Açude Poço Verde is a reservoir in the municipality of Itapipoca, Ceará, impounding the Riacho Sororó. Completed in 1955 by the DNOCS (Departamento Nacional de Obras Contra as Secas), it has a total storage capacity of approximately 13,650,000 m³ and a drainage basin of 63.4 km². It serves as one of the primary water supply sources for Itapipoca and supports an active artisanal fishing community.

The reservoir has an established paddling tradition. The Colônia de Pescadores Z3, with support from the Prefeitura de Itapipoca through the Secretaria de Desenvolvimento Agrário, Pesca e Recursos Hídricos, organizes canoe regattas on the water, including a dedicated women's division. These events draw both competitors and the broader community, reflecting the reservoir's role as a local gathering point.

Fishing is a central activity on the water. The Ceará state government has supported tilapia stocking programs here in recent years, and the reservoir sustains families engaged in subsistence and artisanal fishing. When the reservoir reaches capacity and spills over the sangradouro (spillway), traditional communal fishing at the overflow point is a culturally significant local event.

Water levels at Açude Poço Verde are subject to the rainfall patterns typical of the semi-arid Ceará interior, meaning the reservoir can fluctuate considerably between wet and dry seasons. Paddlers should be aware that access and navigable area will vary depending on the current fill level. The reservoir is monitored by COGERH (Companhia de Gestão dos Recursos Hídricos do Ceará).
