Is an earth-fill embankment dam on the Achelous River near the village of Kastraki in Aitoloakarnania, Greece. It was completed in 1969 for the purposes of hydroelectric power generator, flood control and irrigation. The dam's power station houses four 80 MW Francis turbine-generators for an installed capacity of 320 MW. In 2010 the dam's overflow chute spillway was upgraded with 20 fuse plugs which increased the maximum height of the reservoir by 1.93 m (6.3 ft) and its storage capacity by 44,000,000 m3 (36,000 acre·ft).
