The Mississippi is predicted to crest at 51.5' on the 15 March. I heard yesterday the snow pack is above average in the northern states. Currently the snow pack is not as high as 2011 levels. The backwater area is extremely high as well. We need a month with no rain.

I thought I heard they were opening the Bonnet Carre spillway today or tomorrow. I know that doesn't help us much, but its the first time its ever been opened 2 consecutive years since its existence.

Yep, and they are watching for Morganza and have barges loaded for Birds Point - New Madrid. It will be an interesting next couple weeks.

Yes it has just been rebuilt. It hasn't been approved to activate the floodway yet. Due to logistical challenges from the last time the decision has been made to mobilize the crew for now.

I’ve been around a lot of conversations in the last few years concerning the big muddy. It seems to bring out the best in ppl.

Has the Corp ever dredged it? What yr did that stop?

I honestly keep hearing about silt so I’m curious as no one has ever answered that question.

It seems like there’s a lot to contribute to the bottle necking. Every year for the last 7 it seems we experience a flood. More pavement, better drained lands (taken low floodable ground and land formed it), and nothing has really been done about the main drain! Maintaining our infrastructure sure has seemed to go to the side. I know we experienced a ton of rain and all. But it seems what used to do ain’t working in today’s environment. Not starting an argument or anything, just the way I see it.

Mm, I'm sorry I didnt address your question. I took off on a nostalgic trip into yesteryear. ...
Something about high water makes me want to talk about the $#!+ I've seen over 56 years of delta life....
I'm not a hydrogeomorphologist( yes that is such a thing) but have a working knowledge of hydrology and hydralics.
Sediments (sands and silts) can stay suspended in hydraulic flows at or above 2 feet per second velocities( generally speaking. Supposedly the Mighty Miss , although silt laden, can maintain sediments in suspension during in channel flows....Its only when velocities drop due to blockage, widenings, or lateral drainage inflows do you get sediment buildup.( outlet of Ms River at Head of Passes, port facilities adjacent to the Main Ms, spur dikes, etc). Now out of bank/ Overbank flows drop sediment like crazy. Why, surface friction changes(trees and other ground features).
It takes some serious hydraulic modeling to design and install features in channels to either deposit silt or scours silt by jacking with channel geometry or armament(rock checks, toewall dikes, etc)...Think about Achafalya basin, it use to be the recipient of overflow silts( land building) by fanning out the flow and dropping the velocity thereby depositing sediment.....
I'm through typing now.....I'm sorry, you asked me what time it was and I tried to tell you how to build a watch....My apologies, I kicked into engineer mode...

I’m not able to find historical data on backwater/landside flooding levels. Do any of you have that or links to that information? And/or maps of what is under water at what levels (have found some estimates from 2011 on those). Thanks.

The 1973 Leflore County flood map i mentioned was scanned and we put a copy at Cottonlandia Museum in Gwood.
I wish i would have kept the 1991 map we generated but i didnt.

Often, after big historic floods the USACE will generate a post flood report.You can probably find them on their historic data.
They had one in 1973 and 1991 and i remember some Main Ms River reports from 1937, 1997, 2008, and 2011.

I have a snapshot of the 1973 Leflore flood map i can send to someone if they will post it on here (this topic).

MEMA paid a visit to our camp today. Second time someone has launched a boat off 6 mile lake road within sight of the railroad tracks.

First time was last week when we did our best to pull our valuables out of the flood waters.
