Spinnoff thread: From tarpon thread, Pontchy dredge pits and marsh creation


From this LINK is the following statement:

quote:

"This dredge hole was created during the dredging for the LaBranche Wetlands Marsh Creation Project (CWPPRA Project PO-17). T.L. James and Company began the work in November 1993 and it was completed in April 1994."


How do you all think that project turned out? Money well spent?

Will the current "dredge will create marsh" groups at the diversion meetings look at past dredge projects to see if they created sustainable marshlands?

The area they filled during that project is just about the only healthy marsh in entire LaBranche Wetland.

That project ended up building fantastic marsh. There's a similar project about to be done on the same property. PO-17 stands as one of the most successful CWPPRA marsh creation projects ever constructed.

That's real interesting because that project can really shed some light on the current arguments IMO.

IIRC after completion weren't the nutria over grazing that area? for a while they thought they were going to lose most of what they created...can't remember the remedy besides plans to exterminate the nutria...

I guess if it's still there, then it worked...

in other marshes on the north shore of Lake P they've bermed-in and filled in what was open water with dredged material from the lake in the last few years. This new marsh is stout and the grass is thriving. There are more projects like these planned for other areas in danger of getting out of hand to be undertaken within the next year or so.

dredging does nothing regarding salt water intrusion

Not directly, but the more marsh you put between the gulf and an inland ecosystem the harder it is for the saltwater to get in. You can't stop the tides, but the idea of putting a bunch of shite between yourself and it is not a bad idea. A combination of marsh creations, freshwater diversions, shoreline stabilizations, and other methods on every project would be ideal, but nobody wants to spend the money required. There are great restoration projects out there that can't get past all of the permitting and funding hurdles. Everyone wants to do something on someone else's dime, in unattainable time frames.

Yep. There are 2 in the design stage in that area now. PO-17 is a great project that will be there for many years.

I don't know. There aren't many who would argue that dredging to create new marsh does not work. It pretty much always does. It's just the cost of the dredging.

When PO-17 was built, it was about 5 or 10% or the cost it would be today. Dredging works, but finding sediment and doing it in a cost-effective way are not always possible.
