The Mississippi River is one of the most iconic rivers in the United States. It flows through 10 US states and is the largest river system in North America, draining an area of 3.2 million square kilometers. Much of the river’s flow is supplied by its numerous tributaries, rivers and creeks that merge into the Mississippi River. The longest tributary of the Mississippi River is the Missouri River. It is more than 3,000 miles long, making it the longest of the Mississippi’s numerous tributaries.<\/p>\n

The Missouri River originates in the Rocky Mountains in southwestern Montana and flows eastward, eventually joining the Mississippi at St. Louis, Missouri. Along its 3,000-mile journey, it winds through North and South Dakota, Iowa, Nebraska, and Kansas before entering Missouri. Along its course, the Missouri River forms the boundary between Nebraska and Iowa and Missouri and Kansas. It also supports many communities along its bank. These include St. Louis, Kansas City, Sioux City, Omaha, and Bismarck, as well as many rural communities scattered along its path.<\/p>\n

As a major water source, the Missouri River is significant both economically and ecologically. The Missouri River provides drinking water, irrigation, and energy to millions of people, particularly downstream in cities like St. Louis, Omaha and Kansas City. The river also links isolated communities to the greater Mississippi River Valley, which opens up valuable transportation opportunities. Furthermore, the Missouri River’s numerous wetlands act as important nurseries for fish and other aquatic life, providing essential refuge for species like sturgeon and paddlefish.<\/p>\n

Despite its importance, the Missouri River has been subjected to numerous human disturbances. Its main stem was dammed in the 1950s, causing much of its native habitat to be cut off from the river’s flow. The presence of invasive species also continues to put significant stress on the river’s native wildlife. In addition, people continue to divert portions of the river to serve commercial and agricultural interests, significantly reducing the flow of the river and destabilizing its fragile ecosystems.<\/p>\n
