Issac just got real, This is scary scary stuff. I hope they are able to get everyone out in time. My thoughts go out to the people of LA.

[Updated 12:10 p.m. ET] Pike County Civil Defense's latest Facebook update says: "Flood warning for the Tangipahoa River at Osyka. The dam at Lake Tangipahoa, better known as Percy Quin State Park, has been damaged by the torrential rains from Hurricane Isaac, but is intact, and is not leaking. We are monitoring it. All residents below the dam that live along the Tangipahoa River are being notified of the damage."

[Updated 12:07 p.m. ET] As of about 20 minutes ago, a National Guard helicopter was maintaining position over the dam to monitor its integrity, The Times-Picayune reports. As of 11:45 p.m., it was still holding, the New Orleans paper reported.

Hey McComb is several miles UPSTREAM!!!! as in NORTH. Magnolia is south and near the creek that the dam will take out

Wheres Obama and FEMA?

Glad they have a Governor to take swift action and get those people out of there. Don’t want to interrupt Obamas campaign stops.

This ticks me off to no end. Its reported all over the news that its a CAT1 storm. It may have low winds but its a super slow moving storm. Dumping TONS of water in an area that is under a severe drought. Severe drought plus lots of water equel flash floods.

where is the news conference?

nvm, video is up now

This is mostly a earth dam, once there is one breach the rest is sure to follow.

You are completely wrong. Here are all of the things FEMA already has in place. Including plans.

Sorry, not gonna pull a George W. this time around.

If you read his Memoirs, which I have, you'll know exactly why he didn't land.

Link says it drains into 56 square miles!!!! That's a lot of land to cover and I'm sure there is a town or two in that 56 miles. Not a major city or population area but still very very scary and dangerous!!

I think any political allegory attempted here would be in bad taste. but...


Percy Edwards Quin (October 30, 1872 – February 4, 1932) was an American politician from Mississippi. He served as a Democrat in the United States House of Representatives from 1913 to 1932.

edit on 30-8-2012 by GuidedKill because: (no reason given)

The earthen dam, at the time I believe the largest earthen dam in the world at Oroville CA, was cracked during an earthquake but it did hold and was repaired. It was they said cracked all the way through near the bottom.

satelittle image of the dam and the water it is holding back

CNN reports same. Fifty to sixty thousand being evacuated.

Interesting. I hope it's more MSM created "panic and doom" and not a real threat. Would suck to have a 6 foot wall of water tearing at you!

You can be swept away with as little as 1 foot of water at 15 MPH. Now imagine you get swept away at 15 mph and hit a tree head on…. Your dead. It is dangerous

Due to the dam failure, water levels on the Tangipahoa River near Kentwood are expected to rise to 17 feet quickly. This is a very similar level to what was experienced in 1990 and 1983. If you were impacted by the floods of 1990 or 1983, leave the area immediately for higher ground.

www.google.org...

Weather channel now reporting that there is a 100 foot breach in the dam. Flood stage for the river below the dam is 15 foot. The current river level is 17.5 foot to 21 feet in some areas.. River levels are expected to rise to over 21 feet and maybe even 28-30 feet if the dam breaks.

At least that's what the weather channel lady just said.
