Levee Pump Fails; New Flood Coming

As Mississippi and Alabama help the living, count the dead, and begin the cleanup from Monday's assault by Hurricane Katrina, Louisiana is facing a new threat: rising water in New Orleans and word that things in the already catastrophically stricken city are about to get a lot worse.

New Orleans Mayor C. Ray Nagin says a new wall of water is expected to flow into the east bank of the city beginning around 8:30 a.m. or 9 a.m., causing floods of nine feet or more in some areas.

"This is the bowl effect that everyone has been talking about," said Nagin. "Water is now going to fill the bowl on the east bank."

Nagin told CBS affiliate WWL-TV that flood experts have told him that the new deluge, caused by the failure of a flooded pump at a levee with a break some two blocks wide at the 17th Street Canal, will continue until the water is at three feet above sea level: the same level as Lake Pontchartrain, the huge salt water lake on the city's northeast border.

Since New Orleans itself is below sea level, that means the flooding is expected to be enormous on many streets - the degree depending on how many feet below sea level each street is.

On famed St. Charles Street, that would mean nine feet of water.

The French Quarter, which was not devastated by Hurricane Katrina's original impact on Monday, is expected to be affected by the new floods, as is the city's uptown section.

Nagin had hoped to have Army Blackhawk helicopters drop 3,000-pound sandbags on the levee at Pumping Station No. 6 before it became too waterlogged to continue operating. That, he says, "didn't happen" because there were too many chiefs calling the shots in responding to the disaster, he told WWL-TV.

"My heart is heavy," said Nagin, as he ticked off New Orleans' current problems: no electricity, for at least four to six more weeks; contaminated drinking water; gas leaks sending flames shooting up from beneath the water; bodies floating in the water; a leaking oil tanker which ran aground; two bridges gone; both airports flooded; and no clear path in or out of the city.

Rescuers in boats and helicopters are continuing to pluck shocked and bedraggled flood survivors from rooftops and attics. More than 3,000 people have been rescued by boat and air, some placed shivering and wet into helicopter baskets. They were brought by the truckload into shelters, some in wheelchairs and some carrying babies, with stories of survival and of those who didn't make it.

Louisiana Gov. Kathleen Blanco said Tuesday that the tens of thousands of people now huddled in the Superdome - which is now surrounded by knee-deep water - and other rescue centers will have to be evacuated.

"Everybody's scared, worried, desperate, and the living conditions there are horrible, so we're moving them out and trying to give them a little bit of ease," Blanco told CBS News Early Show co-anchor Julie Chen.

The city is also without drinkable water. Other problems: looting, and a large group of inmates sitting on a highway watched over by relatively few guards, after being evacuated from a flooded prison.

An untold number of people are feared dead in Louisiana. "We have no counts whatsoever, but we know many lives have been lost," said the governor.

"We've fought hurricanes before. You know, we think we are hurricane-smart and there's some normal things that go on during the aftermath of a serious hurricane, but this is not normal. This is past the normal thing that we normally have dealt with over the years," Blanco said.

Nagin says hundreds, if not thousands, of people may still be stuck on roofs and in attics, and so rescue boats are bypassing the dead.

A congressional delegation is expected to do a flyover Wednesday for a preliminary assessment of the situation.

By midday Tuesday, Katrina was downgraded to a tropical depression, with winds around 35 mph. It was moving northeast through Tennessee and there are concerns that over the next few days, it could swamp the Tennessee and Ohio valleys with a potentially ruinous 8 inches or more of rain.

In Katrina's wake across the Gulf Coast, millions of people are still without electricity: at least 370,000 homes and businesses in Louisiana, at least 900,000 homes and businesses in Mississippi, and about 718,000 homes and businesses in Alabama.

In Alabama, two people were killed and the property damage is heavy, in some areas appearing worse than the impact of Hurricane Ivan last year. The flooding in Mobile matched a record set in 1917 and a major bridge there remains closed, after being struck by an oil drilling platform that floated away from a shipyard.

In Mississippi, authorities say the confirmed death toll for Harrison County - home to devastated Gulfport and Biloxi - has topped 100 and is expected to rise.

"We are very, very worried that this is going to go a lot higher," said Joe Spraggins, civil defense director for Harrison County, home to Biloxi and Gulfport. "We're just estimating but the number could go double or triple from what we're talking now."

"What I'm authorized to say now is we expect the death toll to be higher than anything we've ever seen before," said Jim Pollard, a colleague of Spraggins.

Bill Lokey, an official with the Federal Emergency Management Agency, called Katrina "the most significant natural disaster to hit the United States."

According to preliminary assessments by AIR Worldwide Corp., a risk assessment company, the insurance industry faces as much as $26 billion in claims from Katrina. That would make Katrina more expensive than the previous record-setting storm, Hurricane Andrew, which caused some $21 billion in insured losses in 1992 to property in Florida and along the Gulf Coast.

Monday, Katrina's remnants spun off tornadoes and other storms in Georgia that smashed dozens of buildings and were blamed for at least one death. Last week, 11 people were killed when Katrina came ashore in South Florida.

In Biloxi, Mississippi, areas that were not underwater were littered with tree trunks, downed power lines and chunks of broken concrete. Some buildings were flattened and there has been looting in some areas.

The string of floating barge casinos crucial to the coastal economy are a shambles. At least three of them were picked up by the storm surge and carried inland, their barnacle-covered hulls sitting up to 200 yards inland.

The deadliest spot yet appears to be Biloxi's Quiet Water Beach apartments, where authorities said about 30 people were washed away. All that is left of the red brick building is a concrete slab.

"We grabbed a lady and pulled her out the window and then we swam with the current," 55-year-old Joy Schovest said through tears. "It was terrifying. You should have seen the cars floating around us. We had to push them away when we were trying to swim."

"Many, many victims are thought to be buried under the rubble," said CBS News Correspondent Lee Frank in Gulfport, Miss.

Tens of thousands of people will need shelter for weeks if not months, said FEMA director Brown. And once the floodwaters go down, "it's going to be incredibly dangerous" because of structural damage to homes, diseases from animal carcasses and chemicals in homes, he said.

Monday, Katrina's remnants spun off tornadoes and other storms in Georgia that smashed dozens of buildings and were blamed for at least one death. And last week, 11 people were killed when Katrina came ashore in South Florida.

Officials warned people against trying to return to their homes, saying that would only interfere with the rescue and recovery efforts.

More than 1,600 Mississippi National Guardsmen were activated to help with the recovery, and the Alabama Guard sent 800 of its soldiers to Mississippi as well.

"This is our tsunami," Mayor A. J. Holloway of Biloxi, Miss., told The Biloxi Sun Herald.

Teresa Kavanagh, 35, of Biloxi, shook her head is disbelief as she took photographs of the damage in her hometown.

"Houses that withstood Camille are nothing but slab now," she said. Hurricane Camille killed 256 people in Louisiana and Mississippi in 1969.
