Reservoir of Trasona Nature · Corvera de Asturias, Avilés, Asturias The Trasona reservoir, in the concejo of Corvera de Asturias, is owned by ArcelorMittal Asturias and was brought into service in 1957 to supply water to the steelworks of the Avilés comarca and to the population then arriving in the area from various parts of Spain; it is fed by the Alvares and Narcea rivers, the latter through a 27-kilometre canal. Beside the reservoir stands the Trasona Sports Technification Centre, devoted to canoeing, which was refurbished in 2010 for the European Canoeing Championships, with a new control tower, a fixed stand for 300 people and a floating platform for medal ceremonies. The centre also has a residence for the Spanish federation's youth team and the offices of the Asturian federation. Photo: Mikel González (CC BY-SA 2.5 es) What to see and do in Corvera de Asturias
