Isaac forces state to cut hole in Plaquemines levee Thursday
Wednesday, August 29, 2012, 6:34 PM
By Rebecca Mowbray, The Times-Picayune

The state of Louisiana will cut through a locally managed levee on the east bank of Plaquemines Parish Thursday to allow storm surge water from Hurricane Isaac flow back into the Gulf of Mexico.

On Wednesday, the state reversed the pumps at a fresh water diversion project at Caernarvon to drain storm water from the Braithwaite area of Plaquemines Parish into the Mississippi River.

That move succeeded in lowering the water level in the area from about 14 feet down to seven feet, but the effectiveness of that move was exhausted when the remaining water in Plaquemines equalized with the water flowing down the Mississippi River.

Exhausting remedies with Caernarvon meant that Louisiana needed to move on to more drastic measures.

Garret Graves, head of the Coastal Protection and Restoration Authority said the state signed off on the plan to start digging through a local levee near Braithwaite as soon as tomorrow, assuming conditions allow.

Water levels in the Gulf of Mexico need to have dropped for the water to flow of the breach that the state will create.

Meanwhile, the Army Corps of Engineers is trying to get temporary pumps that can help drain Plaquemines. Earlier in the day, Plaquemines Parish President Billy Nungesser had asked the Corps for its opinion on deliberately breaching the levee, but weather and high water won't allow the Corps to go out and inspect the area until tomorrow.

The state is following a playbook written in Hurricane Gustav in 2008 when it also reversed the flow at Caernarvon and cut a hole in a local levee.

Nungesser said the state cut a breach near Myrtle Grove to drain the area in three to four days instead of the two weeks that it was expected to take.

State and local officials are also worried about flooding on the west bank of Plaquemines as now Tropical Storm Isaac makes its way inland.

Heard many tidal gages on LA coast got within foot or two of record. How does a cat one challenge cat 3 and 4s. Answer it wasnt a cat 1
This storm was a beast of a storm. It is hard to believe that it hardly moved in over 24 hours which kept torrential rain and high winds bombarding the area for much too long.

I'm sure there were many people who had did not think it would stay with them as long as it did.

Hurricane Issac has been a fascinating account of weather, geography, engineering, and humanity.

So far, I have not heard of any loss of life and I pray that remains the case.

The center of circulation is just about to pass directly over my location. Blustery, a few leaves and pine straw in the yard. On the way to coffee this morning, you would see the odd dead snag tree blow down. Maybe 1 1/2" of rain so far. Nothing here that wouldn't happen during any March windstorm.

I'm glad you were not affected by the storm.

You know it is a serious storm when

It caused the postponement of the Louisiana Tech vs Texas A & M football game. It will be played in Oct 13

The scuttlebutt around town is that weak ticket sales from A & M might have been a factor...

La. orders evacuation after Miss. dam threatened
Posted: 9 minutes ago

MCCOMB, Miss. — Louisiana officials have ordered evacuation of low-lying, sparsely-populated areas along the Tangipahoa River because an Isaac-hammered dam at a state park lake in southwest Mississippi near the Louisiana border is in danger of failing.

Officials in Tangipahoa Parish, La., fear the water it would pour into the already swollen river would flood low-lying areas downstream from the park.

But Mississippi officials say they don't believe the volume of water in the 700-acre lake at Percy Quin State Park near McComb, Miss., would add enough flow to threaten communities downstream.

That one took me a second!

The northwest edge is supposed to bring rain for Kansas City tommorow & Saturday. I anticipate the winds will have mostly died down by the time it has come this far on land.

In Slidell, La. areas never flooded, including during Katrina in 2005, saw up to five feet of water after drain pumps were overwhelmed
