History

In the 1960s, the government began building an earth-shaped dam named the ''Peneus Dam'' (Φράγμα Πηνειού ''Fragma Pineiou'') to supply water for the north and much of Elis. The dam is considered the highest dam in Elis. In Greek mythology, the Peneus and Alpheus were two rivers re-routed by Heracles in his fifth labour in order to clean the filth from the Augean Stables in a single day, a task which had been presumed to be impossible.
