The Tâmega is more important historically than economically. It has always served as an invasion route for foreign armies intent on reaching the richer southern lands of Portugal. The valley around Chaves has especially seen its share of battles and invading armies.
Like many rivers, the Tâmega suffers from pollution and the ravages of sand and gravel extraction companies. The quality of the water has deteriorated greatly. Another problem is the periodic occurrence of flooding.
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.
A new dam is planned between the city of Amarante and the town of Mondim de Basto. Besides producing electricity, the project will feature a flood control system that will divert the waterflow towards the smaller Olo River. A 220 MW pumped-storage hydroelectricity facility started operating in 2022, storing 40 GWh of electricity. It cost €1.5 billion. Three more turbines are scheduled for the site, bringing the storage power to 880 MW. The project also includes two run-of-the-river hydroelectricity facilities.[1][2]
