The water was also rising perilously inside New Orleans' Superdome, and Blanco said the tens of thousands of people now huddled there and other shelters would have to be evacuated as well.
"The situation is untenable," Blanco said at a news conference. "It's just heartbreaking."
Because of two levees that broke Tuesday, the city was rapidly filling with water, the governor said. She also said the power could be out for a long time, and the storm broke a major water main, leaving the city without drinkable water. Also, looting broke out in some neighborhoods.
New Orleans lies mostly below sea level and is protected by a network of pumps, canals and levees. Officials began using helicopters to drop 3,000-pound sandbags onto one of the levees, hoping to close the breach.
All day, rescuers were also seen using helicopters to drop lifelines to victims and pluck them from the roofs of homes cut off by floodwaters. The Coast Guard said it rescued some 1,200 people.
New Orleans Mayor Ray Nagin said hundreds, if not thousands, of people may still be stuck on roofs roofs and in attics, and so rescue boats were bypassing the dead.
"We're not even dealing with dead bodies," Nagin said. "They're just pushing them on the side."
