The Kastraki Dam 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. [2] [3] 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).

Embankment dam large artificial dam

An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil, sand, clay, or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core. This makes such a dam impervious to surface or seepage erosion. Such a dam is composed of fragmented independent material particles. The friction and interaction of particles binds the particles together into a stable mass rather than by the use of a cementing substance.

Achelous River River in western Greece

The Achelous, also Acheloos, is a river in western Greece. It is 220 km (137 mi) long. It formed the boundary between Acarnania and Aetolia of antiquity. It empties into the Ionian Sea. In ancient times its spirit was venerated as the river god Achelous.
