It is the third largest river by discharge volume in the United States and the largest tributary by volume of the north-south flowing Mississippi River, which divides the eastern from western United States. It is also the sixth oldest river on the North American continent. The river flows through or along

770-822: A whole is ranked as the most polluted river in the United States, based on 2009 and 2010 data. The more industrial and regional West Virginia/Pennsylvania tributary, the Monongahela River , ranked 17th for water pollution , behind 16 other American rivers. The Ohio again ranked as the most polluted in 2013, and has been the most polluted river since at least 2001, according to the Ohio River Valley Water Sanitation Commission (ORSANCO). The Commission found that 92% of toxic discharges were nitrates , including farm runoff and waste water from industrial processes such as steel production. The Commission also noted mercury pollution as an ongoing concern, citing

847-584: Is 1,310 miles (2,110 km) long and carries the largest volume of water of any tributary of the Mississippi. The Indians and early European explorers and settlers of the region often considered the Allegheny to be part of the Ohio. The forks (the confluence of the Allegheny and Monongahela rivers at what is now Pittsburgh) were considered a strategic military location by colonial French and British, and later independent American military authorities.

Viele made contact with Native American nations as far west as the Wabash River , in present-day Indiana. He and his company left Albany , traveling southbound and crossing portions of present-day New Jersey and eastern Pennsylvania. They apparently followed the west branch of the Susquehanna River into

1078-539: Is formed by the confluence of the Allegheny and Monongahela rivers at what is now Point State Park in Pittsburgh , Pennsylvania . From there, it flows northwest through Allegheny and Beaver counties, before making an abrupt turn to the south-southwest at the West Virginia –Ohio–Pennsylvania triple-state line (near East Liverpool, Ohio ; Chester, West Virginia ; and Ohioville, Pennsylvania ). From there, it forms

1155-599: The 1763 Treaty of Paris . The 1768 Treaty of Fort Stanwix with several tribes opened Kentucky to colonial settlement and established the Ohio River as a southern boundary for American Indian territory. In 1774 the Quebec Act restored the land east of the Mississippi River and north of the Ohio River to Quebec , in effect making the Ohio the southern boundary of Canada . This appeased French Canadians in Quebec but angered

1232-459: The American Civil War . One antebellum slave trader reported that they kept slaves chained two-by-two while navigating the Ohio, only when they reached the Mississippi could the slaves be unchained for a time, because "there was slavery on both sides of the boat." The expression "sold down the river" originated as a lament of Upper South slaves, especially from Kentucky, who were shipped via

1309-634: The Batts and Fallam expedition of 1671, and the Needham and Arthur expedition of 1673–74. In early autumn 1692, loyal English-speaking Dutchman Arnout Viele and a party of eleven companions from Esopus —Europeans, Shawnee , and a few loyal Delaware guides—were sent by the governor of New York to trade with the Shawnee and bring them into the English sphere of influence. Viele understood several Native American languages, which made him valuable as an interpreter. He

1386-636: The Forks of the Ohio at Pittsburgh to the Port of New Orleans at the mouth of the Mississippi on the Gulf of Mexico. Since the "canalization" of the river in 1929, the Ohio has not been a natural free-flowing river; today, it is divided into 21 discrete pools or reservoirs by 20 locks and dams for navigation and power generation. The name "Ohio" comes from the Seneca , Ohi:yo' , lit.  "Good River". In his Notes on

1463-619: The French National Natural History Museum . Charles III Le Moyne , second Baron de Longueuil (later the governor of Montreal and interim governor of New France ), commanded Fort Niagara from 1726 to 1733. He led an expedition of 442 men, including Native Americans, from Montreal to war against the Chickasaw who occupied territory on the lower part of the Mississippi River in the area claimed as La Louisiane . According to Gaston Pierre de Lévis , Duke de Mirepoix,

1540-700: The Kanawha River , they entered the Ohio River 444 miles (715 km) above the falls. The Virginia pioneers traced the northern boundary of Kentucky for five hundred miles (800 km), reaching the Mississippi River on June 7. They descended just below the mouth of the Arkansas River , where they were ambushed by a large company of Native Americans, Blacks and Frenchmen on July 2, 1742; one or two of Howard's men were killed. The rest were brought to New Orleans and imprisoned as spies. After two years in prison, Salling escaped on October 25, 1744, and returned on

1617-533: The Land Ordinance of 1784 , Thomas Jefferson proposed a new state called "Pelisipia", to the south of the Ohio River, which would have included parts of present-day Eastern Kentucky , Virginia and West Virginia . The river had great significance in the history of the Native Americans , as numerous prehistoric and historic civilizations formed along its valley. For thousands of years, Native Americans used

The water depth predictions are relative to each local flood plain based upon predicted rainfall in the Ohio River basin in five reports as follows: The water levels for the Ohio River from Smithland Lock and Dam to Cairo, Illinois, are predicted by the National Oceanic and Atmospheric Administration 's Lower Mississippi River Forecast Center. The largest tributaries of

1925-625: The Ohio Company was established in Virginia Colony to settle and trade in the Ohio River region. Exploration of the territory and trade with the Indians in the region near the Forks brought white colonists from both Pennsylvania and Virginia across the mountains, and both colonies claimed the territory. The movement across the Allegheny Mountains of Anglo-American settlers and the claims of

2002-466: The Potomac River to the Ohio River. The Wheeling Suspension Bridge was built over the river at Wheeling from 1847 to 1849, making the trip west easier. For a brief time, until 1851, it was the world's largest suspension bridge. The bridge survived the American Civil War , after having been improved in 1859. It was renovated again in 1872, and remains in use as the oldest vehicular suspension bridge in

2079-503: The keelboats used for commerce in the early days of American settlement. The Ohio River boatmen inspired performer Dan Emmett , who in 1843 wrote the song " The Boatman's Dance ". Trading boats and ships traveled south on the Mississippi to New Orleans , and sometimes beyond to the Gulf of Mexico and other ports in the Americas and Europe. This provided a much-needed export route for goods from

2156-637: The Allegheny River also as Ohi:yo' . Similarly, the Geographic Names Information System lists O-hee-yo and O-hi-o as variant names for the Allegheny. An earlier Miami-Illinois language name was also applied to the Ohio River, Mosopeleacipi ("river of the Mosopelea " tribe). Shortened in the Shawnee language to pelewa thiipi , spelewathiipi or peleewa thiipiiki ,

2233-464: The Mississippi River at Thebes, Illinois , which is upstream of the confluence, is 208,200 cu ft/s (5,897 m /s). The Ohio River flow is greater than that of the Mississippi River, so hydrologically the Ohio River is the main stream of the river system. The Ohio River is a naturally shallow river that was artificially deepened by a series of dams . The natural depth of the river varied from about 3 to 20 feet (1 to 6 m). The dams raise

2310-615: The Mornington syndicate, capitalized on the new transportations to downtown and purchased much of the land to create a community exclusively for Cincinnati's wealthy, selling old parcels to residents who met such criteria. In 1896, the village of Hyde Park was incorporated and was named after the affluent hamlet of Hyde Park in New York . In November 1903, Hyde Park was annexed by the City of Cincinnati. Almost immediately thereafter, it experienced

2387-671: The Natural Bridge), crossing Greenbrier River and landing at the New River . At New River, the Virginia explorers built a large bull boat frame and covered it with five buffalo skins. The first Englishmen to explore the region then followed the New River for 250 miles (400 km), until it became too dangerous to navigate. At a large waterfall, they traveled overland to the Coal River . Following

The residences are comparable in size and shape, generally built as two- story single-family houses with similar setbacks , while the district is surrounded by open land rather than closely packed residential neighborhoods in order to reduce light pollution for

2618-564: The Ohio River opened about the same time. Although such boats cruised on the Ohio River in an oval pattern up and down, the state of Kentucky soon protested. Other states had to limit their cruises to going forward, then reversing and going backward on the Indiana shore only. Both Illinois and Indiana have long since changed their laws to allow riverboat casinos to be permanently docked, with Illinois changing in 1999 and Indiana in 2002. The Silver Bridge at Point Pleasant, West Virginia , collapsed into

Its current gentle, waters clear, and bosom smooth and unbroken by rocks and rapids, a single instance only excepted." After the French and Indian War , Britain's trans-Appalachian Indian Reserve was divided by the river into colonial lands to the south and Native American lands to

3003-476: The U.S. Louisville was founded in 1778 as a military encampment on Corn Island (now submerged) by General George Rogers Clark at the only major natural navigational barrier on the river, the Falls of the Ohio . The Falls were a series of rapids where the river dropped 26 feet (7.9 m) in a stretch of about 2 miles (3.2 km). In this area, the river flowed over hard, fossil-rich beds of limestone . The outpost

The Ohio River is extensively industrialized and populated. Regular barge traffic carries cargoes of oil, steel and other industrial goods produced in the region. Major cities located along the northern and southern banks of the river include Pittsburgh, Pennsylvania ; Louisville, Kentucky ; Evansville, Indiana ; and Cincinnati, Ohio . The combined Allegheny-Ohio river

3927-417: The increasing size of steamships and barges on the river meant that the outdated locks could serve only the smallest vessels until well after the Civil War when improvements were made. The U.S. Army Corps of Engineers improvements were expanded again in the 1960s, forming the present-day McAlpine Locks and Dam . During the nineteenth century, emigrants from Virginia, North Carolina and Kentucky traveled by

Kentucky sued the state of Indiana in the early 1980s because of their construction of the never-completed Marble Hill Nuclear Power Plant in Indiana, which would have discharged its waste water into the river. This would have adversely affected Kentucky's water supplies. The U.S. Supreme Court held that Kentucky's jurisdiction (and, implicitly, that of West Virginia) extended only to

4081-407: The low-water mark of 1793 (important because the river has been extensively dammed for navigation so that the present river bank is north of the old low-water mark). Similarly, in the 1990s, Kentucky challenged Illinois's right to collect taxes on a riverboat casino docked in Metropolis , citing its own control of the entire river. A private casino riverboat that docked in Evansville, Indiana , on
