Lake Kremasta (Greek: Λίμνη Κρεμαστών) is the largest artificial lake in Greece. The construction of Kremasta Dam was completed in 1965 concentrating waters from four rivers: Acheloos, Agrafiotis, Tavropos and Trikeriotis. The water that is accumulated in the artificial lake is about 3.8 cubic kilometres (3,100,000 acre⋅ft).^[2] In addition to supplying energy to the national grid during times of high demand, it avoids flooding of the Acheloos. The power station at the dam is the biggest hydroelectric plant in Greece (rated power: 437.2 MW). It was constructed in 1966 and is owned by the Public Power Corporation of Greece (DEH A.E.). At the time of its construction, it was the largest earth-filled hydroelectric project in Europe.^[3]
