Açude Cachoeira dos Cegos, also commonly known as Açude do Cego, is a reservoir located in the municipality of Catingueira, within the Região Metropolitana de Patos in the state of Paraíba, Brazil. Its coordinates place it at approximately 7°5'18"S, 37°39'15"W. The reservoir was constructed between 1992 and 1995 in the community of Várzea do Ovo, and its informal name derives from a local resident who had a visual impairment.

The reservoir has a total storage capacity of approximately 71,887,047 cubic meters and extends roughly 13 kilometers through the northern portion of the municipality of Catingueira. Water released from the dam supplies part of Catingueira as well as the entire neighboring municipality of Emas. The upstream area directly supports around 150 families and is noted for fish production.

Water levels in this reservoir can vary considerably from year to year, which is a relevant planning consideration for paddlers. Recorded levels have ranged from around 45.94% of capacity to as low as 26.75% within a span of a few years, reflecting the variable rainfall patterns typical of the semi-arid interior of Paraíba. Paddlers should verify current water levels before planning a visit, as low levels may significantly affect navigable area and access.

The reservoir sits within a rural, agricultural landscape with potential for agrotourism. No specific paddling infrastructure, designated access points, or formal facilities for paddlers are currently available at this location.
