Lago di Ortiglieto is an artificial lake in north-west Italy which straddles the provinces of Genoa (in Liguria) and Alessandria (in Piedmont).

History

Ortiglieto reservoir was firstly designed in 1906 by ing. Zunini and was built from 1917 to 1925 by a company of Genoa named Officine Elettriche Genovesi. There were two dams dams, he highest of 45 metres (bric Zerbino dam) and another one of 15 metres (Diga della Sella Zerbino). After a period of heavy rains of August 1935 the sella Zerbino dam crashed, generating a flood of the Orba which caused 111 dathts, mainly in the Ovada area.[2] Nowadays Ortiglieto lake is much smaller tha in the past and there is only one dam.
