where do the missouri river and mississippi meet
Missouri River The Missouri River is the longest river in North America.[13] Rising in the Rocky Mountains of western Montana, the Missouri flows east and south for 2,341 miles (3,767 km)[9] before entering the Mississippi River north of St. Louis, Missouri. The river takes drainage from a sparsely populated, semi-arid watershed of more than half a million square miles (1,300,000 km2), which includes parts of ten U.S. states and two Canadian provinces. When combined with the lower Mississippi River, it forms the world's fourth longest river system.[13]
Mississippi River The Mississippi River is the chief river of the second-largest drainage system on the North American continent, second only to the Hudson Bay drainage system.[13][14] The stream is entirely within the United States (although its drainage basin reaches into Canada), its source is in northern Minnesota and it flows generally south for 2,320 miles (3,730Â km)[14] to the Mississippi River Delta in the Gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 31 U.S. states and two Canadian provinces between the Rocky and Appalachian Mountains. The Mississippi ranks as the fourth-longest and fifteenth-largest river in the world by discharge. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana.[15][16]
