Kremasta Dam

The Kremasta Dam is an earth-fill embankment dam on the Achelous River in Aetolia-Acarnania, Greece. It is located just downstream of where the Agrafiotis, Tavropos and Trikeriotis rivers meet to form the Achelous. The dam was constructed between 1961 and 1965 and its four 109.3 MW Francis turbine-generators were commissioned between 1966 and 1967. Shortly after the dam's reservoir, Lake Kremasta, was filled a 6.3-Mw earthquake occurred. This has been attributed to reservoir-induced seismicity. Lake Kremasta is the largest artificial lake in Greece.[4][5]
