The Breton estuary (site of the Caernarvon diversion) before and after Hurricane Katrina's landfall.
The Caernarvon diversion is capable of putting out 8,000 cubic feet per second (cf/s) of fresh water into the surrounding brackish marshland, but on average hovers around only 2,000 cf/s.
The Caernarvon diversion caused 42 square miles of surrounding land to wash away over night after Hurricane Katrina hit St. Bernard Parish in 2005. Many scientists attribute this to the nutrient-rich river water substantially weakening the delicate root systems in the marsh causing it to roll up like a carpet.
By comparison, the Biloxi and Pointe-a-la-Hache marshes, directly above and below the Caernarvon diversion influence area, suffered only a small amount of land loss due to the storm surge.
The state and outside environmental groups are now pushing for a diversion 30 times larger than Caernarvon! That amount of fresh water is capable of filliing lake Pontchartrain in 7 days!
The commercial and recreational fishing as well as the vital storm surge protection that these estuaries provide will NOT survive!
