The Volturno River is the main water watercourse of southern Italy both for length and surface of the supply basin. Spring waters flow at the foot of Monte della Rocchetta; they are outcrops of groundwater bodies relating to the carbonate massifs typically found in the area between Abruzzo and Molise. From 1948 to 1958, the Ente Autonomo Volturno (E.A.V.), under the guidance of Eng. Luigi D’Amelio and Eng. Giuseppe Archivolti – and the technical management of Eng. Guido Bourelly – elaborates an ambitious strategic plan to use the water source from the highest part of the Alto Volturno basin. The new plan included the construction of a hydraulic work of regulation of outflows coming from the Meta mountains, by using three different dams able to contain an artificial basin of 9 Mm 3 .
