History
Lago di 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, the higher 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.
