re: Old man river on the rise

(no message)

I wonder how many decades it will take the corps to study the River from Memphis down and decide it's silting in and dredge it out to New orleans to give the river some free board again.

The river constantly at or around flood stage is insane and just not good for the levee system long term. The cost to dredge would be cheaper than when the levees begin to fail and the lawsuits that will follow.

Just a heads up. One of my nephews smoked the catfish on trot lines on Old River.

Probably so but it damn sure will not be cheap, issue #1 is where to put the spoil and how to get it there.

I am just a guy with an opinion but keeping the river as low as possible during low water by opening the flood control structures may acomplish far more than a fleet of dredges. This will force the turbulance closer to the sediment and let it do the work by erosion but that will cause river traffic issues so

Extended forecasts show it falling towards the end of the month.

Put it on barges Float it down the river and build some land with it

Sounds good brother but I dont believe every barge on earth working around the clock could make a dent in the trillions of cubic feet needed to be moved.

ETA: I went and looked to make sure I was not OTT on the trillions of cubic feet and it looks like I was far underestimating it.

The sediment buildup – estimated at some 36 million metric tons – increases the possibility that a future “mega flood” could overwhelm the structures, triggering a full capture of the flow by the Atchafalaya, with dire consequences for Louisiana’s people and economy, the study warns.

In addition to the bottom sediment, Xu identified some 530 million metric tons of sand on emerged river bars upstream between Old River and Vicksburg. If those were to be mobilized and swept downstream by a flood, they would impede the flow even more and potentially trigger the river to jump its bank around Old River.

Dredging in Louisiana is usually typified by not having good material to build land with. Almost everywhere else the problem is where to put it. We’ll face that same issue that far up in the river.

I wonder what the quality of the sediment is? Mostly sand isn't going to very desirable to dump somewhere.

My daughter and SIL own a bunch of land in between the levee and the river. They sell a shite load of river sand a year. Every time the river rises, it fills back in.
