re: Planned freshwater diversions will doom LA salt fishing

Deege, I could be wrong, but it looks like you are confused about the purpose of the plan. I can tell you it isn't about the population of speckled trout. It's about saving the coast. If the speckled trout population is first and foremost in your mind, than you probably need to side with Lane and Ricks. If saving the coast is first and foremost in your mind, you probably need to side with the Coastal Master Plan.
Fishhead is a great saltwater fisheman though, he'll never have trouble catching spcs.

Fishhead, you made a good point about areas around Reggio that used to be freshwater but are now saltwater.
My uncle (in his 80s) was telling me that years ago they used to catch bass in Lake Lery no saltwater fish at all and it changed to catching saltwater fish.

Absolutely. People are amazed that I catch bass along with trout and reds in the area now, but in reality, I SHOULD be catching bass, bream, and catfish. The other day, I caught 9 reds, 12 trout, and 4 bass. Not even trying, really. Threw nothing but top water and didn't start until 1pm. Left the trout biting to paddle back in time to beat the rain. GREAT trip, but I shouldn't be able to do that paddling 500 yds from the road.

Haha, don't know about that, Tiga, but thanks.

What will this map look like after the diversions are in place?
Hopefully back more to what it should look like. The saltwater is intruding more and more, Lake Pontartrain's and Maurepas' salinity rises year after year. There is no reason to be catching redfish in Lake Maurepas or for that matter sting rays in Blind River. All we hear is gripes from people who enjoy spec fishing, what about the bass fishermen who have lost fishing grounds due to the salt water intrusion? No one speaks about them because there aren't bass fishing guides by the droves like there are spec fishing guides.
The plan is to save the coast and yes it will hurt some things here and there, but it's to protect what we hold dear and all it to just wither away like it currently is. The barrier islands are just vanishing without sediment to sustain them. Timbalier is all but gone now and all the DREDGE DON'T DIVERT crew is worried about is the trout moving a little bit further out. Apparently specs must have been out at the Midnight Lumps before we leveed up the river and it just flowed out normally through the bays.

For sure-
"anecdotal data" = oral history (no empirical data) and "fairly reliable" is very subjective...
not scientific in the least-

Salt water is the absolute number one killer of trees around that area.

And people answer by saying it's the hurricane's fault. Of course more saltwater was pushed in with the storms. But these surges are ridiculous anymore. Isaac, BARELY a Cat 1, completely inundated areas like Shell Beach, Hopedale, Reggio, Delacroix, and many other places. Why? I lived in S LA from 1969-1996. I remember many small storms coming in and raising the water level a couple feet, but not 9-12 ft for a baby Cat 1 storm! Why is the surge so high? There's nothing left to knock it down! You exit Bayou Terre Aux Bouefs and look for yourself. It's wide open, baby. Drive down Hwy 23 to Venice and cross the bridge in Empire. What used to be 3 very distinct small bays is now nothing but open water. I'm not THAT old, and even I can remember seeing English, Scofield, and Adams Bay from that bridge years ago. Now? Just water...
IMO, and it's JMO, but the reason for the ridiculous surge is the absence of barrier islands and lush marsh to knock it down a notch as it comes onshore.

Also, the geometry of Upper Breton Sound amplifies storm surges, espically those that come directly from the southeast and push water up into the northwest corner...

The water that kills trees further inland around the big lakes mainly comes from the flooding, and then salt water sitting. What these storms do also is erode channels for the now normally more salty water in the lakes to stay in the interior of the swamps and kill the trees. You'd be amazed to see how far inland salt water can affect trees and plants.
Drive on 310 from 61 to I-10. All of those trees are dead or in the process of dying because of salt water intrusion. Drive anywhere south of I-10 from there to Slidell, and you will see the same exact thing. The water gets in there first, sits, channels are eroded, soil eroded, and passages for salt water are opened up.
Would all be minimized had we kept up with the marshes and barrier islands of south LA. Hell, they had been fine for hundreds of years before that

I agree, always has. That's why the area around Bay St Louis/Pass Christian gets 28' surge while other areas get 20' in a Katrina. But, that's a constant. Back in the 70s and 80s, there were minor Tropical Storms and Cat 1 Hurricanes that didn't do anything like what they do now in St Bernard and other coastal LA parishes.

and therin lies most of the problem-
Louisiana's Barrier Islands (and marshes too) have never been permenant landscape features. For instance Ship Shoal was once a barrier island arc simillar to the Chandeleur Islands, which have been degrading naturally and will soon (geologicaly speaking) be a submerged shoal. They used to resemble the Caminada headlands- barrier beaches with attached marshes, which we are witnessing transform into detached barriers...
google the "delta cycle" and you will get some good graphic descriptions of the procession

I've only seen a few trees that could possibly be more than 200yrs old.
If you have a go-devil, you can see some virgin uncut cypress in the top part of Joyce WMA.
To my recollection, that is the only untouched stand of old growth baldcypress in the world. I have seen some random honkers scattered around, but they always have defects in them, and I haven't ever seen more than 1 per acre
It's something awe inspiring for me to see, and one of the most amazing things on the planet IMHO. It's why I love this state, why I love the swamp, and why I love being in the woods. I could sit there for years looking at the things
Guess what's happening to it now. I'll give you a hint....you cook with it and it's not pepper

There use to be a resort on Last Island where people wold vacation. That island is now disappearing also.

Land loss certainly makes surge worse. You can't really rely on hurricane categories as an indicator of storm surge only though. Storm size, track, and duration were all in play for Isaac. The exceptionally long period of time that those Cat 1 winds were blowing in a single direction was a major factor in Isaac's surge, not just the intensity.
You are spot on about the wetland and barrier island loss though. There's nothing to knock it down. Just wanted to point out that there's more to storm surge than wind speed.

Why can't we build commercial barrier islands similiar to the ones they built in Dubai? Not only would it serve as somewhat of a storm barrier, but some revenue could be generated as well. You would have the obvious problems you would have to get around hurricanes, insane insurance, etc. but I'm sure there would be some way to make it work. I guess the ultimate death knell for it would be the environmentalists bitching about where the waste would go.

Yes. Being built in different areas as older delta lobes were transformed to barrier systems then submerged shoals...

Right, they are not being built anymore is the problem we were all alluding to. Marsh isn't either
Posted on 3/28/13 at 2:19 pm to Hammertime
I am well aware of that...
