This is why my father & I are going off of what we see. Not what the news is telling us.

That comment could mean a ton of things, including just the opening of the BC spillway. Or he could have no idea what he's talking about.

That's what makes the "everything is going to be ok because thier are going to drop 20,000 barges & fix the river so crazy"

Damn dam

I worked on the Mississippi for 3 years & hated it. Too big, too fast, & too cold. We always told the new guys, "that work vest you wear is not to save your life. It is so when your body pops up 2 weeks later from some barges, you mother has something to bury."

It wasn't told as a joke either.

Key flood locations identified by the ACE which have the greatest potential to fail per post 2011 Flood report:
Post 2011 Flood Damage report by USACE

1. Baton Rouge Front
2. Duncan Point
Duncan Point is an area of historic seepage. A massive aquifer in excess of 300 feet deep exists beneath the levee overlain by a thin blanket of confining material. This blanket has been ruptured and the situation continued to deteriorate with successive high water events. The area was previously a historic sand boil; but in 2010, a stabilization berm was constructed. As a result, the seepage moved from the berm to an area north along the protected side toe of the levee. There was extensive seepage at this site to include a sand boil at levee toe and soft, spongy conditions one-third up the levee slope, requiring extensive flood-fight efforts. A temporary, berm was constructed using 12,000 sandbags to reduce seepage in the most critical reach of the site. Adjacent highway experienced spongy conditions requiring
closure.

3. Chalmette Seepage (fixed)
4. Jackson Barracks Slope Paving (NO SWB purportedly fixed)
5. Old River Seepage
6. Blackhawk Slide
7. Audubon Seepage (by John James Audubon Bridge)
8. Pointe Coupee Seepage
9. Point Pleasant Seepage
10. Algiers Seepage
11. West of Berwick
12. Bayou Chene
13. Old River Control Complex

Duncan Point is just south of Baton Rouge--downstream from LSU. Last flood ACE had to send in and place 122,000 sandbags to help form a berm to protect the area. There is a 300 foot aquifer underneath the levee which allows the area to incur massive seepage issues. The USACE has placed this entire area in its highest category of risk for a likely levee failure. Brightside to Gardere to BREC Farr Park area. It would have flooded all areas of Baton Rouge not on the natural ridge.

River Bank Repair at Duncan Point not yet begun on latest damaged area

Several cuts in the river bank were created this summer after high water in the Mississippi River receded quickly.

A Pontchartrain Levee District inspection after the water receded revealed two deep cuts in the river bank on the river side of the levee, said Rene Poche, a Corps spokesman.

The sandy material is about 100 feet riverward from the base of the levee, with one cut about 12 feet deep and the other about 20 feet deep, Poche said. The repair work will be done by Corps workers at a cost of about $200,000.

The levee remains stable and undamaged, and there were no problems caused by the cuts during the latest high water, Poche said. The repairs will help ensure that the scour won’t continue the next time the Mississippi River rises.

45 million gallons of water flowed through latest Duncan Point cracks

High water levels in the Mississippi River during the summer and the subsequent rapid drawdown of the river in August led to two large cuts in the east bank of the levee near Duncan Point in south Baton Rouge, with 45 million gallons of water slipping through those cracks into an uninhabited area in a six-day span.

Now the U.S. Army Corps of Engineers in New Orleans is proposing a plan to fix levee and is asking for public comments on the plan.

sounds like the next few weeks will be interesting
Mother Nature getting cranky after the holidays...

Yup. Levees failing all over the place up north & no change to forecast from 5 days ago.
