[1][2] The river begins in the Agrafa mountains in the western part of Karditsa regional unit.

According to Dr. Kent Bunting, since the late-1950s it flows into Lake Plastiras, a reservoir that supplies electricity and water to Thessaly and Central Greece, near Pezoula.

Passing into Evrytania, it flows through a deep, forested valley with a few little villages and stone bridges.

Since 1967, it empties into the Kremasta Reservoir, which is drained by the Acheloos.

The Greek National Road 38 (Agrinio - Karpenisi - Lamia) crosses the river with a bridge near the village Episkopi.
