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 km, while the lake itself has an area of 7.5 km.
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. The critically stressed Monti della Maddalena faults become triggered by small-to-moderate magnitude reservoir-induced seismicity.
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 Puglia. It is one of the starting points of the Apulian aqueduct.
