When I was a teenager at a summer camp in Minnesota, we built a rope bridge across a creek. I asked what creek this was, and the counselor said it is the Mississippi River!

The situation the US finds itself in with the Atchafalaya really invites comparison to the Yellow River in China. The Yellow River has a habit of dramatically changing course every couple hundred years due to its high sediment load, and when that happened it usually caused enough chaos for those who depended on it for irrigation and trade to topple dynasties. The scale of the shift in the river's course is really hard to overstate, in several shifts the mouth of the river moved 200 miles. That's like if the Hudson River suddenly switched to emptying out in Boston instead of New York, or if the Colorado rerouted to empty directly through Los Angeles. While the Mississippi wouldn't move quite as far or plow through quite as many population centers, it would absolutely cripple the ports in New Orleans and Baton Rouge, which handle a massive fraction of the food and goods produced in the central third of the country.

The reason that Louisiana is losing land is NOT because of rising sea levels. Sea levels are rising but it's on the scale of centimeters millimeters per lifetime. It's not something you can see. Louisiana is losing land because we no longer allow the Mississippi to flood. Without the renewal of sediment that the yearly floods used to bring most of the delta is sinking.

I grew up in Morgan City, near the Atchafalaya and was always told that it is not IF the Mississippi River overtakes the Atchafalaya, but WHEN. Also, KUDOS on your pronunciation of Atchafalaya.

Living in a city located on the Atchafalaya River, I find this video very informative. For decades we have known that the Mississippi River would naturally search for the path of least resistance on its journey to the Gulf of Mexico. That would be the Atchafalaya. This would wreck Baton Rouge, New Orleans, and the dozens of communities further downstream, not to mention completely re-defining Louisiana. If I remember correctly, at one time the Atchafalaya was one of, if not the deepest river in North America with a very fast current. The spillways and controls to prevent the Mississippi River from diverting its course have been Herculean and done for some very good human reasons. They have also slowed the Atchafalaya down enough to allow rapid sediment build up to the point that you could ALMOST walk across it where I live with sandbars regularly popping up and it must be dredged regularly. Sandbars are pretty regular further downstream and demonstrate the growing delta forming at Atchafalaya Bay. To paraphrase Jeff Goldbloom in the Jurassic Park movies, "Nature always finds a way." When those structures that are keeping the Mississippi River flowing in the direction where it is now flowing=towards Baton Rouge and New Orleans-eventually give out---and one day they will--you have to applaud man's ability to TEMPORARILY keep Mother Nature from doing what she wants to do.

It might have been Shreves other project, the removal of the great logjam in northwest Louisiana,that really causes this. By enabling the Red river to flow much faster it made the Atchafalaya faster and more able to erode a deeper channel.

I was having difficulty understanding how straightening the Mississippi river made it more likely to divert but your video makes it much easier to comprehend.

At 6:29 you show a photo of the current delta, and it shocked me greatly. I grew up hunting and fishing around Lake Salvador and Barataria Bay, and remember that there was MUCH more grassland there south of the river (up in the photo). While you can easily see the sediment blooms from diversion projects, you can tell that it will take some time to restore the delta. We really need several more projects to get as much sediment as we can during periods of high water. PS: I forgot the obligatory "I can see my house in that picture 😊

Interesting... around 7:30, the Red, Atchafalaya and Mississippi kind of forming kind of that 4-way 500 years ago. The same thing can be seen today at another major river's delta - the Mekong. At the city of Phnom Penh which is kind of considered to be the northern-most point of the Mekong delta, the smaller Tonle Sap river meets the Mekong, which then branches and forms the smaller Bassac river which does the exact same thing as the Atchafalaya. Southeastern Cambodia and southern Vietnam have much the same geography as southern Louisiana - very flat and low lying. Sensing a pattern here!

I heard a quite a bit of this story when I was a geophysicist with Shell Canada. I was on a course in clastic sedimentary geology from the legendary Rufus J Leblanc who had been the head of the Mississippi River Commission in the 1940s. I looked him up just now and see he made it to 89 years old. Thanks Rufus for making geology so interesting and leading us scrambling over the rock outcrops when you were in your late 60s.

After all this, you miss that the Mississippi and Ohio Rivers join at a point where the Ohio River is larger, that the Ohio River actually starts in northern Pennsylvania, where it is now called the Allegheny River, and that the St. Croix River is actually larger than the Mississippi river where they meet, except for the artificial constriction of the St. Croix at that point. By naming conventions, which are all violated by the naming of the Mississippi River, the MR ends at St. Paul Minnesota. The St. Croix River flows south from there until it flows into the Ohio River, which actually flows from Northern PA to Western NY, back south through PA, and all the way to the Gulf of Mexico. So, by breaking all the rules, we have one of the smallest rivers in the USA (the Mississippi) being considered the largest, the largest one (Ohio) being cut into three pieces and named Allegheny, Ohio, and Mississippi, and the St.Croix River essentially being ignored despite being a very long river.

Thanks Carter for discussing my home state! I learned this stuff in Louisiana history class in middle school. Part of my family grew up on an oxbow lake called False River, near Baton Rouge.

In 1973 the flooding almost succeeded in going down the Atchafayla river thru Morgan City.

Atchafalaya is simply part of the delta. Mother nature does not care where man draws lines and boundaries. She's gonna do her thing, and we don't have a chance in heck of stopping her.

Well now you may need to do a video about The Great Raft. It’s my understanding that after Shreve had the Raft broken up the Red River was no longer navigable above by steamboat as far north as it was prior to the breaking. People seem to have a hard time understanding just how large an area it covered.

If nature were allowed to take its course, the Mississippi River would already flow down the Atchafalaya or more likely where the Morganza Spillway is now dammed up.

Somebody finally talks about the Atchafalaya basin. Prolly one of the best fishing spots in Louisiana if you have a boat

Good video, I think the Army Corps of Engineer’s efforts to reroute the rivers had just as much if not more to do with the current situation than Captain Shreve did though.
