That said yes ike and reida did a bad number on the marsh in sw la.!! See it first hand.
But why on the west side if BL. ( way more lose then the east side of BL. It is finely coming back and regrowing??
The 4 sets of wiers on that side have not been closed in 10 year's I know of. And none of the concrete/board wiers in the marsh ( you take out and put back for boat passage) even have the boards in them. And that marsh is starting to come back.
As far as the channel gos open all flood gates and dames and let it flood and wash sediment down and the marsh will rebuild way faster.
But know they stop/dame it up to protect people that chose to build on a river that floods!!!
Reida nocked down the levee on the east side of BL. For a reason??? What reason I don't know!!
Sorry for all the spelling erears in a tractor, feeding yalls families!!!

We already figured that out as well. Pretty sure one of the mods said your house was not underwater, so no swimming for you
Marshes are typically organic soils (muck), sediment is needed to build the foundation. If you put sediment on top of a muck marsh its no good. The plants are what keep all that held together. When a freshwater, intermediate, or brackish marsh is exposed to saltwater for long periods of time the vegetation dies and the soil washes away because there are no roots to hold it altogether. Salt marsh would handle that fine, but thats not salt marsh. Salt marsh couldn't come in because there would be no soil left for it to establish. (thats a very very condensed version, much much more to it than that).
Take home lesson: saltwater bad for plants that are not adapted to saltwater, pour a bucket of saltwater in your garden and see what happens. Salts are used for defoliants in farming industry to defoliate plants (kill them) so they can harvest. Salt was also used in the ancient times when peoples? would defeat another peoples?. They would 'salt the earth' so that nothing would grow and they would have to move on to find other areas to farm to feed themselves
