Tâmega (river)

The Tâmega (European Portuguese: [ˈtɐmɨɣɐ]) or Támega (Galician: [ˈtamɪɣɐ]; Proto-Celtic: *Tamaca) is a river in Galicia, Spain and Portugal.

It has always served as an invasion route for foreign armies intent on reaching the richer southern lands of Portugal.

Since the completion of the Torrão dam in 1988 less than 1 kilometre above the Douro river and the town of Entre-os-Rios in the municipality of Marco de Canaveses, the Tâmega has been recovering slowly from the effects of pollution.

Sand extraction activities have been prohibited and many upstream cities installed modern sewage treatment plants.

Besides producing electricity, the project will feature a flood control system that will divert the waterflow towards the smaller Olo River.
