Alto Lindoso Dam (Portuguese: Barragem do Alto Lindoso) is a

Lima River. It is located in the municipality Ponte da Barca, in Viana do Castelo District, Portugal. The dam lies in Peneda-Gerês National Park close to the border with Spain
. The reservoir created by the dam is known as Alto Lindoso reservoir or Lindoso reservoir.

History

Construction of the dam began in 1983.

Aceredo, Buscalque, O Bao, A Reloeira and Lantemil, supported by left-leaning political parties, immediately began protests against the building of the dam,[2] including a ten-day hunger strike. In the end, with no option but to move, the residents of Aceredo (a town with 70 houses and 120 citizens) relocated bodies from their cemetery, and a historic church was moved to a different town. Some moved to nearby villages, others far away.[3]

The dam was completed in 1992 and drowned the five villages.[2] It is owned by Companhia Portuguesa de Produção de Electricidade (CPPE). The dam is used for power production.[1]

Dam

Alto Lindoso Dam is 110 m (360 ft) tall (height above foundation) and 297 m (974 ft) long double curvature arch dam with a crest altitude of 339 m (1,112 ft).[1] The width at the base is 21 m (69 ft) (crest 4 m (13 ft)).[4] The volume of the dam is 308,500 m3 (10,890,000 cu ft). The dam contains two shaft spillways with three gates each (combined maximum discharge 2,760 m3 (97,000 cu ft)/s) and two bottom outlets (combined maximum discharge 400 m3 (14,000 cu ft)/s).[1]

At full reservoir level of 338 m (maximum flood level of 339 m) the reservoir of the dam has a surface area of 10.72 km²

GWh of electricity can be produced.[7]

The formerly drowned village of

Aceredo in 2022 emerged again after prolonged drought.[8][9]

GWh.[7][10][6][1][5]

The power station contains 2 Francis turbine-generators of 317 MW (350 MVA) each in an underground powerhouse 340 m below the surface.[4] The turbine rotates at 214.3 rpm. The minimum hydraulic head is 227 m, the maximum 288 m. Maximum flow per turbine is 125 m³/s.[7]

As lower reservoir for Alto Lindoso the reservoir of Touvedo dam is used,[5] which is connected via a tailrace tunnel with a length of 4,883 m.[4][10]
