What happens if the Mississippi River is high?


At full blast, the Comite diversion Canal is to the Mississippi River as a horse fly is to an Elephant's arse.



I think the question is more concerned with what if the elevation of the Mississippi is higher than the elevation of the Comite. Would the Mississippi flow into the diversion canal instead of vice versa.

I am not familiar with the project, but I am certain there would be some sort of a control structure to prevent that.

They took away the free Blue Bayou!

Is this going to be a dry basin canal or will it have constant water?


I think there are pumps to ensure constant flow.

So who's going to build the first bar on it?

Will this cause the water level in the Amite to become even lower than current?



IDK.

I'm wondering if it will cause the Comite to flow backwards between the Amite and the diversion canal during high water.

Should be a huge help for flood protection. But I wish they'd build the Darlington Reservoir upriver from Denham Springs.

They don't even pretend it's going to be on time. I wonder how many people have made their fortune stealing from this project so far? They aren't going to want to give up that gravy train. The catered lunches alone are enough to delay it. Screw the tax paying people getting flooded.

They are building a gay bar right in the middle of where it's supposed to go. It's going to block the whole project.

It's called The Pork Barrel.

I think he was referring to .... what if the water level in the Mississippi is too high to allow the water from the Comite to drain into it.


I would imagine that would require the Mississippi to breach the levies which will frick everything regardless.

OT experts said that Top Golf would never come to Baton Rouge.

When it did, the OT experts said that Top Golf would never be successful in Baton Rouge.

When it was, the OT experts claimed that there are only about 350 people there on any given week.

Finally, after 40 years of collecting money from taxpayers.

Now hows about dredging the fricking Comite and Amite Rivers to better assist with flood control farther south of the diversion.

Where the diversion canal empties into Lily Bayou and eventual into the Mississippi R. there is a bluff there, not a levee. It is part of the same bluff that you see in downtown Baton Rouge.
The levee on the Miss.R. ,on the east side really begins in the area of the new state capital.

For the Miss.R. to be able to back up into the new diversion canal it would have to be at flood stage of over 100 feet high , which would come over the levee at the Vet. school.

That's a big no can do on the Darlington Reservoir. I purchased my dream property about 8 years ago in St. Helena, and my property in right on the edge inside the dry reservoir. My mailbox on the opposite side of the street is not located inside it, go figure.

Why should I have my life upended for the lack of insight and planning of others in the lower Amite River basin? The government should have considered the types of buildings they would allow on both sides of the river, and made provisions for proper water shed or don't build there.

Look, I am not being calloused, for I understand the flooding issues. I am from Denham Springs. I vividly remember the '83 flood, as well as various other floods not as bad. I even had to boat out in French Settlement on my wedding day to get to the church back in January '98. In '16 I had family members who either took on water for the 1st rime or lost homes. I spent 3 weeks afterwards helping many people with demolition, as did so many others. So I am not speaking from a lofty position looking down on others in water's way. I am just saying why should I, and the others whose families have lived on that land for generations be forced to give up their homes and land because Livingston Parish was not smart enough to plan for this?

There's a lot of misunderstanding in this thread about how this diversion will work:

The Comite and where the diversion canal starts at the Comite is much higher in elevation than the Mississippi River. They have to build several "fall" structures to help slow down the water so that it isn't a white water rapid as the water falls in the short few miles to the Mississippi. The Mississippi will never flow up the canal.

The start of the canal is built higher than normal river height for the Comite, so the diversion canal will be dry 90% of the time and will only have water in it when the Comite river gets above flood stage. The flood waters will go down the diversion canal instead of further on to the Amite, thus alleviating flood waters on the Amite as well. Several structures will have be built along the diversion canal so that intersecting creeks, bayous, and canals wont take on the diverted flood water and just send it back through Baton Rouge down one of these bodies of water.

This canal will not be navigable, there's no need to try and build a bar on it. It will not affect the current water level of the Amite.

This project only fixes half the problem. The Amite River still needs to be dredged, and the weir at the Ascension Parish Diversion Canal needs to be fixed.

What will be the rate of flow once it’s cluttered with tires, shopping carts, abandoned cars and the occasional cartel victim?

They’ve been building the US 61 bridge over it for a while now.
