The Tabueira dam ( Portuguese Barragem de Tabueira ) is located in the Alentejo region of Portugal in the Évora district . It dams the Ribeira dos Pombos to a reservoir. The municipality of Ciborro is about a kilometer west of the dam.
The dam was completed in 1976. In addition to irrigation, it also provides drinking water. The dam is owned by the Cooperativa Agropecuária do Ciborro .
The barrier structure is a dam with a height of 23 m above the foundation level (22 m above the river bed). The top of the dam is at a height of 155 m above sea level . The length of the dam crest is 260 m and its width 6 m. The volume of the dam is 169,000 m³.
The dam has both a bottom outlet and a flood relief . A maximum of 17.86 m³ / s can be discharged via the flood relief. The design flood is 101.2 m³ / s; the probability of this event occurring has been determined to be once in 250 years.
With a normal storage target of 152.5 m (maximum 153.5 m at high water), the reservoir extends over an area of around 0.46 km² and holds 3.5 million m³.
