The last time it was dredged was in the 50s!

It seems like a lot of work will be ongoing ten years after the great flood, these projects make a lot of sense. I guess this can be a thread about floodwater mitigation too.

The weir was designed to send water down the Amite River but it failed and 80% of the water goes down the diversion canal instead. The lower Amite River is silted in and stagnant and as shallow as 4 feet while the diversional canal is 30 feet deep. The lower Amite is a mini-old river control structure failure that no one notices. Of course this dredging is only for a tiny stretch from Lake Maurepas to highway 22. The long stretch from highway 22 to the diversional canal isn't funded.. which means good luck.

So it's the first. phase from 22 to Maurepas that's funded for $20 MM.. That should help though right? If any stretch of river is clogged up it needs to be cleared out.

BTW how's the Comite diversion going? I thought I read something positive was moving on that too.

What I’m still searching my head over is how is St. John able to build a flood wall across the whole parish just about to block surge from the lake by diverting it elsewhere. I get wanting to protect your area but how do you have the right to just Chanel it up the road. The water has to go somewhere.

Never knew why that was installed. Cool.

How does dredging work on a river that doesn't really flow? Just a long arse hose out into the lake? Or some other low area?

Think it was St Tammany that walled up first and flooded St John.

At this point it might actually be cheaper to have pooled the money and built a wall across the rigolets.

I kind of wondered the same and just stop it further east but IDK. Just crazy

Will provide no benefit beyond navigability of that stretch of the river

This is not true, though. That's a huge misconception.

I am pretty sure one of the original design objectives was proportionate flow splitting the flow unequally.

Good.
Amite River Commission finally doing something with that $10 million they got a couple years back, other than drawing fat salaries...

I thought all this climate change was just going to effect famine and drought.
Why then would we worry about flood mitigation?
