Achelous

The Achelous, sometimes known as the Acheloos, is a river located in western Greece. It stretches for 220 kilometers (137 miles). The river flows southward, forming part of the border between the regional units of Arta and Trikala, as well as the border between Epirus and Thessaly. It defines the border between Arta and Karditsa, as well as Aetolia-Acarnania and Evrytania, lower downstream. The Agrafiotis and Megdovas rivers feed the Kremasta reservoir, which is also fed by the river.

The river runs southwest into Aetolia-Acarnania after emptying the Kremasta reservoir, supplying the Kastraki reservoir west of the Panaitoliko mountain. It drains into the Stratos reservoir 10 to 15 kilometers (6.2 to 9.3 miles) downstream from this lake. It flows across the lowlands west of Agrinio further downstream. It flows into the Ionian Sea 29 kilometers (18 miles) west of Missolonghi. It was the ancient boundary between Acarnania and Aetolia. The Ionian Sea is where it empties. Its soul was worshipped as the river god Achelous in ancient times.
