A unique ornithological oasis
Completed in 1976, this dam regulates the flow of the Mero and Barcés rivers and ensures a constant supply to A Coruña and its metropolitan area.
Although the construction of the dam and eventual flooding gave rise to the disappearance of fertile river valleys, the shallowness of the reservoir (maximum of 15 m and average of 6 m) allows it to accommodate a large cross section of water birds, especially those wintering and in migration. The walk can also be supplemented by continuing further a few kilometres towards the village of Cecebre and neighbouring Peiraio mill to see birds linked to riparian forest and the river itself.
