The Mesochora Dam is concrete-face rock-fill dam on the Acheloos River near Mesochora in Trikala, Greece. The 150 m (490 ft) tall dam is part of the Acheloos River Diversion which is intended to divert a portion of the Acheloos west to irrigate 240,000–380,000 ha in the Thessaly plains. The project includes the Mesochora, Sykia, Mouzaki and Pyli Dams along with a 17.4 km (10.8 mi) long channel.
