Lago di Pietra del Pertusillo is an artificial lake in the Province of Potenza, Basilicata, Italy. At an elevation of 532 m, its catchment basin area is 630 km2, while the lake itself has an area of 7.5 km2.
Geography Because of water table oscillations in the region and other local effects, it has been documented that the artificial lake has affected regional tectonics and has increased the magnitude of microearthquakes.Spatio-temporal evolution of ground motion intensity caused by reservoir-induced seismicity at the Pertusillo artificial lake (southern Italy) The critically stressed Monti della Maddalena faults become triggered by small-to-moderate magnitude reservoir-induced seismicity.
The lake is part of the municipalities of Grumento Nova, Spinoso and Montemurlo. Other closest places are Viggiano and Villa d'Agri.
Dam The arch-gravity dam is 380 meters long and 95 meters high. Its construction has created a reservoir of 155 million cubic meters of water capable of supporting multiple uses of water resources, such as the exploitation of hydroelectric energy and the irrigation of over thirty-five thousand hectares of land between Basilicata and Apulia. It is one of the starting points of the Apulian aqueduct.
Type: masonry arch-gravity Actual start of construction: 1957 End of construction: 1962 Total height: 95.00 m Maximum reservoir level: 532.00 (m above sea level) Maximum flood level: 531.00 (m above sea level) Total reservoir capacity: 155 million m³
