Aguieira Dam (Portuguese: Barragem da Aguieira) is a multiple-arch dam on the Mondego River, located on border line between the municipalities of Mortágua and Penacova, in Central Portugal.
Construction of the dam began in 1972 and was completed in 1981. It is owned by Companhia Portuguesa de Produção de Electricidade (CPPE). Besides power production the dam is also used for flood control, water supply and irrigation.[1]
Reservoir
At full reservoir level of 117 m (maximum flood level of 126 m) the reservoir of the dam has a surface area of 20 km² and its total capacity is 423 mio. m³. Its active capacity is 304 (216[2] or 253[3]) mio. m³. Minimum operating level is 100 m.[1] With the 216 mio. m³ water 39.2 GWh can be produced.[2] The reservoir submerged the villages of Breda (in the municipality of Mortágua) and Foz do Dão (in the municipality of Santa Comba Dão).
