"Low salinity marsh experienced more than twice as much land loss by percent than high salinity marsh."
"The failure of low salinity wetlands was focused in the interior regions of Breton Sund, the western Chenier Plain, and the more exposed regions of the Birdfoot and Wax Lake Deltas." (from Howes et al 2010)

Councilman Cavignac working on most pressing issue facing St Bernard and Plaquemines Parishes.
Centerpiece of State master plan for coastal restoration contains several large scale river diversions for St Bernard and Plaquemines Parishes.
Salt water and brackish marsh areas were able to withstand hurricane damage while fresh water diversion area at Caernarvon withstood more damage.

the promised land gain is not occurring
and its not land that stands up to surge, not land that protects us
the problem is not the sediment, its the delivery system; it brings economic loss with fresh water influence and puts coastal towns under water
render wetlands more susceptible to storm surge, changes the drinking water as far north as Orleans
Cost Effective Study does not include all information
The science is flawed in the cost of diversions vs the cost of diversions, according to a study by the Louisiana State University.
Initially dredging seems more expensive, but all the costs are not considerd, including and additional $1.8 billion for operation and maintance and additionally the economic impact of loss of estuaries due to diversions
