Nearly 200,000 People Evacuate After Warning Dam Could Collapse - A Must Watch Video

Residents living near the Oroville Dam were warned of what officials at the time called an imminent threat that the spillway, designed to drain water from Oroville Lake to prevent it from topping the dam itself, might fail.
