Kremasta lake, Artificial reservoir in Central Greece

Kremasta lake is an artificial reservoir in Central Greece that covers a large water surface and forms several bays and small islands. Four rivers meet at this location, while two bridges cross the waters and connect different municipalities.

The Kremasta Dam was completed in 1965 and created Greece's largest artificial lake. The structure was built by concentrating waters from four rivers in a region that held economic and energy importance.

The lake's name comes from the village of Kremasta, submerged when the dam was built. Since 2022, daily guided boat tours run under the Greek Fjords programme, run by the regions of Western and Central Greece with the municipalities of Agrinio, Agrafa, Amfilochia and Karpenisi. Divers reached the sunken Episkopi monastery in September 2025 and found it well preserved.

The lake offers fishing and water sports opportunities that are accessible from several access points along the shore. The two bridges allow easy crossings and let visitors explore different areas of the lake from the land.

Beneath the water lie the villages of Episkopi, Agios Vasileios and Sidera, the 400-year-old Manolis bridge over the Agrafiotis, and the single-arch Tatarna bridge. In September 2025 a dive team led by Evangelos Papatzitzes descended to the flooded Byzantine monastery of Episkopi and found its church still in very good condition 60 years after submergence.
