That is a great point and Im sure it has something to do with it. The old river valleys are filled relatively young, unconsolidated material vs terrain that the river never cut through.

There are spots in Johnsons bayou where geologists theorize that the red river & possibly the mississippi used to flow and they cut channels through the chenier where a 60 foot concrete piling will nearly sink itself with its own weight. And a few hundred yards away its a struggle to drive one fully with a diesel hammer.

Amazing terrain in south Louisiana.

It was actually a river much larger than the Mississippi dating back to the end of the ice age, when the shoreline was on the outer continental shelf. The melting glaciers created a massive river that flowed out around where the Sabine River is today. If you look at sand deposits within the underwater terrain of the OCS, you can actually trace parts of the old river bed. The sand from those deposits is the sand they're using to pump in to rebuild beaches.

I have seen boils and they are nothing to panic about. They become dangerous when the water flowing thru them becomes muddy, as long as its clear its ok

Clear water means it's just water seeping through, muddy water means the levee is eroding.

Even that clear water shouldn't make you feel all warm and fuzzy though These boils are going to be a concern for quite some time even with both spillways open.

Clear water means it is flowing through a sand. The sand is porous enough to let it through. Muddy water means it is pushing dirt out in front it it. Clear water is permeating a sand. Muddy water is washing out dirt.

Clear means it has found a path through sands. If you plug the hole, there is no problem.

Clear means there could possibly be a problem.

Muddy means shite is getting real.

Makes you wonder how many of these go unnoticed on the thousands of miles of MS river levee

Sorry to have been away from the computer and unable to respond to smart arse comments, but I went over to the sheriff's office and they were not aware of anything unusual - meaning no word of any sort of immediate danger - around Morganza. There are a lot of people here who in Pointe Coupee who are very concerned about the levee conditions. A statement about a major boil is something taken very seriously and any reassurance that people near the levee are not getting ready to drown is normally welcome. So, no, my brother is not Stevie Wonder. He grew up here and knows what a boil looks like. When he said he saw nothing unusual, he meant that he saw nothing to think that there was any sort of imminent danger.
