Appalachian Folklore & Myths Series – The Rivesville River Monster: Ogua, Giant Turtles, and the Stories Marion County Tells Itself
On a warm summer night at Rivesville in Marion County, the Monongahela River looks almost tame. Barges push coal up toward Pittsburgh. Fishermen sit on the bank near the mouth of Paw Paw Creek or lean against the rail of the pedestrian walkway, watching their lines disappear into the dark water. It is an ordinary Appalachian river town scene, right up until someone mentions the monster that is supposed to live in the bend.
Locals and travel writers call that creature the Ogua. In different tellings it is a twenty foot turtle, a reddish brown river beast, or a two headed reptile that drags deer into the channel and disappears without a trace. Modern accounts anchor it very specifically to the confluence at Rivesville and point visitors to the bridge as the best place to scan the water.
This article does not try to prove that anything impossible swims below the surface at Rivesville. Instead it traces how a handful of colonial era rumors and a 1983 night fishing trip turned into one of northern West Virginia’s most persistent pieces of river folklore.
A frontier boy and a river beast
The oldest story that modern writers connect to the Ogua legend comes from the mid eighteenth century, decades before there was a town called Rivesville.
According to an account preserved by historian Michael Newton, members of the Taylor and Nichols families were living along the Monongahela in October 1746 when disaster struck. A twelve year old Nichols boy was fishing on the river when something in the water seized him and pulled him under. Witnesses later described the attacker as a turtle larger than a bear. Within days, one of the Nichols daughters reported hearing a huge animal, “bigger than a sow,” rubbing against the family cabin at night. The Taylors and Nichols packed up and left the valley.
Another early account comes from farther west, near the confluence of the Ohio and Muskingum Rivers. A young man stationed at Fort Harmar, at present day Marietta, Ohio, wrote home about “an animal in this country which excites the imagination of all who have had an opportunity to view it.” In his description the creature lay in deer paths at night, then lashed out with a tail fifteen feet long, wrapped the deer, and dragged it into the river to drown and devour it. He claimed that men from the fort once killed such a beast and found it to have two heads and a weight of more than four hundred pounds.
Neither of these stories uses the word Ogua, and both read today like classic frontier tall tales. Historian Gregory Evans Dowd has argued that the borderlands of early America were a perfect breeding ground for such rumors. Communities depended on travelers, traders, and scattered letters for news. Strange or half understood events spread from cabin to cabin, changing a little with each retelling until they settled into legends that were hard to untangle from fact.
The boy in the river and the two headed beast at Fort Harmar belong to that world. They also planted the seeds for later writers who would go looking for a historical backstory for Marion County’s river monster.
From river rumor to a named monster
The name Ogua appears much later. Modern summaries often say it comes from a Delaware or Shawnee word for a great water creature, but the exact linguistic trail is blurry. The Clio public history entry on the Monongahela River monster carefully notes that the term is “supposedly” borrowed from Native peoples and treats that etymology as part of the legend rather than a proven fact.
By the late twentieth century, Ogua had become the standard label for a monstrous animal said to haunt the Monongahela and nearby rivers. Cryptid encyclopedias describe it as a reddish brown, twenty foot long, turtle like beast with multiple heads and a powerful tail, and they link it directly to both the colonial stories and to a much more recent series of sightings near Rivesville.
A key moment in that process came in 1999, when writer David Cain published an article titled “Ogua: The Rivesville River Monster” in Wonderful West Virginia magazine. Cain pulled together the Nichols and Fort Harmar accounts, interviewed modern fishermen, and treated the Ogua as a thread connecting eighteenth century rumor to late twentieth century anxiety along a changing industrial river.
By the time Cain’s article appeared, the Ogua was more than a single monster. It had become a way to talk about the Monongahela itself and the history that had soaked into its banks.
A coal miner’s night on the Monongahela
The story that gives the Ogua its most precise location in Marion County takes place on a summer night in 1983.
According to Cain’s article and later summaries, a Fairmont coal miner named John Edward White went night fishing for channel catfish at the point where Paw Paw Creek flows into the Monongahela at Rivesville. He was sitting close to the water when he noticed small waves slapping the bank. Then the fish he had been hoping to catch began to flail and churn near the mouth of the creek, as if something unseen was driving them toward the shallows.
White backed away as a large fin rose from the water only a short distance from his spot on the bank. He later estimated that fin to be six to eight feet high. As he retreated farther he caught a glimpse of a long, serpentine tail and the mass of a large animal as it swept out of the water and disappeared again into the river. Shaken, he left the site and swore never to fish there again.
On May 15, 1983, the Times West Virginian ran a story on what it called the “Rivesville River Monster,” quoting White and other fishermen who reported seeing a reddish brown creature twenty feet long with a serpent like head, a mouth full of sharp teeth, and a long flat tail. Some witnesses compared it directly to the old Ogua stories and said that older residents had been talking about a similar beast for years. Others thought this monster might be unique to Rivesville.
One jeweler interviewed in the same article reported that the animal “did not trouble him” even when it surfaced nearby. The monster, in other words, frightened people but did not actually attack anyone.
Cain and later writers point out that if there was a real animal behind the 1983 sightings, the most likely candidate is an alligator snapping turtle or an escaped alligator that somehow made its way up the river from the Gulf Coast and grew to unusual size in the Monongahela. Alligator snapping turtles can reach impressive weights and spend much of their lives on river bottoms, but they do not normally grow as large or behave quite as dramatically as the stories suggest.
Whether White encountered a giant turtle, a misjudged log, or something stranger, his night on the river fixed the Ogua story squarely at Rivesville and gave local tourism writers a vivid modern episode to work with.
Monsters, mines, and Marion County tourism
Today, if you browse the Marion County Convention and Visitors Bureau’s “Monsters of Marion County” blog, the Ogua appears alongside other local legends like Monongy, the Grant Town Goon, and the White Thing. The CVB calls the Ogua a terrifying beast of the Monongahela and describes it in two main ways. In one telling it is a twenty foot turtle that can lunge onto shore and crush deer. In another it is a giant beaver like creature covered in reddish brown fur, capable of whistling or screeching loudly as it eats.
The same CVB post treats White’s experience as the moment when the “Rivesville River Monster” was settled in public imagination. The author notes that some fishermen described a creature that sounded like the traditional Ogua, while others insisted it was something new and unique to that bend in the river. Either way, the piece invites visitors to rent a pontoon boat, head out from nearby marinas, and see if they can glimpse the monster for themselves.
Regional writers have picked up the theme. A feature from the Upper Monongahela River regional site points out that the Monongahela now boasts at least three river monster legends and quotes cryptid researcher Les O’Dell, who calls the area a magnet for Bigfoot sightings, stories of giant skeletons, and even a “vegetable man” seen in the woods near Rivesville in 1968. In that context the Ogua becomes one member of a crowded cast of oddities associated with the Monongahela valley.
Tourism sites in Pittsburgh and Morgantown echo the same pattern. They mention an amphibious beast that is part alligator, part snake, and part turtle, lurking beneath the rivers that link West Virginia, western Pennsylvania, and northern Appalachia.
For Marion County, that mix of frontier rumor, 1980s fish stories, and twenty first century cryptid culture has turned the Ogua into both a monster and a marketing hook.
From buffalo country to deindustrial river
The Clio entry on the Monongahela River monster uses the Ogua to make a broader point about how people experience fear and uncertainty in changing landscapes.
On the colonial borderland, where the Nichols and Taylor families lived, European settlers were still learning what kinds of animals inhabited North American rivers. Accounts of huge turtles or strange reptiles were believable partly because the newcomers did not yet know the limits of the continent’s wildlife. Stories about a child dragged into the river functioned as warnings about real dangers in an unfamiliar environment, whether or not the particular details were accurate.
By the time John White sat down to fish at Rivesville in 1983, the Monongahela valley had been transformed by more than a century of coal mining, industrialization, and power generation. The river carried barges of coal to power stations, and the skyline at Rivesville included the stacks and structures of the Monongahela Power plant. The 1980s were also years of mine closures and industrial downsizing across northern West Virginia.
Clio’s author suggests that Ogua sightings in that period reflected a different kind of uncertainty. In a deindustrializing landscape, where jobs were disappearing and the river’s role in local life was shifting, stories about a massive unseen predator in the water captured anxieties that were hard to express in political or economic terms. The monster that once symbolized the unknown wilderness now floated beneath a river lined with power stations and slate dumps.
Seen that way, the Ogua connects two very different Marion County worlds. In one, a settler family flees the river after losing a child. In the other, a coal miner steps back from the bank as a fin rises in front of him and the fish scatter.
Explanations and what remains
Skeptics point out that every element of the Ogua story can be explained without invoking a supernatural monster.
Large alligator snapping turtles, while rare, do exist and have jaws powerful enough to injure or kill small animals. Misjudged logs, surfacing fish, waves from passing barges, and tricks of light on the water could account for some of the stranger sightings. The dramatic two headed, four hundred pound river beast described in the Fort Harmar letter fits neatly into an eighteenth century literary tradition of marvels and curiosities rather than into zoology.
At the same time, the persistence of the Ogua in local storytelling tells us something important about how people connect to place. For residents of Marion County, the Monongahela is not just a channel for coal or a line on a map. It is a living presence that has taken lives through floods and accidents and sustained livelihoods through fishing and shipping. Giving the river a monster is one way of acknowledging that power.
Cryptid hunters who come to Rivesville today are unlikely to find a two headed turtle. What they will find is a town that illustrates several layers of Appalachian history at once: an industrial river with barges still moving coal, a community shaped by mines and power plants, and a landscape where frontier rumors still echo in modern tourism campaigns.
Watching the water at Rivesville
If you stand on the pedestrian walkway at Rivesville on a quiet evening, you can look upstream toward Fairmont and downstream toward the Pennsylvania line. The Monongahela’s surface ripples with boat wakes and the wake of fish rolling under. The power station has fallen silent, but the river keeps flowing past its foundations.
The Ogua may be nothing more than shadows, old fears, and the occasional very large turtle. Or it may remain, for some people, a real creature that explains why the river sometimes feels deeper and more dangerous than it looks. Either way, the legend of the Ogua has become part of how Marion County tells its own story, a reminder that in Appalachia the line between history and folklore often runs right down the middle of the river channel.

Author Notes: Ogua lives at a crossroads I love to write about, where river industry, folklore, and coalfield memory overlap. If your family has stories about the Rivesville river monster or other Monongahela creatures, I would be honored to hear them as this series grows.
