re: Louisiana State Tax refund

Well, OP, what happened?
0
Well, bayou manchac has been rising steadily from the swamp draining into it. Looks like the swamp will get a bout 3" lower in the next day or 2 and then the rate of fall will drastically slow.
Just got this update from the council woman:
"The Alligator Bayou Lock in Iberville is open, with no adverse affect on BM water level. Frog Bayou Lock being opened. Cut is now 1ft deeper and will be widened today."
This is good news!

No
Swamp is down 1/4" since noon. So that's progress.
Well, the water is about a foot over the half way mark on my 8' fence out back, and the water is usually a bit under that.
So 8' is about where it normally is. Currently at 13.07' as of 1 pm

Well, she was wrong about the pump flows. 130k GPM total for all 3 pumps. 300k GPM on the cut.
15 billion gallons of water to lower it 4 ft.
That means 2"/day and 24 days to get it down 4 ft, with no rain.
Gonna be a long haul.

Alligator Bayou was cut at noon today, hope the level starts falling!
New Projection with more data:
Manchac will be 2 ft lower than the swamp on Friday morning. Proving to be quite a linear trend:

The council woman also said there are 15 billion gallons of water needed to drain out of Spanish lake. With 3 pumps @130k GPM each and cutting the road for 300k GPM, it will take 15 days to drain the lake.

From council woman Teri Casso regarding flow rates:
"130k gallons per minute per pump
Cut will give us 300k"
"130k gallons per minute per pump
Cut will give us 300k"
Projection for manchac levels. Wednesday at 11 am, manchac should be 2 ft below the swamp level and will start draining.

Everything along Bayou Manchac. Airline at Manchac. Old Jefferson at Manchac. All the subdivisions that feed into Manchac. You remember the worries when the dam at Percy Quinn almost failed a couple of years back?
The cut won't flood those places. Manchac will never get higher than Spanish lake, erosion or no erosion. Spanish lake is at 13 ft, so when they cut, worst case is manchac gets to 13 ft.

Got any more pictures of the pumping? Can the public go see it (by public I mean myself)

Really? I thought Manchac would have to be lower than 13' to begin process.
Manchac only has robe lower than the road to begin pumping

So I did some back of the napkin calculations and it would take 4 pumps capable of 90,000 GPM per pump in order to pump the swamp down by an inch a day.
Anyone know the capacity of these pumps? Cause 90,000 gpm is a massive pump.

Anyone with an update on ridge/bluff? Over at my folks in Galvez gutting their house and I'm getting flash flood warnings. Only had 6-7 inches to spare and this rain is stressing me the frick out.
We are in the same boat. This sucks
