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). Islands with sufficiently high land and asset values are repaired each time they are flooded (becoming white again). Other islands remain flooded.
NOTE: The probabilities of failure are from the draft Delta Risk Management Strategy (DRMS) study. Future conditions are likely to be worse than those depicted here, because these probabilities do not account for the effects of climate change (sea level rise and increasing winter floods).
