Kremasta (lake) Reservoir

Address: Lake Kremasta (Kremasta), Western Greece

Hours: Open 24 hours

Kremasta is a large artificial reservoir in western Greece formed by damming the Acheloos River. It is the largest man-made lake in the country and plays a major role in regional water management.

The reservoir offers wide open water and wooded shorelines used for recreational boating, fishing and roadside viewpoints. The dam and associated infrastructure are visible features and are often the focus of short visits and photo stops.

The lake was created in the 20th century when the Acheloos was impounded to produce hydroelectric power and regulate river flows; the resulting reservoir inundated valleys and altered local settlement patterns.

Set within a mountainous valley in Western Greece, the reservoir lies across regional boundaries and is surrounded by steep forested slopes and small villages.

• Largest artificial lake: Formed by damming the Acheloos River, it is the largest artificial lake in Greece and serves hydroelectric, irrigation and flood-control functions.

What to See#

• Kremasta Dam: The concrete dam that created the reservoir and controls water levels for downstream hydroelectric and irrigation use.
• Reservoir shores: Open water and shoreline used for boating and angling; access points and small harbours are scattered along the reservoir.

• See the dam viewpoints-Kremasta has broad vistas best enjoyed in late spring and early autumn when surrounding hills are green and reservoir levels are moderate.
• Allow time to drive along the lake's scenic roads; viewpoints and small lay-bys adjacent to the main road provide far better perspectives than trying to view the lake from a single spot.
• If you're interested in photography or birdlife, visit in the early morning when light is best and wildlife along the shoreline is most active.
