Kastraki lake, reservoir in Greece

Kastraki lake is a reservoir on the Acheloos in Aetolia-Acarnania, formed where the river meets its tributary the Inachos. Its surface covers about 28 km². The Kastraki Dam holding it back is 95 m high, 530 m long and 380 m thick at its base.

The lake was created in the late 1960s with the completion of the Kastraki dam in 1969. The dam transformed the Acheloos river valley, flooding former farmland and small settlements that once stood in the area.

The lake's name comes from the nearby village of Kastraki, and the shore is also shared with Babalió. When the reservoir filled, the waters covered almost all the land of Malateika and Babalió, and most residents were forced to emigrate; a small part of them rebuilt settlements beside the lake.

The lake lies near the villages of Kastraki and Babalio in Aetolia-Acarnania, where the Acheloos meets the Inachos. The dam stands 95 m high and 530 m long, with a 380 m thick base. Approach by road from these villages; the shoreline is steep in places, so plan walks accordingly.

The Kastraki Dam is 95 metres high, 530 metres long and 380 metres thick at its base; the DEI hydroelectric station at its foot saves substantial quantities of oil and the pollution it would cause. The lake's water covered almost all the land of the villages Malateika and Babalio, and most residents were forced to emigrate.
