According to informal surveys following the February evacuations ordered in response to the Oroville Dam crisis, a large segment of the local population said they stayed at home rather than leave for higher ground. From the looks of an inundation map created by graduate students at the UC Irvine Department of Civil and Environmental Engineering, those residents who stayed behind might have wanted to rethink things. The recent study conducted by the graduate program forecasts the potential destruction that could have followed a complete failure of the emergency spillway at Lake Oroville.
