The Sykia Dam is a mostly constructed but unused earth-filled embankment dam on the Acheloos River along the border of Karditsa and Arta, Greece. The 170 m (560 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 Sykia, Messochora, Mouzaki and Pyli Dams along with a 17.4 km (10.8 mi) long channel.
The idea for the Sykia Dam and overall diversion project was first envisioned in the 1930s but a lack of funding precluded construction. Interest in the project was revived in 1984 and construction on the dam began in 1996. Over the next several years there was a series of legal battles that led to final 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 Acheloss. Supporters call on the benefit to the lucrative cotton crops it will help irrigate and the dam's planned 120 MW hydroelectric power plant.[3]
