Açude Caxitoré is a large reservoir located in the municipalities of Umirim and Pentecoste in Ceará, Brazil. Built by the Departamento Nacional de Obras Contra as Secas (DNOCS) between 1958 and 1962, it sits on the bed of the rio Caxitoré, a tributary of the rio Curu. The reservoir has a total storage capacity of 202 million cubic meters, making it one of the more significant water bodies in the region. Its coordinates place it at approximately 3°46'S, 39°22'W.

The reservoir occupies a semiárido landscape characterized by irregular rainfall and high evapotranspiration rates. Water levels can vary considerably depending on rainfall patterns. After a prolonged period of low levels, the reservoir reached full capacity and overflowed in April 2024 — the first such event in 15 years — and again in 2025, the first time it had overflowed in two consecutive years. Paddlers should be aware that water levels may fluctuate significantly between wet and dry seasons, which could affect access and navigable area.

The surrounding area includes approximately 125 families settled on lands adjacent to the reservoir, with rural properties engaged in agricultural and livestock activities. The reservoir supports multiple uses, including water supply for the town of Umirim, fishing, bathing, and weekend leisure activities. The presence of livestock watering and clothes washing at the water's edge is worth noting for paddlers considering water contact.

Fishing is a recognized activity on the reservoir, and it is listed as a fishing destination, though access is noted as private. Paddlers should verify access permissions before launching. The broader area around Umirim has been included in Brazil's official tourism map, suggesting some level of visitor infrastructure in the municipality, though specific paddling facilities at the reservoir are not currently established.
