At the headwaters of the river, the water moves at an average speed of 1.2 miles per hour, although it speeds up to about 3 miles per hour by the time it gets to New Orleans. The surrounding watershed is the world's fourth largest, stretching from the Rocky Mountains to the Allegheny Mountains, including parts or all of two Canadian provinces and 31 states.
