No, weirs WERE needed and this change took time, once the weirs were placed in, the damage had already began.

Again, its not an overnight process, its slow, but not really in geological terms, a hundred years is the blink of an eye in geological terms. You are answering your own questions. The land begins to erode due to wave action, saltwater intrusion kills the vegetation that holds the land together, the land becomes mud, the erosion washes away the mud into the ship channel, gets dredged, repeat. When man interferes with hydrology, the water body tries to correct itself. Look at any pass out into the gulf, one side of the jetties will be shallow and the other side will be highly eroded, and you just keep adding rocks to reduce the problem but the problem will always be there. Rocks and dredging are a temporary fix to a permanent problem

I guess if you can get "UU" to support your rocks and prove that its not going to affect the fishery. But you'd better rock armor all the way up past turners because salt water is still going to get in the lake. You also have to get army corp of engineers on board with that. Good luck on that endeavor.

Hydrology is not my specialty, but my understanding is that rocks prevent erosion from wave action rather than salt intrusion. If the tidal ranges of high and low are not significantly reduced by the rocks, they will do nothing to reduce salt intrusion, because salt intrusion is governed by the volume of flow in (with salty water) and out (with fresh water).

Well its not always such a drastic difference in water levels but it can work both ways. You need to quit being such a whining little man child about this. It's there for a reason and sorry to say its not targeted at ticking you off.

Hey I'm telling facts here...you take a pic for me when the lake side is lower or same level as marsh with gates closed
Please be the 1st to provide us with that pic Mr. Sup up marsh guy

It's irrelevant what anyone thinks about how the weirs should he managed and whether fish slats work or not or how high the water is on one side versuses another. Science, sound scientific knowledge that anyone could see if they know anything of marsh vegetation and succession, drives how those weirs are managed. Face facts, the weirs are there to protect the marsh and by extrapolation the long term viability of the fishery. Provide me evidence that proves any of this wrong, and I will gladly admit that I am. SOUND evidence.
