interactive Delta Island Flooding (No Repairs) Jul 1, 2008 This animation depicts how the Delta may change over time as a result of levee failures from earthquakes and floods. Islands that lie below sea level will flood after levee failures (becoming blue). If islands are not repaired after flooding, the entire area is likely to be flooded by 2055.
