History
People have lived along the river for some 10,000 years. Archeologists have found their tools and weapons, homes, foods, religious, and ceremonial objects. The River is one of three historic east-west corridors, similar to the

of 1862 encouraged immigration into the region. By the late 19th century steamboats plied the river.
During Steamboat Era, the Missouri was characterized by shifting channel, numerous braided channels, chutes, sloughs, islands, sandbars, and backwater areas. Well over 200 steamboats have sunk in the river between 1819 to 1897.
By the mid-20th century, extensive flooding prompted the passage of many flood control measures. The Flood Control Act of 1944, (the Pick-Sloan Plan) created the Fort Randall and Gavins Point dams.
Flora and fauna

. The annual floods create a variation of floodplain vegetation and succession throughout the park. New deposits such as sandbars and accretions adjacent to the riverbanks are covered with the pioneer species: annual weeds, short-lived grasses, sedges, and seedling willow and cottonwood. On higher above the water table, larger willow and cottonwood trees dominate. The floodplain forest includes larger cottonwoods on the highest banks and islands. The understory in the cottonwood forest is primarily dogwood, sumac, wild grape, and poison ivy. The sparse vegetation under the mature cottonwoods consists mostly of scouring rush, Kentucky bluegrass, smooth brome, and other invasive grasses and weeds.
Above the floodplain, there is a mixed forest and agricultural fields. The forests on the adjoining bluffs are primarily hardwoods with the slopes covered by a dense growth of oak, ash, mulberry, and walnut, with burr oak as the dominant species.
Wildlife is plentiful. Since the days of Lewis and Clark the larger mammals have disappeared, including the grizzly bear, bison, and elk. Small mammals, including mice, voles, bats, rats, and ground squirrels make up the bulk of the species within the park. Deer are often seen on private property along the banks.
The American Bald Eagle has been gradually increasing throughout the park. Two other birds, the Piping Plover (Northern Great Plains population) and the Least Tern (Interior population), are still listed as threatened and endangered respectively. There are over 250 bird species identified within the riverway.
