Eden Isles, another Florida-type development, is located in the marshes on the north shore of Lake Pontchartrain near Slidell, La. The area was originally drained and reclaimed for agriculture in the early 1900's, but the project failed and the old fields were flooded. An intricate network of canals has already been dredged and homesites are being sold on spoil bank ridges adjacent to the canals. The total project encompasses 2,400 acres with 35 miles of navigable waterways having minimum depths of 30 feet by 140 feet wide. Eden isles is billed as a complete community with a commercial zone, school sites, and community park areas in addition to home sites

In the image below shows the damage inflicted on the marsh converted from brackish to freshwater by Carnarvon. This was the damage caused by Katrina alone. The images are 30 days apart.
What will the future Louisiana coast be like if the massive diversions are implemented. You don’t have to be a scientist to have a clear picture of the accelerated destruction of our coast.
Look at all the land created by DREDGING in my prior posts and future posts. All have endured 22 or more hurricanes, including Katrina, and are virtually unscathed.
Why is this diversion still running? CPRA, feel free to speak up!

Dredge don’t Divert! I could say more, but why?
Three coastal-restoration projects intended to rescue Louisiana’s rapidly shrinking wetlands have failed to restore marsh during the past two decades.
Instead, the schemes — which involve diverting fresh water from the Mississippi River in the hope of carrying sediment to marshes and aiding plant life — have made these regions more vulnerable to hurricanes, according to the authors of a study published by Geophysical Research Letters1.
… The Coastal Wetlands Planning, Protection and Restoration Act plans to restore almost 17,000 hectares of marshland over the next two to three decades, at a cost of US$1.05 billion. About 65% of the projected costs are for freshwater-diversion projects similar to those examined by the study, says lead author Michael Kearney, a coastal scientist at the University of Maryland in College Park.
… But the researchers found that total vegetation and marsh area in the three had not grown significantly. Moreover, the regions suffered greater damage during Hurricane Katrina than surrounding areas.
For instance, in the Caernarvon diversion, Hurricane Katrina destroyed the most vegetation in zones that received the most direct freshwater flow, even though these were far from the storm’s path.
Most of the new plant growth that has occurred since the diversion was built consists of algae and other floating plants rather than the deep-rooted marsh plants that hold soil in place. This, says Kearney, is due to the influx of nutrients from agricultural run-off and industrial processes.
“The amount of nutrients per acre is far in excess of what these plants can tolerate,” says Kearney of the marsh-building plants.
The researchers conclude that the scientific basis for freshwater diversions is not sufficiently established, and that the emphasis on diversions as a coastal-restoration strategy should be reconsidered.
Christopher Swarzenski, a wetland biologist with the US Geological Survey, based in Baton Rouge, Louisiana, agrees with their conclusions. “There’s a lot of arm-waving,” says Swarzenski. “There is no science to say that [freshwater diversions] will sustain wetlands or prevent wetland loss or build wetlands, which are the three objectives.”
…Kearney … “Even if freshwater diversions do deliver mineral sediment into the marshes — which I highly doubt — what would be the point if the high levels of nutrients these waters also carry essentially so damage [plant] roots that they die off?”
Jerolmack worries that Kearney and co-workers’ conclusions are “potentially damaging” to Louisiana’s marsh-restoration plans. “I think there’s still work to be done on understanding better the science of how we can build marshes using diversions, but we are doing that science,” he says. “And we are working on translating it directly into practice.”
On July 10, Congressman Cedric Richmond of Louisiana’s 2nd District introduced the DREDGE Act of 2012 – Dredging for Restoration and Economic Development for Global Exports. The bill would authorize deepening the present 47-foot Mississippi River channel to 50 feet, and create a pilot project to promote the rebuilding of wetlands using maintenance material from the river.
“The Mississippi River is undoubtedly the most important river in the United States,” said Congressman Richmond. “Its proximity to the Panama Canal is vital to our nation’s economy and critical to supporting the President’s goal of doubling America’s exports. With the introduction of the DREDGE Act of 2012, we are preparing for the future while strengthening our wetland restoration efforts. By deepening the Mississippi River, we continue to remain effective and competitive in the global market, while preparing the state of Louisiana to capitalize on an extremely valuable asset, our ports.”
In addition to deepening the Mississippi River, the DREDGE Act of 2012 calls for greater accountability concerning sediment disposal from dredging. This legislation directs the Corps to install a pump-out site in the Southwest Pass so that the sediment is no longer wasted and is instead used to rebuild the wetlands.
“My legislation also creates a pilot project to study the potential cost savings of using sediment dredged to rebuild wetlands instead of simply dumping it in the ocean,” said Congressman Richmond. “Currently, dredges working in the lower Southwest Pass dump sediment, the life blood of our wetlands, into the Gulf of Mexico. Estimates show that by redirecting all of the sediment dredged in the Southwest Pass, we can create approximately 775 acres of wetlands per year.”
The proposed legislation has received letters of support from the Port of New Orleans, St. James Stevedoring Company LLC, the Big River Coalition, and the New Orleans-Baton Rouge Steamship Pilots Association. Organizations supporting the legislation include the Crescent River Port Pilots Association, the Associated Branch Pilots, the Port of South Louisiana and the Port of Greater Baton Rouge.

MELBOURNE, Fla. — The first hint that something was amiss here, in the shallow lagoons and brackish streams that buffer inland Florida from the Atlantic’s salt water, came last summer in the Banana River, just south of Kennedy Space Center. Three manatees — the languid, plant-munching, over-upholstered mammals known as sea cows — died suddenly and inexplicably, one after another, in a spot where deaths were rare…

The evidence of decline is compelling. In 2011 and 2012, unprecedented blooms of algae blanketed the estuary’s northern reaches for months, killing vast fields of underwater sea grass that are the building blocks of the estuary ecosystem. The grasses are breeding grounds for fish, cover from predators, home to countless creatures at the bottom of the food chain and, not least of all, the favorite menu item of manatees.
The sea grass has largely been supplanted by macroalgae, fast-growing seaweeds that clump into huge mats that drift free in the waters. And the character of the estuary is changing: already, algae-eating fish like menhaden are significantly increasing, Mr. Rice said.
This has been an amazing week for the SLC! We kicked it off with a great outreach meeting on the northshore. A big thank you to Captain Dudley Vandenborre for being our guest speaker and to Fox’s Pizza for hosting us! We filled the room with concerned northshore fisherman and are happy to have them joining our ranks!
There we also got our copies of the latest “Marsh & Bayou” magazine, in which Linda Cuccia wrote an article on the Save Louisiana Coalition. The spirit of the SLC and what we are fighting for is truly captured in this article, where Linda recounts her fishing trip with the SLC’s president, Captain George Ricks saying, “As we slowly made our way out to the open water, he spoke of his childhood and the years he has spent in these waters. I knew Capt. George was not merely trying to protect his own livelihood, but an entire way of life, for generations to come.” It is wonderful to see someone who admittedly didn’t understand why anyone would fight against these diversions just a short while ago come full circle to understand the SLC so completely, it’s amazing what a fishing trip can do! If you haven’t picked up your copy of “Marsh & Bayou” yet, go do it now!
The high notes continued on Wednesday when several SLC board members and St. Bernard Parish President Dave Peralta met with Senator Vitter. The group was able to voice all of their concerns about the proposed diversions and the Senator was very interested in all they had to say. We hope this is the beginning of a continuing dialog with our representatives so Louisiana can make informed decisions in this matter as we move forward.
Finally, today I picked up my copy of “Coastal Angler.” It is jammed packed with articles and reports from the best of the best in Louisiana’s fishing industry. Captain George Ricks wrote another great article, “Truth, Justice, and Hypocrisy” giving us the truth about the dead zone, the hypocrisy of some environmental groups that are supporting the large scale diversions while suing the EPA over the polluted river, and the justice we are going to see when we save our heritage and way of life! There is a tour with Campo’s Marina owner, Robbie Campo, of his land built solely of dredged materials, land that now is thriving with vegetation and wildlife, land that survived all the hurricanes, and land that you can drive a bulldozer across! There is another article on Mitch Jurisich, his long family history in the oyster business, how they were hurt but survived all of the hurricanes and BP, and his fears that through all his family endured the river diversions may be the last straw for our oyster industry. And finally Captain Kerry Audibert, who not only has a Breton Sound fishing report, a great article on his trip where he “cleaned up” on trout with publisher Bruno Prager, but who is also featured on the cover of the magazine! Why are all these guys featured in this magazine? Because they are the best at what they do, NO ONE knows fish, crabs, oysters, or our marshes like they do. What else do all of these guys have in common? They are all board members of the Save Louisiana Coalition. They are from all areas of the fisheries, charter captains, a marina owner and crabber, and an oyster farmer, but they all agree on one thing, these proposed diversions will destroy the lives that they love along with the very marsh they are supposed to save. These men live, sleep, and breath these marshes and its waters, no one knows them better and no one could possibly want to save them more, that’s all the proof I need…..
