Mesochora Dam

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 (590,000–940,000 acres) 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.

The idea for an Acheloos to Thessaly diversion project was first envisioned in the 1930s but a lack of funding precluded construction. Interest in the project was revived in 1984 and what was supposed to be a small dam at Mesochora apart from the diversion project was increased in size to support to river diversion. Over the next several years there was a series of legal battles that led to construction stalling, most recently in 2005.[2] Opponents of the scheme cite significant changes to the environment, flooding of villages and that the scheme will divert 600,000,000 m3 (490,000 acre⋅ft) of water annually from the Acheloos. Supporters call on the benefit to the lucrative cotton crops it will help irrigate and the dam's planned 162 MW hydroelectric power plant.[3] The Mesochora Dam was completed in January 2001 but the reservoir has yet to be filled and the power plant has subsequently not been commissioned due to legal battles.[4]
