The dam, the volume includes 50,800 m³, was completed in 1962. He has since then served the water regulation on the Rio Jaguaribe and hydropower generation.

Dam accident

Before the completion of the Orosdamms and even during construction - on 25 or 28 March 1960 ( but probably on March 25 ) - broke the dam and caused a tsunami which killed some 1,000 deaths. The disaster happened at high tide due to unexpectedly heavy rainfall. The dam was flooded and washed away. However, the failure of the structure could be predicted several days in advance, and therefore the people could be warned so that 100,000 people were saved.
