re: NOAA says sea levels could rise 2 feet by 2050 in Louisiana.

You know what the biggest threat to sea level rise, land loss, and coastal erosion is in SE Louisanan? Oyster Fisherman.

They’ve blocked all efforts and attempts
To allow annual diversions from the Mississippi River south of NOLA. Without replenishing those sediments, that area of Louisoana is fricked. And so is the fisheries. But by god don’t even think about hurting those oyster beds. Everything is moot until you let the MR replenish the sediments as it always has done (prior to the oyster lobby blocking it).

So are you saying the survey data is showing no appreciable subsidence in the last 8 years?

I think you were responding to me. I’m in restoration so I don’t have any apples to apples comparisons with survey data, job sites are altered and we don’t continuously monitor, once the project is complete I as-built and at that point it’s in the landowner’s hands. The only apples to apples comparisons I have is water level shots through the years. I’ve covered the entire Louisiana coastline. Topography and winds alter water levels in different areas, but I’ve worked many projects evenly along the coast and know typical water levels accordingly. The only projects we revisit are ones that promote accretion, and that’s completely localized.

Are we still losing a football field an hour these days.. As long as they've been saying that, seems like Louisiana would be gone by now..

Yep I’ve been hearing that one since at
Least the early 80s. Yet, Theriot, Montegut, Chauvin are all still there. Hurting from Ida, but still there.

You’re a /\.
They have been saying we will be shrimping in the lake for 40 years. The water is not rising. The land is eroding and making the water shallower. The only salvation is 24 hr dredges making a “dispensable”line along the coast line. This is temporary until when, not if, the river changes course. Eventually Louisiana will have to rip the band aid off and see how bad the festering is underneath.

1905 .... Corps of engineers close bayou at donaldsonville shutting off 18% of river flow down Lafourche bayou. Within 5 years, sugar cane processors in raceland notice the salt intrusion

1950. ... Corps of engineers start a nation wide surface soil runoff protection program that in 10 years reduces the amount of silt in the river by 30 percent.



These two actions are well documented in the historical data. The loss of fresh water and silt is the cause of subsidence. Your gov't did this to you

Same morons saying the same crap they've been saying for years. They are full of shite. Scientists don't believe that.

Doesn’t wetland loss have more to do with the Mississippi River being redirected to New Orleans vs. the way it wants to go?

---

Well yes, but they sure as hell aren't throwing their hands up and let the Mississippi River change course. The Mid-Barataria and Mid-Breton Diversions are HUGE for the effort to stave off land loss. But Billy Nungesser opposes them because it affects people's (fishermen's) "way of life."

You're right, Billy. Can't have saving the delta on which our lives and economy is built interfering with Bubba's shitty way of life.

But not in Texas, Mississippi, Alabama and Florida?

What a geographical oddity.
