Are there really people that live there full time? First thought, it is or at least should not be allowed, being it is a floodway and all. Second? are you trying to make me feel bad for people that we stupid enough to setup permanent residence in a floodway? Next are you going to try and make me feel bad for people that moved to Canada and get cold in the winter?

You've come across as kinda condescending in this thread some times but I 100% agree with you here. LIVING in a FLOODWAY should only be allowed if you sign a waiver absolving FEMA from any and all flood damage to your residence.

If the great flood of 1927 did not change the route of the MS River, why would a failure of the control system today cause it to change route?

Due to a bigger, wider Atchafalaya river?

I read this today:
A more serious problem would be the effect a smaller Mississippi River would have on Baton Rouge, New Orleans, and the ecosystem. Because the river’s current would be greatly reduced, the Gulf’s saltwater would intrude far upstream, killing the vegetation along the river bank and causing soil erosion. Eventually, the river below Baton Rouge would widen to become a giant saltwater estuary.

How would the MS River become wider? There are levees that will determine the width and the flow will be less. Would the Gulf really back fill?

Sounds like a bunch of OT’s are understanding the whole situation at ORCS. I think. Somebody said they hope they don’t live to see it. If it happens in the next 30 years or so I damn sure want to see it. I’m 61.

I believe the Atchafalaya is much deeper now.

Cajuns have been living in that area since mid 18th century. This isn't the first time they've flooded or will flood and frankly I've not heard much complaining about it. As I said they know the drill. It's not land owned by the government-majority is privately owned.

Plenty of people in this world live in places like that and just take the weather as it comes. These aren't people that will be looking for a handout. They will roll up the rugs, raise what they can and leave and when they come back they will shovel mud out, clean up and resume living.

You seem to be enjoying the burden they carry.

. Salt water intrusion will kill the vegatation on the batture. The banks will erode to the levees.

Atchafalya is 3 times as steep and much deeper than the current river tract (shorter, too). Water will take the path of least resistance.

It's facinating reading. Sounds like the river almost changed course in 1973, but the structure held (barely).

GTFO with this crap. They screamed to high heaven last time they flooded Morganza. I Do like how you painted the picture of these being just good ole cajun's living their little ole lives. The Land that was government owned was sold for pennies on the dollar because its planned floodway. And the and that wasnt government owned, the owners got a handsome settlement when the floodway was built.

keep painting that perdy picture. And i absolutely enjoy that burden they carry. It was hilarious looking at these same people you are talkin about, bitching on the news and facebook the last time morganza was flooded. Saying how they couldnt believe the government was going to flood their lands and camp, wondering who was going to compensate them.

From what I hear they have crop insurance and they got paid last time and will get paid again this time

The flooded areas currently building on the Missouri River are more substantial than they’ve had before. It’s all heading this way eventually.

If you guys want to look upstream, check out the “mr340 “ Facebook page. It’s usually about a 340 mile kayak race that takes place on the Missouri River, but it’s mostly flood talk/ conditions and pictures these days.

Not unless they plant a certain percentage of their land. What about the people in the MS delta who never had a shot this year to plant?

Checking out the River forecasts upstream

Natchez
Natchez(6/9 crest) - 2nd highest level on record, but predicted, so far, 3' lower then 2011 flood

Red River Landing
Red River Landing(6/3 crest) - 3rd highest level on record - 1.3' lower then 2011 flood

Baton Rouge
Baton Rouge(6/5 crest) - 5th/6th highest level on record - 0.5' lower then 2011 flood

This is all based on current 48 hour rain forecasts. hoping those forecasts are lower then expected and we get a break for the next few week in the Red River/Arkansas river/lower mississippi water sheds

The atchafalaya riverbed is a lot deeper now than it was in 1927 due to scouring from sending more water down it.

Also the Mississippi riverbed is a lot higher than it was in 1927 due to sedimentation from the levees preventing flooding and deposition of sediment outside of the riverbanks.

The Mississippi riverbed at NOLA is well below sea level. Salt water will enter the body of water from the mouth as if it was a coastal bay, if the flow is slow enough. The only thing that keeps saltwater out now is the high rate of flow.

The current crests show everything will be just fine, based on past historical crest levels. Or so we hope.

Will the Oklahoma Red River levels play into any of this later on after the listed crest dates?

Will this time around, with lower crest levels, play out longer, causing a different outcome?

Yes but the levees will prevent the water being any wider than what the distance between the levees are. Right?

Will Burt find out about Mary’s affair?

Will Jody tell everyone about his new boyfriend?

And will Billy ever escape the cult?

All that and more on this episode of SOAP!

Yes.

It would be come wider than it's current path, not necessarily wider than the levees. Saltwater would kill vegetation, increasing erosion. Also, the riverbed would rise due to sediment falling out instead of being washed downstream. A shallower river would take less water to widen.

There are periods where the river height in Baton Rouge as less than 1 foot above sea level, so yes, the GOM would easily back fill up to those areas.

ETA - It could become wider over time as the levees wear down. A tidal estuary would move lots of land over time.
