Searching For Survivors, Assessing The Damage

Death and decimation in the wake of Katrina, now a tropical depression, moving northeast.

Authorities along the Gulf Coast are assessing damage -- finding New Orleans, 80-percent underwater and looking at the threat of more rising water from a breached levee.

Rescuers aboard boats and helicopters are looking for trapped survivors. In Mississippi the death toll is upward of 50 people, and 30 of those are believed to have perished in an apartment complex. Residents who evacuated coastal cities in Louisiana and Mississippi are wondering when they'll be able to return home.
