Miss. River Water Level Questions
Posted on 5/11/20 at 9:54 am
Posted on 5/11/20 at 9:54 am
Guys in all seriousness! Why does the Army Corps of Engineers allow the Mississippi River to stay at this height for so long? The amount of Habitat and hunting areas this high levels of water damages is crazy. As well as farming. What are the true politics behind keeping the water level this high?
Everything is backed up and flooded. Went over the Tensas, never seen it this high for so long. Then went over the Miss River in Natchez,,, unreal how high for so long?
Why do they allow this and then open the Bonnet Carrie to dump all the fresh water into Lake Ponchatrain?
Is it really because of all the High Dollar Hunting clubs in the Spillway area?
Any logical reasoning to keep it this high?

Lucky for you its falling pretty good right now.

Correct me if I’m wrong, but I believe the lock structures are to relieve pressure on levees south of the lock structures. There are no controls to “lower” the river levels north of locks

The corps has flow rate levels that trigger openings of the lock system in stages. Those other issues you mentioned earlier don’t factor into it on the surface (but are discussed at a higher leVel than you or I). With all that being said I was in Concordia this past week and I can tell you the length of time that the river has stayed well above flood stage for the past 4-5 years is really taking a toll on the levee system. There are levee washouts in numerous places including one near the Morganza spillway. Thankfully the levee is really wide in that location. I know they are really concerned about uplift on the land side of the levees as well. The Corps is going to have its work cut out for it when the water goes down to get all the repairs in before next years high water.

I have three projects that have been held up since February because we can't do about three days worth of underground utility connections. Finally looks like we are going to drop below 15 feet in New Orleans next week.

inasmuch as I live about three miles from the River, I've been concerned about this for a while. I don't see the ACOE doing a whole bunch of work around us but I know I've seen some good boils in years past. I sure hope they know what they are doing.

The Corps ordered up another wet spring. The Corps gets what the Corps wants. Will Morris Bart file a lawsuit against Mother Nature? God? Trump?

The system is designed to protect the large cities. They don’t open anything unless there’s a downriver threat to a large city. As soon as the threat passes, due to water levels decreasing, they close up the structure.
The entire System Is one of the best return on investments the government has ever designed. It’s certainly been tested in recent years, but it’ still works even after all these years.

US COE has no control over how much water comes down the Mississippi.
The levees they built to protect populated areas from flooding keep the river in its channel and allow higher water level. If there were no levees the river would be spilled over its natural banks and covering half of southern LA right now. The levees and rising river bed elevation do allow the river height to build up quite high, as designed.

Guessing you slept through spring last year it was a lot worse for longer.

I don’t think they are doing it on purpose they have guidelines to follow. I was told the river is so silted in that the flow rate would never be reached to trigger the opening of some of the spillways. The river is staying high due to it not being dredged like it use to be. I was told that in 2008 Obama cut funding for dredging the river. They said there use to be three dredge boats in the river in New Orleans and now there’s just one, not sure if that is true. They are supposed to start a dredging project from the mouth to Baton Rouge. Here’s a few links about it. Dredging Today and NOLA.com

Because not ruining oyster beds and saltwater fishing is more important than some hunting land.

Supposedly a major part of of the restriction is right downstream of Morganza.

I don’t doubt it. The person we were talking to said that the river would over top the levee before the triggers to open the spillway was reached because the river was so shallow now. They really need to do something. I’ve been trying to build a house on river road and it’s been one thing after another with the Corp of Engineers. I finally got a waiver to start when the river reaches 15’ in NOLA. But that’s only to do the slab as I can only dig 1’ into virgin soil till it hits the 11’ mark.

2020, the year of Covid, Government boot to the throat, negative oil and when the MS river said frick yalls levees.
Seriously though it look like we made it through this spring without much flooding compared to the previous couple.

There are flow triggers and elevations triggers to open the spillways. Elevation triggers I don't believe are published. They cant let it over top major levees downstream simply because the flow trigger wasn't met. Your friend is correct, siltation is the issue. Higher elevations are being seen with lower flows. I don't know if it was Obama specifically, but dredging funding was cut. Mainly passed New Orleans though which is not causing the problems upstream. South pass for one is no longer dredged.

Would take every dredge in the country working round the clock to have an impact if any on overall river bed level.... it was a good run for the Corp and man made structures but it is only a matter of when not if the river does it’s thing. May not be our lifetime but who knows.

Uh, because the river has flooded nearly every year for thousands of years and it's just part of the water cycle.
