Main image

Lake Polyfyto is an artificial reservoir in Western Macedonia in northern Greece, formed by the construction of a dam on the Aliakmon River. It functions primarily for hydroelectric generation and river flow regulation and created extensive shoreline where the flooded valley now lies.

The reservoir is visited mainly by local communities for fishing and limited recreational use; roads and small settlements lie along parts of the flooded valley. The dam and reservoir altered riverine landscapes and local land use when the impoundment was created.

Located in the regional unit of Western Macedonia, the reservoir lies inland in a broadly mountainous, river-valley landscape and serves as an infrastructural feature of northern Greece’s energy and water management.

  • Uses and access: The reservoir is an important local hydroelectric basin and also supports limited fisheries and shoreline roads used by local communities.

What to See #

  • Polyfyto Dam: The dam on the Aliakmon River that created the reservoir is the main structural feature and supports hydroelectric generation and water regulation for the region.

How to Get to Lake Polyfyto #

From Kozani, follow the Egnatia Odos westbound and take the exit toward Siatista/Grevena; local roads lead south to the Polyfyto dam area-expect a 40-60 minute drive. There is roadside parking near the dam and small access points along the reservoir for launching small boats.

Tips for Visiting Lake Polyfyto #

  • The road to the reservoir includes narrow stretches; drive cautiously on the local D-route access roads.
  • Take binoculars for raptor and kingfisher sightings along the shoreline.
  • Visit in late spring when the water level is moderate-extreme drought years reveal muddy embankments and affect boat access.
