The Missouri River is the longest river in North America. It once had abundant braided channels, chutes, sloughs, sandbars, islands, aha backwater areas. Historically, the Missouri carried high loads of sediment, earning it the nickname "Big Muddy."

Wetlands may be created during major floods if the Missouri slices a new channel through the banks of a riverbend and diverts water into a natural containment area. Wetlands are nature's way of controlling floods and providing new habitats.

Sandbars are created when fast-flowing waters lose their energy while moving downstream and deposit sand and soils that are picked up from the river bottom and banks. Sandbars are a habitat for nesting terns and plovers.

Islands develop typically during floods when the river follows its older channel and breaks open a new channel to encircle a sandbar or piece of land. Islands are stable enough to support vegetation and a variety of wildlife, like eagles.

A Great American Riverway

The Missouri has a story like no other river. Beginning at the confluence of three tributaries at Three Forks, Montana, it flows southeast for over 2,300 miles before joining the Mississippi River a few miles north of St. Louis, Missouri. It was the great waterway of American Indians, fur trappers, Lewis and Clark, and early settlers. In the 1800s the river shared with the Oregon and Santa Fe trails the distinction of being one of the three main thoroughfares to the Far West.

For centuries this wild, unpredictable river transported tons of silt and rocky freight. Forced into much of its present course by glaciers the river rushed along their faces. Eventually, the glaciers receded. The river remained, continuing its job of transporting the Rocky Mountains to the Gulf of Mexico grain by grain. As it changed course, any permanence of its channel and banks was accidental. Its floodplain was a mixture of wetlands, sandbars, wet prairies, and bottomland forests.

The Lewis and Clark Expedition traveled along this section of the Missouri from late August to early September 1804, and again on their return trip in 1806. They explored landscape features like Spirit Mound, held a council with the Yankton Sioux, and wrote the first reports on pronghorns, mule deer, and prairie dogs, all previously unknown to western science.

Flooding—Doing What Comes Naturally During the time of westward expansion the Missouri River had a vast floodplain. It periodically overflowed its banks, creating new channels as the main one moved from side to side. A shifting channel was normal, especially below Yankton and downstream to the confluence with the Platte River. Typically, in April brief floods of one to two weeks occurred as a result of local snowmelt and spring rains. In June floods lasted longer and inundated larger portions of the plains when melting snowpack from the Rockies and rain from lower elevations swelled the Missouri beyond its banks.

Taming the Missouri—The Pick-Sloan Plan After a series of floods devastated farms and towns in the early 1940s, Congress enacted the Flood Control Act of 1944. A component known as the Pick-Sloan Plan called for construction of five dams along the Missouri. By the mid-1960s, after the dams were built and reservoirs filled, the river ceased to be the meandering and high sediment-carrying sculptor of scenery. Although seasonal floods no longer replenish the floodplains, dam-controlled fluctuations provide habitats for an amazing array of plants and animals.

Today two stretches of the Missouri River along the Nebraska-South Dakota border are vital remnants of the historic river. In 1978 and 1991 Congress preserved these free-flowing sections by designating them as the Missouri National Recreational River and adding them to the National Wild and Scenic Rivers System.

American Indians

True pioneers along the Mnisose Wakpa (turbulent river) were the American Indians for whom the river valley was a highway and a home. It provided shelter, wild game, and garden plots of fertile soil. The "Great Circle" of life along the river followed seasonal patterns. Each season the river renewed the resources that supported those who lived here. Spring brought floods that fertilized the fields. Fruits, berries, and other wild plants became available in season. Migrating birds, spawning fish, roaming bison, and animals wintering along the river dictated the direction of the hunt. American Indians used fire to shape the river landscape. Fire stimulated the growth of new grass, attracting bison and other animals, and kept the land free of trees. When Europeans arrived here, they found a wild but human-touched landscape.

At the time of the first European contact in the late 1700s and early 1800s, the Siouan Ponca were living on the Niobrara River to the west. It is probable that the territory was also visited by Oto, Omaha, and Pawnee. Yankton Sioux were living on the north bank of the Missouri River.

Original Highway West

Spanish explorers in long, flat-bottomed boats (bateaux), followed by French and British fur traders, were the first Europeans to enter the Missouri basin. Americans followed in keelboats, then by steamboats, as the river formed the most practical route to the Great Plains. But the river exacted a price. Artist George Catlin observed that the snags and rafts made of huge trees on the "River of Sticks" presented "the most frightful and discouraging prospect for the adventurous voyageur." Snags, fire, and ice continued to devour boats until the end of the 1800s. The bends were the most dangerous, for here the snags accumulated.

Steamboat traffic largely disappeared after a devastating flood in March 1881. Towns appeared first on the Nebraska side, but only after the 1859 treaty with the Yankton Sioux did communities spring up in Dakota Territory. The 1862 Homestead Act encouraged settlement in both territories. The promise of 160 acres attracted Americans from the East and Europeans from abroad. Many settlers farmed in the river's rich bottomlands, although one wit commented that these farmers never knew whether they would harvest corn or catfish. Descendants of these Czech, German, and Finnish immigrants maintain a rich heritage today.

Restoring the Past

Today everyone and everything here has a stake in the Missouri River, and sorting things out can be a challenge. No single agency can decide alone how to preserve this important riverway. Federal, state, and local governments, tribal agencies, private landowners, and the people who depend on the river for jobs and recreation are working together to find ways to protect the river. Stewardship—saving the river and its natural and cultural resources for future generations—is critical for the river to retain its natural state.

Things To See and Do

Missouri National Recreational River comprises two free-flowing reaches of the Missouri River separated by Lewis and Clark Lake. The 39- and 59-mile districts lie on either side of the 98th Meridian—the eastern border of the Great Plains.

Heading west, Lewis and Clark noticed a change in the landscape: the woods receded, tailed off into tall grass prairie, then gave way to the short grass of the drier high plains. The abundant rainfall and large forested areas east of this north-south line of longitude are missing to the west. This change is increasingly noticeable west of the Niobrara River.

39-Mile District The western portion (Fort Randall Dam to Running Water, SD) has one of the best natural landscapes associated with the river along its entire course, including forested chalkstone bluffs and rolling hills.

59-Mile District The eastern portion (Gavins Point Dam to Ponca, NE) exhibits the river's historic, dynamic character in its islands, shallow bars, chutes, and snags.

Throughout the 39- and 59-mile districts, hiking and wildlife observation are available, including at Fort Randall Historic Site, Gavins Point National Fish Hatchery and Aquarium, Green Island, Bow Creek Recreation Area, Clay County Park, Mulberry Bend Overlook, and Spirit Mound. Hike, bike, or drive along scenic trails and byways at Lewis and Clark National Historic Trail, Native American Trail, Oyate Trail, Outlaw Trail, and Shannon Trail.

Fishing and Hunting Walleye, bluegill, catfish, paddlefish, largemouth bass, and smallmouth bass are popular catches. In season hunters take geese, ducks, turkeys, pheasants, and deer. Licenses required.
