The dam was completed in 1964. It is owned by the Companhia Portuguesa de Produção de Electricidade (CPPE).
Barrier structure
The barrier structure is a gravity dam with a height of 29 m above the foundation level (26 m above the river bed). The top of the wall is at a height of 906.5 m above sea level . The length of the top of the wall is 220 m and its width 4.74 m. The volume of the structure is 29,000 m³.
The dam wall has both a bottom outlet and a flood relief . A maximum of 27 m³ / s can be discharged via the bottom outlet, and a maximum of 410 m³ / s via the flood discharge.
Reservoir
With a normal storage target of 901.5 m (maximum 905 m at high water), the reservoir extends over an area of around 0.5 km² and holds 3.3 million m³ of water - of which 2 million m³ can be used.
