No weir system on the east bank of Sabine, and those marshes look healthy to me. Shrimp all over that estuary right now, and you can ask any shrimper calcasieu is dried out. Any correlation maybe/maybe not.

The ship channel is the entire problem for saltwater intrusion. A straight north to south route is the easiest route for saltwater intrusion. The weirs were put in place to mitigate for this. The marshes to the west have not recovered from Rita, I mentioned that earlier and you can look at Google Earth and switch frames from year to year and see this. The shrimp are plentiful because they feed upon decaying vegetation and there isn't a shortage of that in Louisiana and will not be for the forseeable future
