The Megdovas, also known as Tavropos, is a river that flows through the Karditsa and Evrytania regional units, Greece. It is 78 km (48 mi) long.
The river begins in the Agrafa mountains in the western part of Karditsa regional unit.
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.
