2011 Mississippi River Spring Floods

_ Is there any possibility of the flood waters cresting I-10? _

Current worst-case projections say it won't with the crest being about 4 to 6 feet below the level of the Basin Bridge.

Does that change the structural integrity of the bridge? Having that much water flowing beneath it.

What would happen in a worst case if they opened the Morganza and had mechanical problems and could not close it?

I do not think that would be a problem. These are not automated gates. They are manually pulled up by a crane. Also, the river will receed at some point this summer where water would not flow through the gates even if they were left opened.

Here is a good reference story on the Mississippi River and the River Control Structure.

Helmut,

Could you go down to Morgan City and explain the dredging part you posted to them?! Maybe they'll listen to you!

Chop,

The gates are lifted with cranes on the structure. If they would break down there are extra parts, and if there is still a problem they could be placed back with a mobile crane. The gates themselves slide into slots and have rollers on them.

Red,
I understand the max of 15 feet, but what you can't see is that there is another body of water behind me. From my house, water naturally flows towards the basin so Fausse Point would have to back up before the flood reaches my area. If the water reaches me, then there will be alot more people underwater. I'll keep posting pics to show the level once it starts rising.

This was an amazing read. I knew SOME of the history behind these waterways and structures, but no where near this much.

thanks
