Key Points:

  • The Mississippi River Watershed is the 4th largest in the world with water from 31 states and two Canadian provinces feeding into it.
  • The deepest point of the Mississippi River is 200 feet deep in New Orleans, Louisiana, where it empties into the Gulf of Mexico.
  • 92% of the nation’s agriculture exports are from the Mississippi Watershed area.

The Mississippi River flows from Minnesota down to Louisiana, emptying into the Gulf of Mexico. But just how big is the Mississippi River? Watch this video to get a glimpse of the massive network of rivers that feed into the Mississippi and finally end up in the Gulf.

The video starts where the Mississippi River starts, Lake Itasca, MN. Did you know that the Mississippi travels about 2,350 miles? The widest part of the Mississippi River is 11 miles wide at Lake Winnibigoshish near Bena, MN. The deepest part is 200 feet deep in New Orleans. When it reaches the Delta and the Gulf of Mexico it discharges at a rate between 200,000 and 700,000 cubic feet per second!

It passes through 10 states including Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi and Louisiana. The video shows a map of the US with the River’s journey highlighted in blue.

There are three major rivers that flow into the Mississippi. To the NW is the Missouri River which starts in Montana and is just slightly longer than the Mississippi itself! Then there is the Arkansas River which starts in Rocky Mountains near Leadville Colorado. It flows into the Mississippi in Arkansas. Lastly, the Ohio River, which actually starts in Pittsburgh, Pennsylvania, but flows along the southern border of Ohio down to Cairo, Illinois where it joins the Mississippi.

Next the video explains how tens of smaller rivers and streams flow into all of these rivers. Basically, all of the waterways are highlighted in blue on the map. It explains the drainage system covers 1.24 million sq. miles, the same area as 2 Alaskas!!

Additionally, water from 31 States and 2 Canadian Provinces feed into the drainage system. This makes it the 4th largest watershed in the world. The Amazon Basin, including the Amazon River and all of the rivers and streams that feed into it, is the largest watershed in the world. It covers around 3 million sq. miles!

An aerial view of the Mississippi running through fields is shown as the video shares that 92% of the nation’s agriculture exports are from the Mississippi Watershed area. Next, you see a couple of cows munching on some feed. The statistic of 78% of the world’s export of feed grains comes from this area is posted. Then the aerial view of a large barge floating on the Mississippi precedes that 60% of grain exports are shipped out on the Mississippi.

Lastly, the final image is the map of the US with all of the Mississippi River watershed highlighted in blue so you can see just how massive the connections of rivers and streams is. It closes with the quote, “Without this watershed, the Mississippi River wouldn’t be the resource it is today.”

This long, majestic river is teaming with life in and around it. The Mississippi River provides food and shelter for birds, fish, and many mammals. There are more than 120 species of fish in the Mississippi! These include:

Also, native mussels are making a comeback after being nearly wiped out by pollution. Some species include the Higgen’s eye and winged mapleleaf.

Many migrant birds call the Mississippi River valley home. It is a birdwatcher’s paradise! Check these out:

Mammals take advantage of the river’s habitats, including otters, beavers, coyotes, and white-tailed deer. Once in a while a black bear and mountain lion might stop for a drink. Don’t forget about the beneficial insects, reptiles, and amphibians that reside in this river valley.
