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.

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.

Fort Orleans was a French fort in colonial North America, the first fort built by any European country on the Missouri River. It was to be a linchpin in the vast New France empire stretching from Montreal to New Mexico. Occupied from 1723-1726, it was the first multi-year European settlement in...

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 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 .

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.
