Course



The longest river in the United States of America. Heads in Montana at the junction of the Jefferson River and the Madison River, near the mouth of the Gallatin River, then flows generally South-East to the Mississippi River North of St. Louis, Missouri. Forms parts of the South Dakota-Nebraska, Nebraska-Iowa, Nebraska-Missouri and Kansas-Missouri boundaries. The lowest elevation in Nebraska at 840 feet near Richardson.

The Lewis and Clark decision not to call the Jefferson the Missouri has spurred debate over what is the longest river in North America since the Missouri and Mississippi are nearly identical in length. With the Jefferson the Missouri would be the longest river.

Lewis (who had followed the Jefferson River to the Beaverhead River) said that on August 12, 1805, he visited Beaverhead tributary of Trail Creek just above Lemhi PassLemhi Pass

History


Name

The popular but erroneous conception that the name means "muddy water" arose from the fact that Marquette gave it the indigenous name "Pekitanoui" meaning "muddy". Early white explorers first called the stream "Missouri" after a tribe of Indians who lived on its banks and whose name meant "people with wooden canoes." (Robert Ramsay placename file). The variant name "Emasulia Sipiwi" means "river of boatmen" in the Peoria language.

Also known as: Big River, Emasulia sipiwi, Eomitai, Katapan Mene Shoska, Le Riviere des Missouri, Mini Sose, Missoury River, Ni-sho-dse, Nudarcha, Rio Misuri, Riviere de Pekitanoni, Riviere de Saint Philippe, Big Muddy, Le Missoui, Le Missouri, Le Riviere des Osages, Missures Flu, Miz-zou-rye River, Niutaci, Pekitanoui, River of the West, Yellow River.

 heard the Missouri rushing into the Mississippi.

Marquette wrote:

While conversing about these monsters sailing quietly in clear and calm water, we heard the noise of a rapid into which we were about to run. I never saw anything more terrific, a tangle of entire trees from the mouth of the Pekistanoui with such impetuosity that one could not attempt to cross it without great danger. The commotion was such that the water was made muddy by it and could not clear itself.


Pekitanoui is a river of considerable size, coming from the northwest, from a great distance; and it discharges into the Mississippi. There are many villages of savages along this river, and I hope by this means to discover the Vermillion or California Sea.


Marquette and Joliet referred to the river as "Pekistanoui" and they made a reference to a tribe who lived upstream on the river as "Oumessourita" which was pronounced "OO-Missouri."), (meaning "those who have dugout canoeCanoe

Marquette wrote that natives had told him that it was just a six day canoe trip up the river (about 60 miles) where it would be possible to portage over to another river that would take people to California.

It is unclear how far up the Missouri Bourgmont traveled. He is the documented first European discoverer of the Platte River. In his writings he described the blonde-haired Mandans, so it is possible that he made it as far north as their villages in central North Dakota.

. This federally-designated "Wild and Scenic River" is among the last unspoiled stretches of the Missouri, and exhibits the islands, bars, chutes and snags that once characterized the "Mighty Mo".

The dikes, revetments, and levees constructed by the Corps of Engineers as part of the Missouri River Navigation and Flood Control Project have transformed the once sprawling and constantly changing river into a narrower, deeper, fixed channel designed to more easily maintain the 735 mile navigation channel. The river carries a large amount of silt and sand, but high water velocity in the navigation channel normally prevents settling out and sand bar accumulations. As a result, unlike the Mississippi River, the Missouri River rarely requires dredging to maintain the navigation channel. The huge amounts of sediment in the Big Muddy have long provided a free source of sand, mined by commercial dredgers to be used in concrete and asphalt for construction, mainly below Rulo, Nebraska. In recent years, the quantity of sand commercially dredged from the Missouri River has dramatically increased as Kansas City, Columbia, and St. Louis have grown. In 2000, 7.4 million tons of sand and gravel were dredged out of the navigation channel. As commercial sand dredging has increased, the Missouri River bed has gradually cut deeper into the flood plain. Between 1990 and 2005 the river around Kansas City, Missouri has degraded as much as 4.5 feet.

Traffic

Barge traffic has been steadily declining from 3.3 million tons in 1977 to 1.3 million tons in 2000. The declining barge traffic industry has stirred controversies over the management of the river and whether upstream dams should release more water to maintain commercial navigation standards.
