Açude Orós, officially known as Açude Presidente Juscelino Kubistchek de Oliveira, is one of the most significant reservoirs in the state of Ceará, Brazil. Formed by the damming of the Rio Jaguaribe near the municipality of Orós in the center-south of the state, this massive impoundment was completed in 1961 by the Departamento Nacional de Obras Contra as Secas (DNOCS) and inaugurated on January 11 of that year. With a storage capacity of approximately 2.1 billion cubic meters, it stands as the second largest reservoir in Ceará — a title it held as the largest until the construction of Açude Castanhão in 2003. The reservoir sits at coordinates 6°14'19.68"S, 38°55'30"W and plays a critical role in water resource management for the semi-arid sertão region of northeastern Brazil. Its sheer scale, combined with its location in the Rio Jaguaribe basin, makes it a notable destination for anglers exploring the interior of Ceará.
