Mississippi River Facts
Excerpts from the Mississippi National River and Recreation Area:

Length - River length is a difficult measurement to pin down because the river channel is constantly changing. For example, staff at Itasca State Park, the Mississippi's headwaters, say the Mississippi is 2,552 miles long. The US Geologic Survey has published a number of 2,300 miles (3,705 kilometers), the EPA says it is 2,320 miles long, and the Mississippi National River and Recreation Area maintains its length at 2,350 miles

Width - At Lake Itasca, the river is between 20-30 feet wide, the narrowest stretch for its entire length.
The Mississippi is more than four miles wide at Lake Onalaska. Near LaCrosse, Wisconsin, Mississippi water held behind Lock and Dam #7 and water held back by damming the Black River combine to form this broad reach of the Mississippi River.

Depth - At its headwaters, the Mississippi is less than 3 feet deep. The river's deepest section is between Governor Nicholls Wharf and Algiers Point in New Orleans where it is 200 feet deep. x

Volume: At Lake Itasca, the average flow rate is 6 cubic feet per second. At Upper St. Anthony's Falls, the northernmost Lock and Dam, the average flow rate is 12,000 cubic ft/second. At New Orleans, the average flow rate is 600,000 cubic feet per second.

Elevation: The elevation of the Mississippi at Lake Itasca is 1,475 feet above sea level. It drops to 0 feet above sea level at the Gulf of Mexico. More than half of that drop in elevation occurs within the state of Minnesota.
