Re-plumbing the Mississippi River: Are sediment diversions the right move?

CPRA seeks OK for Mid-Breton Sediment Diversion Project

Join Jacques and Simones as they dedicate an entire Delta Dispatches episode to the Coastal Protection and Restoration Authority's proposed Mid-Breton Sediment Diversion project, which is now entering the NEPA scoping process.

If approved by the Corps of Engineers, a sediment diversion structure will be installed in mainline levee on the left descending bank of the Mississippi River at approximately River Mile 68 and extending into the Mid-Breton Basin in Plaquemines Parish, .

When  river flows exceed 450,000 cfs (cubic feet per second) at Belle Chasse, the structure would divert up to 75,000 cfs of sediment, freshwater, and nutrients into the Breton Sound Basin. When flows drop below 450,000 cfs, the structure would divert a base flow of up to 5,000 cfs. If built, the project is expected to build new marshland lost to erosion and subsidence but significant environmental issues have been raised and must be evaluated.

Jacques and Simone break down the project, the EIS scoping process, and talk about how you can submit comments to the Corps. Catch this great show dedicated to the continued efforts to replumb the Mississippi River.

In 2015, he participated in Greater New Orleans Foundation’s Emerging Leaders program, in 2016, Jacques completed the Institute for Environmental Communication at Loyola University, and in 2018, he was an Aspen Ideas Festival scholar. Gambit selected Jacques as one of its “40 Under 40” for 2018. | As Executive Director of Restore or Retreat, a non-profit coastal advocacy group working to identify and expedite the implementation of aggressive, large-scale restoration projects, Terrebonne Parish native Simone Theriot Maloz works with Restore the Mississippi River Delta on the local, state and federal levels to advocate for the needs of the disappearing Louisiana coast, specifically the Barataria and Terrebonne Basins. Since the devastating hurricanes of 2005 and the 2010 oil spill, she has also been tracking the process of the different planning efforts underway, including the Natural Resources Damage Assessment Act (NRDA), Clean Water Act Penalties, the 2012 and 2017 State Master Plan Update and the Louisiana Coastal Area Study projects, all to ensure the needs of the Barataria and Terrebonne Basins are being adequately met with the necessary sense of urgency in the face of what is at stake. She was appointed to serve on the Governor’s Advisory Commission on Coastal Protection, Restoration and Conservation in the summer of 2014, and is a member and co-chair of the Commission’s Diversion Subcommittee. Simone plans on having the Louisiana coast continue to serve as her home and the home of her children and grandchildren.
