Engineers have known that Oroville’s backup spillway was unreliable

Early one September morning in 1975, in a quiet Metairie subdivision west of Transcontinental Drive, a ranch house suddenly exploded in a fireball so powerful it damaged 20 neighboring buildings and broke windows a mile away. The house plus four adjacent homes were reduced to rubble, and 11 people were seriously injured.
