On the Calcasieau Ship Channel the material dredged is placed into the placement along the channel and testing is conducted daily using a hydrometer to ensure that no dredged material is placed back into the channel through the weir boxes. Unless USACE specifies for overboard pumping. Currently I am working on a project in Morgan City near the Berwick Locks and we are pumping dredge spoil overboard but it is sand not silt and is tested to see where the material is flowing. The placement areas along the Calcasieau Ship channels are becoming usless due to the amount of the material that has been placed into them over the years. There have been failures in the levee structures that empound the dredged material due to the material that is used to construct these levee's is what we call liquid soup. The placement areas are so full that along the shoreline and in the channel the ground is being pushed out and up. So I agree we do need to put the material back into the marsh where it belongs
