The Mississippi River System, also referred to as the Western Rivers, is a mostly riverine network of the United States which includes the Mississippi River and connecting waterways. The Mississippi River is the largest drainage basin in the United States. Given their flow volumes, major Ohio River tributaries like the Allegheny. The mouth of the Ohio River, where it feeds into the Mississippi, is located where Cairo, Illinois meets Ballard County, Kentucky. Along the way, it has nearly a. The Ohio River becomes a tributary of the Mississippi River directly over the Appalachians and the northeastern United States has led.
The Indians and early explorers and settlers of the region also 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. The river had great significance in the history of the Native Americansas numerous civilizations formed along its valley.
Its waters connected communities. In the five centuries before European conquest, the Mississippian culture built numerous regional chiefdoms and major earthwork mounds in the Ohio Valley, such as Angel Mounds near Evansville, Indianaas well as in the Mississippi Valley and the Southeast.
The OsageOmahaPonca and Kaw lived in the Ohio Valley, but under pressure from the Iroquois to the northeast, migrated west of the Mississippi River in the 17th century to territory now defined as MissouriArkansas and Oklahoma.
French fur traders operated in the area, and France built forts along the Allegheny River. He traveled from Canada and entered the headwaters of the Ohio, traveling as far as the Falls of Ohio at present-day Louisville before turning back. He returned to explore the river again in other expeditions. An Italian cartographer traveling with him created the first map of the Ohio River.
La Salle claimed the Ohio Valley for France. InGreat Britain established the Ohio Company to settle and trade in the area. Exploration of the territory and trade with the Indians in the region near the Forks brought British colonials from both Pennsylvania and Virginia across the mountains,and both colonies claimed the territory. The movement across the Allegheny Mountains of British settlers and the claims of the area near modern day Pittsburgh led to conflict with the French, who had forts in the Ohio River Valley.
Infollowing the Seven Years' WarFrance ceded the area to Britain, and thus to the settlers in the colonies of Britain. The Treaty of Fort Stanwix opened Kentucky to colonial settlement and established the Ohio River as a southern boundary for American Indian territory. This appeased the Canadien British subjects but angered the Thirteen Colonies. Lord Dunmore's War south of the Ohio river also contributed to giving the land north to Quebec to stop further encroachment of the British colonials on native land.
Built between andthe Wheeling Suspension Bridge was the first bridge across the river and a crucial part of the National Road. The economic connection of the Ohio Country to the East was significantly increased in when the National Road being built westward from Cumberland, Maryland reached Wheeling, Virginia now West Virginiaproviding an easier overland connection from the Potomac River to the Ohio River. For a brief time, untilit was the world's largest suspension bridge.
Fortunately, the bridge was not blown up during the American Civil War. The bridge has been improved in andand remains in use as the oldest vehicular suspension bridge in the U. 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. If the land loss continues at the pace its going, all these benefits can vanish. It spans across miles, making it one of the longest distributaries of the Mississippi River. The name of the river translated into English is "long river," which derives from the Native American word.
The river is important for commerce because it shortens the distance to the Gulf of Mexico, also saving companies time and money. The abundance of resources and overall size attracted these individuals to settle near the water. They named the Mississippi River.
The retention time from Lake Itasca to the Gulf is typically about 90 days. These images demonstrate that the plume did not mix with the surrounding sea water immediately.
Instead, it stayed intact as it flowed through the Gulf of Mexico, into the Straits of Floridaand entered the Gulf Stream. The Mississippi River water rounded the tip of Florida and traveled up the southeast coast to the latitude of Georgia before finally mixing in so thoroughly with the ocean that it could no longer be detected by MODIS. The reduction in sediment transported down the Mississippi River is the result of engineering modification of the Mississippi, Missouri, and Ohio rivers and their tributaries by dams, meander cutoffsriver-training structures, and bank revetments and soil erosion control programs in the areas drained by them.
Through a natural process known as avulsion or delta switching, the lower Mississippi River has shifted its final course to the mouth of the Gulf of Mexico every thousand years or so.

This occurs because the deposits of silt and sediment begin to clog its channel, raising the river's level and causing it to eventually find a steeper, more direct route to the Gulf of Mexico. The abandoned distributaries diminish in volume and form what are known as bayous.

The currently active delta lobe is called the Birdfoot Delta, after its shape, or the Balize Deltaafter La Balize, Louisianathe first French settlement at the mouth of the Mississippi. The southernmost extent of this enormous glaciation extended well into the present-day United States and Mississippi basin. When the ice sheet began to recede, hundreds of feet of rich sediment were deposited, creating the flat and fertile landscape of the Mississippi Valley.
During the melt, giant glacial rivers found drainage paths into the Mississippi watershed, creating such features as the Minnesota RiverJames Riverand Milk River valleys. When the ice sheet completely retreated, many of these "temporary" rivers found paths to Hudson Bay or the Arctic Ocean, leaving the Mississippi Basin with many features "oversized" for the existing rivers to have carved in the same time period.
Ice sheets during the Illinoian Stageabouttoyears before present, blocked the Mississippi near Rock Island, Illinois, diverting it to its present channel farther to the west, the current western border of Illinois.
