The Mississippi River System, also referred to as the Western Rivers, is a mostly riverine Map of the course, watershed, and major tributaries of the Mississippi River . The Ohio River runs miles ( km) long, starting at the meeting of the Allegheny River and the Monongahela River in Pittsburgh, Pennsylvania;. The Ohio River becomes a tributary of the Mississippi River directly south of Cairo, Illinois, a small city on the spit of land where the rivers.
There, some continued on up the Missouri Riversome up the Mississippi, and some further west over land routes. In the early 19th century, river pirates such as Samuel Masonoperating out of Cave-In-Rock, Illinoiswaylaid travelers on their way down the river.
They killed travelers, stealing their goods and scuttling their boats. The folktales about Mike Fink recall the keelboats used for commerce in the early days of European settlement.
Trading boats and ships traveled south on the Mississippi to New Orleansand 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 the west, since the trek east over the Appalachian Mountains was long and arduous.
The need for access to the port of New Orleans by settlers in the Ohio Valley is one of the factors that led to the Louisiana Purchase in Because the river is the southern border of Ohio, Indiana, and Illinois, it was part of the border between free states and slave states in the years before the American Civil War.
The expression "sold down the river" originated as a lament of Upper South slaves, especially from Kentucky, who were shipped via the Ohio and Mississippi to cotton and sugar plantations in the Deep South.
Harriet Beecher Stowe 's Uncle Tom's Cabinthe bestselling novel that fueled abolitionist work, was the best known of the anti-slavery novels that portrayed such escapes across the Ohio. The times have been expressed by 20th-century novelists as well, such as the Nobel Prize -winning Toni Morrisonwhose novel Beloved was adapted as a film of the same name.
She also composed the libretto for the opera Margaret Garnerbased on the life and trial of an enslaved woman who escaped with her family across the river. The colonial charter for Virginia defined its territory as extending to the north shore of the Ohio, so that the riverbed was "owned" by Virginia. Where the river serves as a boundary between states today, Congress designated the entire river to belong to the states on the east and south, i.
Thus Wheeling Islandthe largest inhabited island in the Ohio River, belongs to West Virginia, although it is closer to the Ohio shore than to the West Virginia shore. Kentucky brought suit against Indiana in the early s because of the building of the Marble Hill nuclear power plant in Indiana, which would have discharged its waste water into the river. Supreme Court held that Kentucky's jurisdiction and, implicitly, that of West Virginia extended only to the low-water mark of 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 s, Kentucky challenged Illinois' right to collect taxes on a riverboat casino docked in Metropolisciting its own control of the entire river. A private casino riverboat that docked in Evansville, Indianaon 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 forwards, then reversing and going backwards 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 and Indiana in The collapse took the lives of 46 people who had been crossing on the bridge at the moment of its failure. The bridge had been built inand by was carrying too heavy a load for its design.

Pollution[ edit ] The Ohio River as a whole is ranked as the most polluted river in the US based on and data although the more industrial and regional Ohio tributary, Monongahela Riverranked behind 16 other American rivers for pollution at number 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.
Mouth of the Ohio, as it feeds into the Mississippi. The river then follows a roughly southwest and then west-northwest course until Cincinnati, before bending to a west-southwest course for most of its length. The course forms the northern borders of West Virginia and Kentucky ; and the southern borders of OhioIndiana and Illinoisuntil it joins the Mississippi River at the city of Cairo, Illinois.
Mississippi River System
At the confluencethe Ohio is considerably bigger than the Mississippi. Measured by long-term mean discharge in cubic feet per second and cubic meters per second, the Ohio River at Cairo: In both measures, the Ohio River water flow is higher than that of the Mississippi River. From a hydrographic perspective, the Ohio River is the main stream of the whole river system. List of major tributaries[ edit ] Natural-color satellite image of the Wabash-Ohio confluence.
Major tributaries of the river, indicated by the location of the mouths, include: The bottom of the river is composed of a thin layer of clay, silt, loam, and sand, which lay above a stratum of glacial outwash.
About miles of the river is able to be navigated, from Minneapolis-St. Paul to the Ohio River. The river sustains a large variety of marine life, including species of fish and 30 species of freshwater mussels.
It flows west to east starting in Colorado and dumping the Mississippi River. Its length of 1, miles allows it to flow through Colorado, Kansas, Oklahoma, and Arkansas. It is the sixth longest river in the US, the second longest tributary to the Mississippi River System, and the 45th longest river in the world. The river runs approximately miles km long, in the U.
The confluence of the rivers offers vistas that seem endless. The Illinois River is relatively shallow, just like the Mississippi. In addition, the Illinois River is a "managed" river, just as the Mississippi River is. Missouri River[ edit ] The Missouri River is a long stream that originates in southwest Montana and flows southeasterly for 2, miles; passing through six states before finally entering the Mississippi River at St.
The Missouri River was one of the main routes for the watershed expansion of the United States during the 19th century. The river is a location with the capacity to provide enough water for over five million people.
At its widest point, it is one mile wide at Smithland dam.
The average depth is 24 feet deep[ citation needed ] which allows multiple species of fish to live there safely. The water is also home to species of fish ranging from catfish to certain species of salmon and trout. On average the Ohio River transports over million tons of cargo.

Typically, the cargo being shipped are energy resources such as coal. Along with shipping energy resources, the Ohio River also creates energy with dams and other power generating facilities. There are 20 dams and 49 other power generating facilities on the Ohio River. The river also crosses through Oklahoma, Arkansas, and Louisiana where then it links into the Mississippi River.
The Red River is home to many oil fields with oil and gas production being one of the river's major aspects. The delta is home to massive amounts of wildlife, and attributed to the U. Over the last three centuries, the delta has continuously collapsed, due to human alterations of the river system. Natural protection of land is exacerbated the more the delta diminishes. The delta is important to the wildlife and people that it supports, along with the US economy.
