They've been dredging Bayou Lafourche from Dville through Belle Rose.

Bids should be out for a new pumping station in Dville at the Mississippi river to increase the flow.

The weir was removed in Thibodaux a few years ago

Also need to open Bayou Lafourche to the Mississippi and create a diversion from the river into Lake Des Allemands. That would help create additional points of fresh water flowing into the Barataria Basin.

Being addressed as well.

The Bayou Lafourche Mississippi River Re-Introduction and Pumping Capacity Improvement Project in Donaldsonville has gone out to bid for construction.

Bayou Lafourche serves as a main water source in the area for residents of Lafourche, Terrebonne, Assumption, and Ascension parishes and provides water for agriculture and industry in the region. The restoration project will reconnect the Mississippi River into Bayou Lafourche, which then leads into the Gulf Intracoastal Waterway (GIWW), and Grand Bayou. It will help restore parts of the Bayou Region’s land loss and improve water quality.

The modernized pump station at the top of Bayou Lafourche recently received the final U.S. Army Corps of Engineers (Corps) permit which was a key component to completing the regional approach to reviving Bayou Lafourche. By increasing the capacity of the Mississippi River entering the bayou, the high flows will counter saltwater intrusion on the coast – countering coastal erosion – and improve water quality for residents of Lafourche, Terrebonne, Assumption, and Ascension parishes.

Great news!

A diversion to Lake Des Allemands, through Bayou Des Allemands flowing into lakes Cataouche and Salvador would help as well.

It seems to me that after reading all these good comments that we should try and return the lower Miss River to the way it was and not endanger communities from River flooding. In that way we could over time naturally rebuild marshland. Fishermen would gradually relocate as conditions dictate. We made a mess, it’s time to put things back the way they were a little at a time.

Sadly bayou terrebonne is a drainage ditch from Schriever through Thibodaux and was blocked off at bayou lafourche decades ago. Would have been nice for some of that water to flow directly into the terrebonne estuary

Do you actually know why we are losing marshes and coastlines in Louisiana right now? Have you ever read anything about it?


Does it matter? Nobody is going to do anything that affects the port cities, so nothing is going to change.

Must be finally encroaching on some politician's hunting camp.

While creating marsh via dredge isn’t THE long term solution IMO, how is creating marsh from sediment on a water bottom not beneficial?


I’m not talking about marsh creation only. I’m talking about dredging in general in LA. They just dump it back in the Mississippi River, Atchafalaya, etc. like 100-200 yards downstream.
