Reservoir of Mediano Nature · La Fueva, Sobrarbe, Huesca The Mediano reservoir lies within the municipal district of La Fueva, to which the village of Mediano was incorporated in 1974, its centre having been flooded by its waters. It is one of the largest reservoirs in Aragon, with a surface area of 1,714 hectares and a total capacity of 436.35 cubic hectometres. Its dam rests on the limestone rock of the El Entremón gorge, on the river Cinca, a few kilometres from the tail of the El Grado reservoir, which it regulates; its release allows electricity to be generated at an underground power station, operated first by ENHER and today by Acciona. It is managed by the Confederación Hidrográfica del Ebro. Photo: Jesus Abizanda (CC BY 2.0) What to see and do in La Fueva
