Pretty much. Its an intermediate to brackish Marsh plant. Salinities get to high and it will die. I've seen places where salinity was too high for it, especially in 2011. Those same places had it in 2012 after we got all the rain and the system freshened up.

Screw those redfish, the marsh didn't live without the weirs ever before, so why should it now? Let's be sure to keep the saltwater out, because it's never been in there before, and it will kill everything. Who cares about the lake, shrimp, fish, and rest of the ecosystem as long as we have grass. Lol.

What i don't understand is why does that marsh need to be completely fresh? There are plenty of brackish marshes all along the LA coast, just like there has been for thousands of years.

I remember that, you would have never thought there was that many redfish back there until that fish kill.

Have you been to the east side of the state before? All that marsh you talk about is disappearing before our eyes. When I have kids and they are my age there will be no more marsh between leeville and grand isle probably. It has reduced by more than half in my lifetime alone. So while the weirs may not be the best option for all parties, they are better than losing all the marsh and then there is no habitat for all those shrimp and redfish yall are crying about

That is what it all boils down to....they are trying to save land with weirs,not fish and shrimp. Just look at the wax lake outlet....only area in la building land. If the wax was never dug im sure there would not be much land left between the open bay/gulf and morgan city.

Been all over the west side marsh (dang near the tx line.) Only seen 10 or 12 shrimp, in a week. And the water Is salty salty!!!! but on a plus side the marsh and the gators where better for us this year!

Better build a levee and weirs in Sabine lake then too. I'm not crying about fish and shrimp either I don't really care. Man-made canals and channels are the reason the east side of the state is losing land. I understand we have a ship channel that is not natural, but everything works in cycles. Yeah the salinity levels may get high in that marsh at times, and at other times the water will be extremely fresh. Mother nature is better at working things out than we are.

If that is the argument, why aren't there weirs and levees on every coast of every lake in southern LA? It doesn't take a rocket scientist to tell that there is little to no difference in the east bank of Big Lake and the east bank of Sabine Lake.

So i guess it is okay for saltwater intrusion to happen in the marshes west of West Cove?

There's nothing but greys, pintail, teal, and spoonies back there anyway lol. Might as well be salty they'll still be there. It's not like that marsh is going to turn into lilly pads and cut grass and be covered up in mallards. There has to be more too it than that.

That's what's supposed to be in it anyway. Hypothetically, if tomorrow they decided to fill in the ship channel and put the river back to the way it was decades ago, would you be for it or against it?

Since following this topic and reading the article in the local paper dated 9-7, it appears the salinity levels are increasing with the weirs closed. The article mentioned that the salinity level was 8 ppt and was about to be opened within a week, but then the level shot up to 13 ppt. Now according to this thread the salinity level is 15ppt.

Where is the breach into the marsh? Or do the analyzers need to be calibrated?

Perhaps a diversion project would be a good option to take some of the lower salinity water from the intracoastal waterway in order to blend down the salt water intrusion?

Freshwater lighter than salt
..

Water is low and evaporation happens where?? On surface

That's a stretch. Gotta look at what we have now.

I know that. I'm just wondering what's more important. Catching specks or saving our coast. I know the west side doesn't have that problem like the East does but I'm just curious what the support would be if that could happen.
