The Mississippi River is one of the world's major river systems in size, habitat diversity and biological productivity. It is also one of the world's most important commercial waterways and one of North America's great migration routes for both birds and fishes.
Barges and their tows move approximately 175 million tons of freight each year on the upper Mississippi through a system of 29 locks and dams.
