Mississippi River

The Mississippi River is the second longest river system in the United States. Only the Missouri River is longer. The Mississippi flows 2,340 miles (3,766 kilometers) from its source in northwestern Minnesota to its mouth in the Gulf of Mexico.
The word, Mississippi probably comes from a combination of Chippewa words (mici and zibi) meaning "great river" or "great water." It was first written as "Michi Sepe" by Lieutenant Henri de Tonti traveling with the explorer La Salle.

The Mississippi and its tributaries drain almost all the plains between the Appalachian Mountains and the Rocky Mountains. Its drainage basin is the third largest in the world, exceeded in size only by the watersheds of the Amazon and Congo Rivers. The drainage basin covers 1,247,300 square miles (3,230,490 square kilometers) in 31 states and 2 Canadian provinces. This area encompasses the nation's most productive agricultural and industrial regions. The Mississippi is the nation's chief navigable water route. Barges and towboats on the Mississippi River System carry sixty percent of the agricultural goods, industrial products, and raw materials transported on inland waterways
