No JimBeam I am not. This is why I think this discussion needs more attention. The more informed I have become on the subject the more I think the diversions will accelerate coastal erosion. Unfortunately, most people buy into the "spend tax dollars hoax".

quote from Ricks "Last night I was invited to the CCA meeting at the Dock in Slidell, and was surprised at the great turnout. I was honored they let me speak and let people know what is going on with the Diversion issues. What amazed me, was that of almost 100 people, only one person was aware of the Master Plan for Coastal Restoration and what it's going to do!! When I informed them of the facts and figures of exactly how much freshwater will be pumped into our beloved saltwater marsh with the scheduled diversion at Braitewaite, you could hear a pin drop!! It was gratifying to have so many come and shake my hand and thank me for what we're doing to get the word out."

As long as there is a sediment load that meets the requirement, freshwater diversions will not hurt rebuilding the coast. Look at the Wax Lake Delta, among others

The last discussion went like this:

Freshwater diversion =/= sediment diversion
Freshwater marsh =/= saltwater marsh


That basically sums it up. Until you get the sediment diverted, not much is gonna happen

The maps on the master plan show most areas of Plaquimine and St Bernard with brown dots, meaning they are scheduled to be improved with sediment diversion which is supposed to build marsh.

I see CFS figures, but that measures water flow, not sediment load. Does anyone have reliable information on whether the proposed diversions will carry more sediment than Davis Pond or Caernarvon.
