Barragem Corredores is a water storage dam located near Campo Maior in the state of Piauí, Brazil. The reservoir covers approximately 5 square miles, making it one of the larger water bodies in the region. Campo Maior is also home to at least one other major dam, Emparedado, in the same municipality.

Paddlers considering this reservoir should be aware of a significant safety concern: in early 2025, residents and advocacy groups reported the appearance of cracks and water seepage below the dam wall, raising concerns about structural integrity. The Movimento dos Atingidos por Barragens (MAB) called for urgent monitoring by civil defense and oversight agencies. Anyone planning to paddle here should verify the current structural status of the dam with local authorities before launching, as conditions near a dam under scrutiny present serious risks.

The reservoir is known to reach full capacity and overflow during periods of high rainfall, which can isolate nearby communities and affect access routes. No formal boat ramps or designated water access points exist at this location. Paddling regulations, wildlife, and water quality characteristics are not well documented.

Given the semi-arid climate of the Piauí interior, water levels can vary considerably between the rainy season and the dry season, which directly affects the usable surface area and access to the water's edge. Prospective visitors should consult local sources and the Secretaria do Meio Ambiente e Recursos Hídricos (SEMARH) of Piauí for current water levels and any safety advisories before planning a trip.
