How to sinking a barge in Bayou Chene prevent backwater flooding?
I don't understand this, either. Can someone please fill me in. Use small words, too, because I'm kinda stupid.
I have this mental picture of a barge sitting at the bottom of the channel with water just going over it. Is that picture wrong? Is the barge that much taller than the depth of the channel that it'll essentially just be a dam?

Yes the barge sits on the bottom and they might pile up limestone or concrete on top of it as well. It is definitely a dam that should not allow water over the top. Those channels are usually pretty shallow in places, sometimes less than 5 or 6 feet. I just checked my Garmin chartplotter software and it says the bayou chene at this point is "dredged to 6 feet", so there it is. Should be about 6' in depth, no problem for that barge to dam up.

Okay, then I was severely overestimating the depth of the channel. Thanks, guys.

This is from last time but it should be pretty much the same this time around.
You're right that's it basically just a dam that prevents backwater flooding of the area east of Morgan City.

They drive sheet pile on the sides and around the barge after they sink it
Here are some pictures from 2011 and 2016 when they did it

Opening has been delayed until June 6th. Apparently there are complications with the river forecast.
June 6th is just as the levels start to creep back up again.

Fa why?
Posted on 5/30/19 at 4:01 pm to Teddy1388
Someone couldn't get their cattle out in time and another farmer needed extra time to haul out his crop.

The article doesn't say. It's very weird.

Maybe the COE is stalling hoping to not have to open the spillway

Facebook Video link to St. Mary Levee District
animated graphic that shows where the barge is located in Bayou Chene and what are will be impacted (benefit) from stopping the water at that point.
