Route of the Reservoirs on Catamaran
The narrow rugged passages that are typical of the Miño and Sil Rivers throughout the Ribeira Sacra favoured the building of reservoirs and hydroelectricity stations along many of the sections of those rivers. During the nineteen fifties and sixties the four great reservoirs of the area were built: Belesar and Os Peares in the River Miño, and San Pedro and Santo Estevo in the Sil.
