Missouri River Valley

The Missouri River Valley outlines the journey of the Missouri River from its headwaters where the Madison, Jefferson and Gallatin Rivers flow together in Montana to its confluence with the Mississippi River in the State of Missouri.

Although 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.

The Loess Hills are a unique geographic feature of the valley.

As temperatures warmed, the glaciers retreated and vast amounts of meltwater and sediment flooded the Missouri River Valley.

The first recorded event is the Great Flood of 1844, which crested in Kansas City on July 16, 1844, discharged 625000 cuft per second.

The Chouteau family operated under Spanish license at St. Louis in the lower Missouri Valley as early as 1765 and in 1821 the Chouteaus reached Kansas City, where François Chouteau established Chouteau's Landing.

At 2300 mi long the valley drains one-sixth of the United States, and is the longest river valley on the North American continent.

Loess, a wind-deposited soil, is compounded in slowly rising hills at various points in extreme eastern portions of Nebraska and Kansas along the Missouri River Valley, particularly near the Nebraska cities of Brownville, Rulo, Plattsmouth, Fort Calhoun, and Ponca, rising no more than 200 ft above the Missouri River bottoms.

Brownville sits in the Loess Hills above the Missouri River Valley.

They are the Fort Peck Dam in Montana, the Garrison Dam in North Dakota, the Oahe, Big Bend, and Fort Randall Dams in South Dakota, and the Gavins Point Dam in Nebraska and South Dakota.

The hydroelectric plant generates 493,300 kilowatts of electricity at maximum capacity, with an annual production of 969 million kilowatt hours, and meets peak-hour demand for power within the Missouri River Basin.

The Flood Control Act of 1944 introduced the Pick-Sloan Missouri Basin Program.

Several water-control measures were introduced through the Pick-Sloan Legislation that variously affected the Missouri River Valley and its environs.

They are the Fort Peck Dam in Montana, the Garrison Dam in North Dakota, the Oahe, Big Bend, and Fort Randall Dams in South Dakota, and the Gavins Point Dam in Nebraska and South Dakota.

Pick-Sloan Program Dams to assist with conservation, control, and use of water resources in the Missouri River Basin.
