They came from many different places – some from the Canadian fur corporations at Hudson Bay, some from the Pacific Northwest ( see also : Maritime fur trade ), and some from the midwestern United States. Most did not stay in the area for long, as they failed to find significant resources. The first glowing reports of country rich with thousands of game animals came in 1806 when Meriwether Lewis and William Clark returned from their two-year expedition. Their journals described lands amply stocked with thousands of buffalo, beaver, and river otter; and also an abundant population of sea otters on

The Missouri's nickname, the "Big Muddy", was inspired by its enormous loads of sediment or silt – some of the largest of any North American river. In its pre-development state, the river transported some 175 to 320 million short tons (159 to 290 million metric tons) per year. The construction of dams and levees has drastically reduced this to 20 to 25 million short tons (18 to 23 million metric tons) in

Forested areas of the watershed, mostly second-growth , total about 43,700 square miles (113,000 km ). Urban areas, on the other hand, comprise less than 13,000 square miles (34,000 km ) of land. Most built-up areas are along the main stem and a few major tributaries, including
9300-456: The basin relied heavily on the bison as a food source, and their hides and bones served to create other household items. In time, the species came to benefit from the indigenous peoples' periodic controlled burnings of the grasslands surrounding the Missouri to clear out old and dead growth. The large bison population of the region gave rise to the term great bison belt , an area of rich annual grasslands that extended from Alaska to Mexico along
9424-410: The basin. As one of the continent's most significant river systems, the Missouri's drainage basin borders on many other major watersheds of the United States and Canada. The Continental Divide , running along the spine of the Rocky Mountains, forms most of the western border of the Missouri watershed. The Clark Fork and Snake River , both part of the Columbia River basin, drain the area west of
9548-704: The capital of North Dakota, where the Heart River joins from the west. It slows into the Lake Oahe reservoir just before the Cannonball River confluence. While it continues south, eventually reaching Oahe Dam in South Dakota , the Grand , Moreau and Cheyenne Rivers all join the Missouri from the west. The Missouri makes a bend to the southeast as it winds through the Great Plains, receiving
9672-585: The center of Native American wealth and trade lay along the Missouri River in the Dakotas region on its great bend south. A large cluster of walled Mandan, Hidatsa and Arikara villages situated on bluffs and islands of the river was home to thousands, and later served as a market and trading post used by early French and British explorers and fur traders. Following the introduction of horses to Missouri River tribes, possibly from feral European-introduced populations, Natives' way of life changed dramatically. The use of
9796-464: The chiefs back to North America. Fort Orleans was either abandoned or its small contingent massacred by Native Americans in 1726. The French and Indian War erupted when territorial disputes between France and Great Britain in North America reached a head in 1754. By 1763, France's army in North America had been defeated by a combined British-American force and was forced to sue for peace. In
9920-462: The continental ice sheets diverted the river and its tributaries, causing them to pool up into large temporary lakes such as Glacial Lakes Great Falls , Musselshell and others. As the lakes rose, the water in them often spilled across adjacent local drainage divides, creating now-abandoned channels and coulees including the Shonkin Sag , 100 miles (160 km) long. When the glaciers retreated,
10044-649: The country's westward expansion , Fort Leavenworth was a forward destination for thousands of soldiers, surveyors, immigrants, American Indians , preachers and settlers who passed through. Today, the garrison supports the US Army Training and Doctrine Command (TRADOC) by managing and maintaining the home of the US Army Combined Arms Center (CAC). CAC's mission involves leader development, collective training, and Army doctrine and battle command (current and future). Fort Leavenworth
10168-544: The early 1790s. In 1795 the Spanish chartered the Company of Discoverers and Explorers of the Missouri, popularly referred to as the "Missouri Company", and offered a reward for the first person to reach the Pacific Ocean via the Missouri. In 1794 and 1795 expeditions led by Jean-Baptiste Truteau and Antoine Simon Lecuyer de la Jonchšre did not even make it as far north as the Mandan villages in central North Dakota. Arguably
10292-540: The early history of the fort, including some of the Custer family. In 1881, Gen. William T. Sherman established the School of Application for Cavalry and Infantry. That school evolved into the U.S. Army Command and General Staff College . The Western Branch National Military Home (" old soldiers' home "), now called the Veterans Medical Center, or Dwight D. Eisenhower Medical Center Historic District
10416-430: The eastern flank of the Continental Divide. However, after the arrival of Europeans in North America, both the bison and the Native Americans saw a rapid decline in population. Massive over-hunting for sport by colonists eliminated bison populations east of the Mississippi River by 1833 and reduced the numbers in the Missouri basin to a mere few hundred. Foreign diseases brought by settlers, such as smallpox , raged across
10540-486: The eastern terminus of the First transcontinental railroad via a ferry ride across the Missouri between Council Bluffs, Iowa , and Omaha. The Hannibal Bridge became the first bridge to cross the Missouri River in 1869, and its location was a major reason why Kansas City became the largest city on the river upstream from its mouth at St. Louis. True to the then-ideal of Manifest Destiny , over 500,000 people set out from
10664-651: The end of the Pleistocene . During the end of the last glacial period , large migration of humans were taking place, such as those via the Bering land bridge between the Americas and Eurasia. Over centuries, the Missouri River formed one of these main migration paths. Most migratory groups that passed through the area eventually settled in the Ohio Valley and the lower Mississippi River Valley, but many, including
10788-423: The first European settlement of any kind on the Missouri River, near present-day Brunswick, Missouri , in 1723. The following year Bourgmont led an expedition to enlist Comanche support against the Spanish, who continued to show interest in taking over the Missouri. In 1725 Bourgmont brought the chiefs of several Missouri River tribes to visit France. There he was raised to the rank of nobility and did not accompany
10912-525: The horse allowed them to travel greater distances, and thus facilitated hunting, communications, warfare, the Siouxoan genocide and expulsion of many tribes,and the abundance of trade. Once, tens of millions of American bison (commonly called buffalo), one of the keystone species of the Great Plains and the Ohio Valley, roamed the plains of the Missouri River basin. Most Native American nations in
11036-477: The industry continued well into the 1840s, but in others such as the Platte River valley, declines of the beaver population contributed to an earlier demise. The fur trade finally disappeared in the Great Plains around 1850, with the primary center of industry shifting to the Mississippi Valley and central Canada. Despite the demise of the once-prosperous trade, however, its legacy led to the opening of
11160-507: The land rises about 10 feet per mile (1.9 m/km) from east to west. The elevation is less than 500 feet (150 m) at the eastern border of the watershed, but is over 3,000 feet (910 m) above sea level in many places at the base of the Rockies. The Missouri's drainage basin has highly variable weather and rainfall patterns, Overall, the watershed is defined by a continental climate with warm, wet summers and harsh, cold winters. Most of
11284-561: The land, decimating Native American populations. Left without their primary source of sustenance, many of the remaining indigenous people were forced onto resettlement areas and reservations, often at gunpoint. In May 1673, the French-Canadian explorer Louis Jolliet and the French explorer Jacques Marquette left the settlement of St. Ignace on Lake Huron and traveled down the Wisconsin and Mississippi Rivers, aiming to reach
11408-679: The lower Missouri valley is now a populous and highly productive agricultural and industrial region, heavy development has taken its toll on wildlife and fish populations as well as water quality. From the Rocky Mountains, three streams rise to form the headwaters of the Missouri River: The Missouri River officially starts at the confluence of the Jefferson and Madison in Missouri Headwaters State Park near Three Forks, Montana , and
11532-430: The lowest was 41,690 cu ft/s (1,181 m /s) in 2006. Extremes of the flow vary even further. The largest discharge ever recorded was over 750,000 cu ft/s (21,000 m /s) on July 31, 1993, during a historic flood . The lowest, a mere 602 cu ft/s (17.0 m /s) – caused by the formation of an ice dam – was measured on December 23, 1963. The Rocky Mountains of southwestern Montana at
11656-546: The most longstanding and violent of the American Indian Wars . During the 20th century, the Missouri River basin was extensively developed for irrigation, flood control, and the generation of hydroelectric power . Fifteen dams impound the main stem of the river, with hundreds more on tributaries. Meanders have been cut off and the river channelized to improve navigation, reducing its length by almost 200 miles (320 km) from pre-development times. Although
11780-534: The most successful of the Missouri Company expeditions was that of James MacKay and John Evans . The two set out along the Missouri, and established Fort Charles about 20 miles (32 km) south of present-day Sioux City as a winter camp in 1795. At the Mandan villages in North Dakota, they forcefully expelled several British traders, and while talking to the populace they pinpointed the location of
11904-436: The mouth of the Platte River. It is unclear exactly how far Bourgmont traveled beyond there; he described the blond-haired Mandans in his journals, so it is likely he reached as far as their villages in present-day North Dakota. Later that year, Bourgmont published The Route To Be Taken To Ascend The Missouri River , the first known document to use the name "Missouri River"; many of the names he gave to tributaries, mostly from
12028-442: The mouth, is 21,920 cu ft/s (621 m /s). This is from a drainage area of 186,400 sq mi (483,000 km ), or 35% of the total river basin. At Kansas City, 366.1 miles (589.2 km) from the mouth, the river's average flow is 55,400 cu ft/s (1,570 m /s). The river here drains about 484,100 sq mi (1,254,000 km ), representing about 91% of the entire basin. The lowermost gage with
12152-505: The native tribes that lived along them, are still in use today. The expedition's discoveries eventually found their way to cartographer Guillaume Delisle , who used the information to create a map of the lower Missouri. In 1718, Jean-Baptiste Le Moyne, Sieur de Bienville requested that the French government bestow upon Bourgmont the Cross of St. Louis because of his "outstanding service to France". Bourgmont had in fact been in trouble with
12276-543: The north before crossing into North Dakota where the Yellowstone River , its greatest tributary by volume, joins from the southwest. At the confluence, the Yellowstone is actually the larger river. The Missouri then meanders east past Williston and into Lake Sakakawea , the reservoir formed by Garrison Dam . Below the dam the Missouri receives the Knife River from the west and flows south to Bismarck ,
12400-526: The one which produced the 1972 Black Hills flood through Rapid City, South Dakota . Winter temperatures in the northern and western portions of the basin typically drop to −20 °F (−28.9 °C) or lower every winter with extremes as low as −60 °F (−51.1 °C), while summer highs occasionally exceed 100 °F (37.8 °C) in all areas except the higher elevations of Montana, Wyoming and Colorado. Extreme maxima — almost all prior to 1960 — have exceeded 115 °F (46.1 °C) in all US states in
12524-651: The outbreak of the Civil War , Camp Lincoln was established on post as a reception and training station for Kansas volunteers. In 1864, news of the approach of Confederate General Sterling Price prompted construction of Fort Sully, a series of earthworks for artillery emplacements on Hancock Hill, overlooking what is now the Fort Leavenworth National Cemetery . (See Fort Sully (Fort Leavenworth) ). However, Price's forces never reached Fort Leavenworth, having met defeat at Westport , which
12648-467: The present day. Much of this sediment is derived from the river's floodplain , also called the meander belt; every time the river changed course, it would erode tons of soil and rocks from its banks. However, damming and channeling the river has kept it from reaching its natural sediment sources along most of its course. Reservoirs along the Missouri trap roughly 36.4 million short tons (33.0 million metric tons) of sediment each year. Despite this,
12772-424: The reservoirs dramatically reduce peak flows and increase low flows. Evaporation from reservoirs significantly reduces the river's runoff, causing an annual loss of over 3 million acre-feet (3.7 km ) from mainstem reservoirs alone. The United States Geological Survey operates fifty-one stream gauges along the Missouri River. The river's average discharge at Bismarck, 1,314.5 miles (2,115.5 km) from
12896-640: The river it was largely populated by slave-owning southerners following the Boone's Lick Road . The major trails for the opening of the American West all have their starting points on the river, including the California , Mormon , Oregon , and Santa Fe trails. The first westward leg of the Pony Express was a ferry across the Missouri at St. Joseph, Missouri . Similarly, most emigrants arrived at
13020-544: The river still transports more than half the total silt that empties into the Gulf of Mexico; the Mississippi River Delta , formed by sediment deposits at the mouth of the Mississippi, constitutes a majority of sediments carried by the Missouri. Archaeological evidence, especially in Missouri, suggests that human beings first inhabited the watershed of the Missouri River between 10,000 and 12,000 years ago at
13144-498: The river town of Independence, Missouri , to their various destinations in the American West from the 1830s to the 1860s. These people had many reasons to embark on this strenuous year-long journey – economic crisis, and later gold strikes including the California Gold Rush , for example. For most, the route took them up the Missouri to Omaha, Nebraska, where they would set out along the Platte River , which flows from
13268-453: The sediments that now underlie much of the drainage basin of the Missouri River. This Laramide uplift caused the sea to retreat and laid the framework for a vast drainage system of rivers flowing from the Rocky and Appalachian Mountains , the predecessor of the modern-day Mississippi watershed. The Laramide Orogeny is essential to modern Missouri River hydrology , as snow and ice melt from
13392-670: The size of the Canadian province of Quebec , the watershed encompasses most of the central Great Plains, stretching from the Rocky Mountains in the west to the Mississippi River Valley in the east and from the southern extreme of western Canada to the border of the Arkansas River watershed. Compared with the Mississippi River above their confluence, the Missouri is twice as long and drains an area three times as large. The Missouri accounts for 45 percent of
13516-519: The treaty and in 1800 secretly returned Louisiana to Napoleonic France in the Third Treaty of San Ildefonso . This transfer was so secret that the Spanish continued to administer the territory. In 1801, Spain restored rights to use the Mississippi and New Orleans to the United States. Fearing that the cutoffs could occur again, President Thomas Jefferson proposed to buy the port of New Orleans from France for $ 10 million. Instead, faced with
13640-533: The upper Mississippi, drain most of the area bordering the eastern side of the Missouri River basin. Finally, on the south, the Ozark Mountains and other low divides through central Missouri, Kansas and Colorado separate the Missouri watershed from those of the White River and Arkansas River, also tributaries of the Mississippi River. Over 95 significant tributaries and hundreds of smaller ones feed
13764-506: The various fur enterprises, namely Hudson's Bay . Fort Raymond was later replaced by Fort Lisa at the confluence of the Missouri and Yellowstone in North Dakota; a second fort also called Fort Lisa was built downstream on the Missouri River in Nebraska. In 1809 the St. Louis Missouri Fur Company was founded by Lisa in conjunction with William Clark and Pierre Choteau, among others. In 1828,
13888-489: The war, they dominated staffs throughout the AEF. In the years between the world wars, graduates included such officers as Dwight D. Eisenhower , Omar Bradley and George S. Patton . During World War II , some 19,000 officers completed various courses at Fort Leavenworth. By the end of 1943, commanders and staffs of 26 infantry, airborne and cavalry divisions had trained as teams at the school. General Michael Joe Costello of
14012-442: The watershed receives an average of 8 to 10 inches (200 to 250 mm) of precipitation each year. However, the westernmost portions of the basin in the Rockies as well as southeastern regions in Missouri may receive as much as 40 inches (1,000 mm). The vast majority of precipitation occurs in summer in most of the lower and middle basin, although the upper basin is known for short-lived but intense summer thunderstorms such as
14136-447: The watershed's southeastern portion – include Omaha, Nebraska , north of the confluence of the Missouri and Platte Rivers; Kansas City, Missouri – Kansas City, Kansas , at the confluence of the Missouri with the Kansas River; and the St. Louis metropolitan area, south of the Missouri River just below the latter's mouth, on the Mississippi. In contrast, the northwestern part of the watershed
14260-544: The watershed, with most leading a nomadic lifestyle and dependent on enormous bison herds that roamed through the Great Plains . The first Europeans encountered the river in the late seventeenth century, and the region passed through Spanish and French hands before becoming part of the United States through the Louisiana Purchase . The Missouri River was one of the main routes for the westward expansion of
14384-535: The west. Downstream, it begins to define the border between the states of Nebraska and Missouri , then flows between the states of Missouri and Kansas . The Missouri swings east at Kansas City , where the Kansas River enters from the west, and so on into north-central Missouri. To the east of Kansas City, the Missouri receives, on the left side, the Grand River . It passes south of Columbia and receives
14508-615: Was also the base of African-American soldiers of the U.S. 10th Cavalry Regiment of the United States Army, formed on 21 September 1866 at Fort Leavenworth. They became known as Buffalo Soldiers , nicknamed by the Native American tribes whom they fought. The term eventually was applied to all of the African-American regiments formed in 1866. The garrison commander is a colonel reporting via IMCOM West to
14632-465: Was destroyed by fire in December 2001. The first Protestant chapel, Memorial Chapel, was built by prison labor in 1878 of stone quarried on post. The round window behind the chapel's front altar was intentionally installed slightly askew by an inmate who was angry at his work boss. This chapel has brass cannon embedded in the walls at the sides of the church, and photos of many of the officers involved in
14756-554: Was established in 1885 as part of the National Home for Disabled Volunteer Soldiers system. The soldier home is closely associated with the nearby cemetery that became the Fort Leavenworth National Cemetery in 1973. World War I was the first opportunity to evaluate the impact of Sherman's school. Graduates excelled in planning complex American Expeditionary Forces operations. By the end of
14880-675: Was hauled overland, most transport to and from the gold fields was done through the Missouri and Kansas Rivers, as well as the Snake River in western Wyoming and the Bear River in Utah, Idaho, and Wyoming. It is estimated that of the passengers and freight hauled from the Midwest to Montana, over 80 percent were transported by boat, a journey that took 150 days in the upstream direction. A route more directly west into Colorado lay along
15004-613: Was located on Scott Avenue, south of the Post Chapel with initial strength of 14 officers and 174 enlisted men. The Cantonment almost immediately increased in importance as it became the eastern terminus for the Santa Fe Trail and Oregon Trail . After Indian Removal Act of 1830 attempted to remove all Indians west of the Missouri–Kansas border, the fort which is west of the border assumed even more importance. In 1832, it
15128-411: Was renamed "Fort Leavenworth". Between 1832 and 1834, the Rookery was built as bachelor officer quarters. The Rookery is the oldest building in Kansas and would be the office of the first territorial governor and thus the first capitol in Kansas from 1854 to 1855 when the capitol was moved to Pawnee, Kansas . In 1836, William Clark at the fort presided over the transfer of Indian land directly across
15252-457: Was such that the water was made muddy by it and could not clear itself." They recorded Pekitanoui or Pekistanoui as the local name for the Missouri. However, the party never explored the Missouri beyond its mouth, nor did they linger in the area. In addition, they later learned that the Mississippi drained into the Gulf of Mexico and not the Pacific as they had originally presumed; the expedition turned back about 440 miles (710 km) short of
15376-548: Was the incident that set off the French and Indian War ). The French abandoned the fort after ceding its territory to Louisiana (New Spain) at the conclusion of the French and Indian War. Early American explorers on the Missouri River to visit the area of Fort de Cavagnal include Lewis and Clark on 26–29 June 1804 and Stephen Harriman Long in 1819. The fort location had been chosen then because of its proximity to
