The
Evinos is a 92 km long river in western
Greece, flowing into the
Gulf of Patras. Its source is in the northern
Vardousia mountains, near the village
Artotina,
Phocis. The river flows in a generally southwestern direction, for most of its length in
Aetolia-Acarnania. It feeds the reservoir of Lake Evinos, that is about 10 km². The river flows through a deep forested valley with few small villages. In its lower course it flows through lowlands, and it empties into the
Gulf of Patras 10 km southeast of
Missolonghi. The village
Evinochori near its mouth owes its name to this river.
