Premise: The Campos Novos Dam (also known as Barragem de Campos Novos locally) is a hydroelectric dam in the Santa Catarina state in southern Brazil. In 2006, at 200 m dam height, it was regarded as the third highest dam of this type (concrete-faced rock fill dam or CFRD) in the world, but, in June 2006, the water which it held back ran out following a break in the dam wall.
Hypothesis: The Campos Novos Dam is broken.
