$130 million approved for Maurepas Swamp river diversion project today

The diversion will flow at a rate of 2000 cfs per day for a period of 6 months per year. This is expected to stop brackish water from entering Lake Maurepas and ultimately make Lake Pontchartrain fresher.

Administered by Louisiana Coastal Protection and Restoration Authority (CPRA), the project will benefit more than 45,000 acres, providing a wetland buffer that can reduce storm surge for surrounding communities. The goal is to bring fresh water back to the area in Saint John the Baptist Parish.
The project lands include the construction of three 10'x10' box culverts in the Mississippi River Levee. The 5.5 mile-long diversion will start near Garyville and provide sediment and fresh water to existing wetlands in Maurepas Swamp. Other project features include road and railroad crossings, pipeline and utility crossings.
A new two-mile conveyance channel will then flow into the existing Hope Canal, which will be enhanced with small earthen levees for the last 3.5 miles into the Maurepas Swamp outfall area north of I-10.
The total project cost is $200 million. The plan is to break ground in the next two years.

Wow, my coworker's girlfriend is a grad student at LSU and was just telling me about this plan at our office Christmas party.

I remember in the 90’s they were going to do this to the Everglades. Then for the last 20 years they’ve tried to stop the problem they created.

Care to go into more detail?

An annual fresh water flushing is what that swamp needs. Its dying a slow miserable death right now.

This actually makes sense. It will improve the health of the swamp and also improve freshwater fishing.

This has been talked about for quite some time, almost 2 decades or more...takes forever to get anything done...swamp will be half dead before they move the first shovel full. It is a shame.

Its 3/4 dead now.
I just hope they do it and properly manage it. One good flush will make a drastic difference.

The 2016 flood helped a lot...

Good news. This project has been on again off again for awhile. I hope they design it to flush the water through the swamp west of I 10 and not just funnel it straight down Blind River.
That whole swamp has become a dead zone for fish and ducks because of a solid mat of green death blocking light from entering the water.

I remember going to a public meeting about this. I think it was around 2001 or 2002. They said that it could be in service as soon as 2012.

Sorely needed to save the swamp, but guessing it won’t do wonders for the saltwater fishing at the twin spans, trestles and such.

How long till the Mallards pile in?

How are they going to fund the remaining $70 million? This project will never go anywhere

Welp my former employer is probably ecstatic. They will probably be managing this grant for CPRA with La OCD.

"A total of $130,000,000 is being requested from FPL 3a to fund construction of the River Reintroduction into Maurepas Swamp Project. The amount requested is not inclusive of the total construction estimate of $190,000,000. The remainder of construction funds will likely be requested from the Spill Impact Component and/or other source(s) to take advantage of leveraging opportunities described above involving the combined construction of the West Shore Lake Pontchartrain Hurricane and Storm Damage Reduction Project and River Reintroduction into Maurepas Swamp project as it relates to the shared components of both projects."

Exactly what I was wondering. Not that I really care, I'll find trout elsewhere, but this will definitely bring more freshwater in.
That said, if it also brings more land in, it's a good thing.
