re: This is Huge For Our Coastal Restoration

Article clearly states this project took place on Pass A Loutre Wildlife Management Area, which is owned by the state.

Sorry. I was referring to mardi gras pass.

Closing Bayou Manchac off to the Mississippi River is what killled it. Maurepas Swamp wouldn't, I imagine, have any impact on Bayou Manchac because it connects the Amite River to the Mississippi. Too bad this bayou cannot be used anymore as a relief valve for when the Amite gets above flood stage.

I meant cutting off Maurepas from the Misssippi ruined Manchac, because that was the connection between the Mississippi and Maurepas.

It may not have been a huge source, but it was a source of freshwater.

If they want to save the current delta, they are going to have blow holes in the levee much farther up towards Belle Chasse.

bingo

Faults have definitely played a role as well. Oil canals and resulting spoil banks have obviously as well. (Disrupting hydrology and whatnot.)

So how much money was spent on doing this????

Another 'stopping' nature project that will eventually be a waste. Same can be said for rebuilding New Orleans.

Posts like this are why I fricking love the internet.

Any a-hole with an incredibly unfounded and poorly researched opinion can pass it off as indisputable fact.

I'll have to hop on my computer to take a look at the article; too large for my phone to handle. However, I was doing some other reading on the faults, and I do recall (fuzzily) reading about this in the past. It makes sense in some areas, but not all. Also, Big Branch is an area in particular that gets muddy to me, because there are canals there that impact erosion.

And while I agree with your point regarding canals/fisheries, it is not a sufficient enough justification for the canals. Saltwater intrusion has caused significant marsh to open water conversion within the Cameron-Creole watershed, which is great for the fisheries...until the marsh is completely gone and it is one giant, open water system. While this was not a direct result of canals, it was caused by man-made alterations, and I can thini of other instances where canals have led to significant erosion.

That being said, I think the canals/trenasses are more significant in the chenier plain as opposed to the deltaic plain. But, with the loose riverine sediments that make up the deltaic plain, it's not difficult to imagine the impact those canals could have on a system. While the studies may show that faults are having a significant impact on wetland loss, they are not as visible as the canals that stretch across the coast, and the ever-expanding open waters they connect to. Just in the Falgout Canal/Dulac area, there are significant areas of open water, with the only land being along the (former) banks of the canals. Whether these canals are acting in conjunction with faults I do not know, but it is hard to argue that those canals didn't have some effect on that marsh, even if it was just allowing saltwater flow into a previously fresh or intermediate marsh, causing vegetation dieoff.

Actually we fricked with nature rerouting the river with levee systems you assclown. Learn how things work. The river used to deposit sediment to create barrier islands and land. We are putting it back to the way God created it to a very small degree. Good grief.
