re: Crabbing in Lake Ponchartrain

I find it hard to believe that the wall (marked in red) and a closed off channel (marked in yellow) have adversely effected the tidal flow in and out of Lake P enough to cause the supposed decrease in #'s seen of shrimp and other wildlife in Lake P.

I think it has more to do with the record rains up north over the past couple years keeping salinity levels lower in Lake P, compounded by the opening of the Spillway several years back. I believe it's just a matter of salinity levels being lower over the years since the spillway opening.
