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.
