called Cookson had to move. Some buildings couldn’t be relocated.

They’re still down there.

Sunken buses, helicopters, and a schoolhouse

Lake Tenkiller is one of Oklahoma’s top scuba diving spots, and the dive park at Fisherman’s Point in Tenkiller State Park is the reason.

Opened in 2004, the park holds a collection of deliberately sunken attractions: boats, a school bus, and a decommissioned U.S. Coast Guard helicopter.

That helicopter, aircraft number 1469, started its career in Brooklyn, New York, and was decommissioned in San Diego in 2007 before being sunk here.

On a busy summer weekend, 60 to 100 divers work this stretch of water.

Four-foot walls and an outlaw hideout fifty feet down

The history goes deeper than the helicopter. Divers can explore the Buckhorn School, a 1930s building constructed by the Works Progress Administration.

Its four-foot rock walls still stand underwater, and you can still spot the remains of the old outhouse nearby.

Fifty-eight feet below the surface, the Terrapin Creek Bridge connects the old towns of Cookson and Buckhorn.

Nearby, a structure called the Mob House rises 14 feet from the lake floor, a remnant of the area’s outlaw days during Prohibition.

Dive shops along the shore handle training, certification, and gear rental for every experience level.

Paddle half a mile to meet the goats of Pettit Bay

Here’s something you won’t find on most tourist maps: a small island in Pettit Bay where a handful of tame goats live. Nobody knows exactly how they got there.

A game ranger confirmed it. You reach the island by kayak or boat, about a half-mile paddle from Pettit Bay, and when you arrive, the goats come to you. They’re friendly and looking for treats.

Lake patrol officers and local fishermen have taken it upon themselves to keep watch over the animals and help keep them fed.

Cast a line for bass, crappie, walleye, or rainbow trout

The lake holds largemouth bass, spotted bass, white bass, crappie, catfish, and walleye, and it draws enough tournament anglers to host Bassmaster series events.

Below the dam, the lower Illinois River earns its own distinction.

It’s Oklahoma’s oldest designated trout stream, and the state stocks it with 100,000 rainbow trout each year along a 7.75-mile stretch from the dam to the town of Gore.

Gore leans into the title and calls itself the Trout Capital of Oklahoma.

Drift down the Illinois River from Tahlequah

Before the river reaches the lake, the upper Illinois River near Tahlequah runs through steep bluffs, swimming holes, and forested Ozark scenery that makes it one of Oklahoma’s most popular float trip destinations.

Outfitters put you on the water by raft, canoe, kayak, or tube, with route options ranging from four to 13 miles. The current runs gentle to moderate, which means families and first-timers do just fine.

The float season runs from spring through early fall, and on a warm weekend, the river gets busy.

Two state parks, 14 campgrounds, and a kids’ fishing pond

Tenkiller State Park covers 1,190 acres near the dam and comes with cabins, RV sites, tent camping, a swimming pool, hiking trails, a nature center, playgrounds, and picnic shelters.

Cherokee Landing State Park holds down the lake’s northern end with additional camping and boat access.

Back at Tenkiller State Park, kids 16 and under fish for free at a dedicated fishing pond, with a limit of three fish per day.

The park’s Pine Cove Marina handles boat rentals, fuel, and has a floating restaurant if you need a break from cooking over a camp stove.

Bald eagles patrol the shoreline from January through March

Each winter, bald eagles move in along Lake Tenkiller, drawn by the fish and the wooded shoreline. Tenkiller State Park’s Driftwood Nature Center runs free birdwatching events from January through March.

Nearby, the Sequoyah National Wildlife Refuge offers free guided eagle tours on Saturdays during the same window. The refuge played a real role in bringing southern bald eagles back from near-extinction caused by DDT.

Oklahoma had zero known bald eagle nests in 1984. Today the state counts more than 350 active nests.

Deer, otters, bobcats, and monarch butterflies in the woods

The Tenkiller Wildlife Management Area covers about 2,590 acres on the lake’s southwest shoreline, where oak-hickory uplands meet a riparian corridor of willow, sycamore, and birch.

White-tailed deer, wild turkey, bobcat, coyote, and gray fox work the surrounding woods. Around the water, you’ll find Canada geese, monarch butterflies, warblers, otters, mink, and beaver.

The mix of habitat types draws hunters, birders, and nature photographers who all want something different and mostly manage to stay out of each other’s way.

Ten marinas and 24 boat ramps around the water

Getting on the lake is not a problem. Ten marinas circle the water with boat rentals, fuel, repairs, and slip rentals.

Twenty-four public boat ramps give you easy access at almost any point along the shoreline. Pontoon boats, ski boats, jet skis, and kayaks are all available through various marinas.

Houseboats and sailboats are welcome too.

Through the summer months, the lake runs full of skiers, wakeboarders, tubers, and swimmers, and there’s enough water that it rarely feels crowded.

75 miles from Tulsa, with Cherokee history nearby

Lake Tenkiller sits about 75 miles southeast of Tulsa and 150 miles east of Oklahoma City. The nearby towns of Gore, Tahlequah, and Vian cover your dining, shopping, and local interest needs.

Tahlequah is the capital of the Cherokee Nation and home to the Cherokee Heritage Center, which gives the whole area an added layer of history worth a few hours of your time.

Whether you’re planning a day trip or a week-long stay, the lake has camping, cabins, and cottages across a wide range of budgets.
