Açude Lima Campos, also known as Estreito I, is a reservoir situated in the Distrito Lima Campos within the municipality of Icó, in the centro-sul region of Ceará. It was constructed between April and December of 1932 on the Riacho São João, a watercourse belonging to the Bacia do rio Salgado. The dam is of earth-fill (terra zoneada) construction and holds a total capacity of approximately 66.38 million cubic meters, making it a substantial body of water for the region.

The reservoir is managed by the Departamento Nacional de Obras Contra as Secas (DNOCS) and serves primarily for water resource management, including irrigation and animal watering. The area has a local reputation for fish, and fishing activity is part of the cultural character of the surrounding community. Paddlers should be aware that piranhas have been reported in the water, which is a relevant safety consideration for anyone planning to enter the water or paddle close to the surface.

Tourism infrastructure at the reservoir is limited. The absence of dedicated bathing or recreational platforms is notable when compared to larger regional reservoirs such as Orós, indicating that formal amenities for water-based recreation are minimal. Paddlers should plan accordingly and not expect established launch facilities or on-site support services.
