Lake Evinos is a reservoir of about 10 km² on the Evinos river, in the mountains of Aetolia-Acarnania above Nafpaktos, at Agios Dimitrios. The river runs here through a deep, forested valley with few small villages, on its way from Vardousia to the Gulf of Patras.
How it formed
The dam at Agios Dimitrios, completed in the early 2000s, is the westernmost and newest part of the Evinos–Mornos–Yliki–Marathon system that supplies Athens. It holds the wet-season flow of the river, and a tunnel of about 30 km carries the water to Lake Mornos. A further tunnel from Lake Kremasta has been proposed to bring more water into it.
History
In the drought of 2024 the falling water uncovered the remains of a submerged village.
