The Vale do Rossim dam ( Portuguese Barragem de Vale do Rossim ) is located in the Central Portugal region in the Guarda district . It dams the Ribeira da Fervença to a reservoir. The dam is located in the Parque Natural da Serra da Estrela nature reserve . The small town of Seia is about ten kilometers to the northwest.

Barrier structure

The barrier structure is a gravity dam made of masonry and concrete with a height of 27 m above the foundation level (17.46 m above the river bed). The top of the wall is at a height of 1,437.5 m above sea level . The length of the wall crown is 375 m and its width 1.5 m. The volume of the structure is 25,000 m³.

The dam wall has both a bottom outlet and a flood relief . A maximum of 10 m³ / s can be discharged via the bottom outlet, and a maximum of 66 m³ / s via the flood discharge.

Reservoir

With the normal storage target of 1,436 m (maximum 1,436.75 m at high water), the reservoir extends over an area of ​​around 0.37 km² and holds 3.5 million m³ of water - 3.4 million m³ of this can be used.

The reservoir is connected to the reservoir of the Lagoacho dam via a tunnel with a length of 3,270 m . From there a 2,330 m long canal runs to a storage basin. A 2,120 m long penstock then leads from this reservoir to the Sabugueiro II power plant.
