Arachthos River: A Vital Waterway of Epirus, Greece
The Arachthos is a significant river flowing through the eastern Epirus region of Greece. Serving as both a geographical landmark and a critical resource for the local population, the river winds through diverse landscapes, from the rugged peaks of the Pindus mountains to the coastal lowlands of the Ionian Sea.

Course and Geography
The river begins its journey in the Pindus mountains, specifically near the town of Metsovo within the Ioannina regional unit. In its initial stages, the upper course of the river is known as the Metsovitikos. It only takes the name Arachthos after its confluence—the point where two or more flowing bodies of water join—with the Dipotamos river near the village of Batza.
As it flows southward, the river carves a path between the Athamanika and Xerovouni mountains. This stretch of the river is home to the Plaka Bridge, which holds the distinction of being the largest one-arch stone bridge in Greece.

Water Management and the Pournari Reservoir
Upon entering the Arta regional unit, the river is managed by the Pournari Reservoir. This massive reservoir, spanning approximately 18 km, serves two primary purposes: it prevents the city of Arta from flooding and provides a steady water supply to the majority of the Epirus region. The town of Peta is located in close proximity to this dam.
The City of Arta and the River Mouth
Approximately 8 km downstream from the dam lies Arta, the largest town situated along the river's course. Arta is famous for its own historic landmark, the stone Bridge of Arta, which crosses the Arachthos.

After leaving Arta, the river traverses the southern lowlands before finally emptying into the Ambracian Gulf near Kommeno, located 16 km southeast of the city.
