And if Morganza is not opening why not divert more flow into the Atchfalaya R. then kicking more into the Teche-Vermilion diversion during high waters?

Wasn’t there a project the State was supposed to start working several years back called Mississippi Reintroduction into Bayou Lafourche?

This is a photograph of the wood chips that were recovered from 123 feet to 154'. They are very light and the strands are very flexible.

This is a photograph of the sand that was recovered from 154' to 185'. We were expecting to hit this at about 125 feet like we did in the other close by wells. There was a cleaner sand below this to 217 feet.

This is the e-log of the well. It shows overburden to about 130, the wood from 130 to about 158 and sand to 217. Below 217 is a break point of clay/silt that separates the Chicot Aquifer above from the Evangeline Aquifer below. I did some test wells south of this location and found the Evangeline Aquifer to be brackish so we were not interested in exploring any deeper.

Fascinating photos. Given enough time could that sand form sandstone. I’m totally uneducated in geology except for a few paragraphs in other disciplines.

Not familiar with much below the Chicot and Evangeline aquifers as I am interested in finding drinking water. I would not doubt it though, as both aquifers get deeper and somewhat thicker as they progress south. The Evangeline Aquifer is brackish north of Lafayette and is flat out salty the closer you get to the Gulf of Mexico. Likewise for the Chicot but it gets Brackish near Abbeville and further south. The Chicot Aquifer really gets messed up around salt domes though. Very irregular water quality. I guess due to the eruption of the dome.

The Chicot aquifer runs all the way to the GOM, right? About what depths are we talking about for this Aquifer?

Amazing. Could a study determine the type of wood?

(Also, Antarctica is rising at the rate of 1.6 inches a year. Due to ice melt some say.)

Back on topic: For a tree to survive the decaying process, whether upright or in a water rush current heap. Don't you think some sort of sediment protection would be involved. Probably followed by immense pressure.

I can't see tree matter surviving (not decaying) in ether manner with a slow sinking process.

Doesn’t decay, rot require oxygen. Probably used up rather quickly.

That would rule out gradual was my Q/prem

This all reminds me of my 7th grade science class: we went outside (on a beautiful spring day) on the football field and had big blue trays of sand and that we could set at different angles. There was a hose at the top of the trays that let us also control the flow of water.

From there we were able to create mini 'rivers' and watch how the courses changed, forming ox-bow rivers etc. I remember realizing that what had happened at False river, where friends had a camp that we'd go skiing and hang out.

It was a great lesson and one that has stuck with me all these years.

We found similar wood chips when the water well folks dug my well at home. I think the chips were found around 150' down. I was amazed to find them. I'm about 200' off the bank of the Vermilion in Vermilion Parish.

That's correct. That is why the Chicot Aquifer is brackish south of Abbevile. The Chicot Aquifer has variable depth and thickness. In some places it is divided into the upper chicot and lower chicot with a clay break between. You can reach a sand as high as 35 feet deep but it is usually not water bearing. It can be almost 500 feet deep and 400 feet thick in some parts. I just completed a well near Loureauville that was almost 500 feet deep with a static water level of 11.0 feet. Almost an Artisian well. It produces a boat load of water.

North of Abbevile I'm thinking or it would be salt water that deep.

I'm on a east/west ridge (24' elevation) between Milton & Youngsville.

That is correct. About 7 or so miles north at Woodlawn.

Done.

Well, here is today's nugget for the global warming crowd to fret about.

Back on topic, I’ve heard that ACoE has notified landowners to remove movable property out of the Morganza Spillway. I haven’t confirmed this, so it may just be rumor at this point but I think with the degradation of the levee up around Blackhawk Plantation they may need to relieve som pressure.

tRump's rollbacks are not helping.

Go to the your favorite APP store and download USACE Vicksburg APP. It will give you access to lots of valuable information. The Mississippi river stages are predicted to drop after the 15th of March at most stations along the lower reaches of the river. It really needs to do this because once snow melt starts it will probably come up again. The app has a link to twitter feed and river stages.
