As the waters in New Orleans are pumped back into Lake Pontchartrain, authorities are bracing for another dose of tragedy to be revealed.
The Army Corps of Engineers is pumping water out, after closing a major gap in the levee that breached during Hurricane Katrina, flooding 80 percent of the bowl-shaped city.
While pumping is likely going to take weeks, officials are expecting to find a layer of toxic sludge and bodies once the water is gone. The mayor says ten-thousand dead wouldn't be unreasonable.
Meantime, rescue crews from as far away as California are trolling the evacuated city for stragglers. But rescue workers note they can't force people to go. The mayor says water won't be handed out to the holdouts anymore.
